TestChimp now supports native mobile testing

TL;DR: TestChimp now supports native mobile app testing on both iOS and Android. This brings the same seamless workflow we unlock for your web testing - just say "/testchimp test".

TestChimp native mobile testing support


What shipped

Mobile is not a separate product bolted on the side. It is the same plan → repo → agent → CI loop you use for web SmartTests, extended to native apps via Mobilewright—a Playwright-style API and toolchain for iOS and Android.

Create a TestChimp project with project type iOS or Android, connect Git for your plans and tests folders, install the TestChimp skill on Claude or Cursor, and after each PR say /testchimp test. The platform keeps doing what you expect: wiring RUM, reading scenarios, closing coverage gaps, and surfacing analytics—now on screens that live inside your app, not only in the browser.

For setup details and parity tables, see Mobile testing (iOS and Android).


Five value props for Claude-based test authoring—four are live on mobile

TestChimp’s agentic QA model rests on five pillars. On native mobile, four are fully supported today:

Value propWhat it gives youMobile status
Requirement traceabilityPlans ↔ tests feedback loop; scenarios stay linked to coverageSupported
TrueCoverageReal user behaviour ↔ tests feedback loop; production informs what to automateSupported
QA workflow executionSeed/probe endpoints, fixtures for reusable world-states, test authoring, scenario linkingSupported
ExploreChimpAnalytics on screenshots, logs, and network from exploratory runsSupported
Smart StepsIntent-based steps in test scripts (ai.act, ai.verify, …)Not yet

Smart Steps remain web-only for now. Native mobile tests use standard Mobilewright APIs for UI interaction—the same deterministic, async execution model you know from Playwright, without the intent-comment layer on top.

Everything else—the closed loops between requirements, production behaviour, fixtures, and tests—carries over.


The same seamless workflow as web

You do not need a new playbook. The habit stays the same:

  1. Install the TestChimp skill on Claude or Cursor.
  2. After each PR, run /testchimp test (or your team’s equivalent in the agent host).

TestChimp then orchestrates the work you would otherwise stitch together manually:

  • RUM libraries — Wire up testchimp-rum-ios and testchimp-rum-android so production and test runs speak the same event vocabulary.
  • Instrumentation — Understand real user behaviour: segments, interaction flows, and scenarios—not just “the app launched.”
  • Plans and stories — Read markdown scenarios, pull requirement traceability insights, and see what is still untested.
  • Test authoring — Author Mobilewright tests to cover gaps, with traceability annotations where your plan expects them.
  • Spot analytics — Run ExploreChimp-style analysis on new screens: visuals, logs, network.

You still get continuous transparency of QA posture in one platform—requirements, coverage, failures, and exploration—whether the surface is a browser tab or a native view controller.


Familiar tests, less flakiness

Mobile tests are authored in a Playwright-familiar style via Mobilewright: auto-waits, async execution, and fixtures that behave like the ecosystem you already trust on web. That consistency matters when agents (and humans) move between repos that ship both web and mobile.

Fair credit where it is due: the reliability characteristics of that execution model come from Mobilewright—and we are grateful they exist. Mobilewright moved our timeline for serious native support forward by at least a year. If you need cloud-hosted real devices in CI, Mobile Use integrates with the same stack.


What to do next

If you are already on TestChimp for web, create an iOS or Android project, point Git at your plans and tests folders, and run /testchimp test on your next mobile PR. Smart Steps will follow; the feedback loops you care about for shipping quality are already there.

SKILLs are becoming SaaS’s best distribution hack (here’s why)

For years, the hardest part of selling a complex technical product was not the demo—it was the learning curve. Buyers had to internalize workflows, edge cases, and “the right way” to use each feature before they could reliably get value.

That is changing fast. Agent Skills—portable folders of instructions, checklists, and resources that teach an AI agent how to work with your product—are starting to look like one of the most attractive distribution mechanisms for technical SaaS. Instead of hoping every customer reads the docs in the right order, you ship a repeatable operating procedure the agent can follow on demand.

A skill turns every “new user” into a “power user”

A well-designed Agent Skill effectively turns every user into a power user: one that knows which workflows to follow, how to use the product correctly, and how to extract maximum value from every feature.

That compresses time-to-value—the path to the “aha moment”—because the agent is not improvising from vague prompts; it is executing your intended playbook.

What we are seeing at TestChimp

We have been seeing this firsthand since launching the TestChimp Agent Skill.

For teams, the workflow is intentionally simple:

  1. Author a few user stories (or import from Jira).
  2. Install the TestChimp skill on your coding agent.
  3. After each PR, simply say /testchimp test.

The skill teaches Claude how to coordinate with TestChimp to:

  • instrument the app for TrueCoverage,
  • fetch and interpret coverage gaps,
  • write tests that addresses the gaps and link them to scenarios correctly,
  • run targeted exploratory testing to catch UX issues,
  • and use AI-native test steps in tests where they help.

The upgrade loop: your perfect user ships with your product

The best part is what happens when you ship new features.

With a properly designed, self-updating TestChimp Agent Skill, your "user" continuously learns your latest workflows, capabilities, and best practices—and applies them the way you intended. Your agent-side “instruction manual” can move as fast as your product, without requiring every human user to re-read release notes and learn every new capability you ship.

If you are building technical SaaS in the agent era, the product surface area is no longer only your UI and APIs. It is also the skill: the packaged expertise that turns your users in to power users.

TrueCoverage for agentic QA: learn how users really behave, then evolve tests on purpose

· 11 min read
Nuwan Samarasekera
Founder & CEO, TestChimp

If you are an autonomous QA agent, your hardest problem is not syntax. It is prioritization under uncertainty: which journeys matter, which world-states recur in the wild, and which gaps actually de-risk the product. If you are a human delegating QA to an agent, your hardest problem is trust: how do you know the agent is not optimizing for easy coverage while the business burns on paths real users depend on?

Production Feedback Loop enabled by TestChimp

TrueCoverage is a way to ground both sides in the same signal: what production traffic is trying to tell you, expressed in a form tests can participate in. This post is framed in two layers:

  1. Concept and utility — what TrueCoverage means independent of any vendor, why it fits the agentic era, and what becomes feasible once you have it.
  2. How TestChimp implements it — how @testchimp/rum-js, and @testchimp/playwright plugin, and summarized analytics APIs close the loop so agents (and humans supervising them) can learn, decide, and evolve QA continuously.

Part I — The idea: production as the curriculum for QA

What “TrueCoverage” means as a concept

Classical coverage answers: did my code execute? That is necessary and insufficient. It does not tell you whether the behaviors users rely on are the behaviors your suite exercises under conditions that resemble reality.

TrueCoverage, means:

  • You observe meaningful user-journey steps in production (not every click—semantic steps that map to product risk: checkout started, export completed, permission denied, and so on).
  • You observe the same vocabulary during automated test runs, with a way to know which tests produced which events.
  • You compare the two streams so you can see demand, sequencing, friction, and slices of the real world (roles, entitlements, cart shape) where real usage and automated coverage diverge.

The outcome is not a bigger dashboard. It is a closed feedback loop: production teaches you what “normal” and “important” mean for this product; tests and fixtures prove you still protect those paths after every change.

Why this approach matches how good agents already work

Agents that ship useful QA behave like scientists with a budget: they form hypotheses (“checkout without a saved payment method might be undertested”), gather evidence, run a targeted experiment (a test + fixture), and update the model. The weak link is almost always evidence. Product specs are incomplete. Ticket backlogs are biased. Code coverage is blind to which user stories matter.

Production behavior is imperfect—sampling, seasonality, and product experiments all apply—but it is ground truth for impact ordering. When an agent can query “how often does this situation occur?” and “what usually happens next?”, it stops guessing which regressions would hurt the most.

The elephant in the room: instrumentation used to be expensive

For years, the honest reason teams did not do this everywhere was operational cost:

  • Designing event names and metadata so they are stable, low-cardinality, and privacy-safe is skilled work.
  • Plumbing init, helpers, env-specific keys, and batching behavior across a large frontend is tedious.
  • Maintaining that layer across refactors—without breaking analytics or leaking identifiers—is ongoing tax.
  • Interpreting raw event lakes often required a data partner, not a QA engineer.

So the idea of aligning tests with real journeys was always sensible; the implementation and upkeep were the barrier. Teams defaulted to intuition, bug history, and line coverage because those scaled with human attention spans.

Why that burden collapses in the agentic era

Agentic coding changes the economics:

  • Boilerplate (init wrappers, typed emit helpers, progress trackers, event documentation) is exactly the sort of work models do quickly and consistently.
  • Refactor propagation—rename a flow, split a route, move state—becomes a task you can assign: “keep emitCheckoutProgress aligned with the new module boundaries.”
  • Governance at scale—dot-scoped metadata keys, cardinality rules, “no raw IDs in metadata”—can be enforced as repeatable policies in code review and in agent instructions, not as tribal memory.

What becomes feasible once agents can “see” real usage

Below are some capabilities that gets unlocked when an agent can pull summarized production-test deltas on demand.

1. Fixtures that mimic real-world situations—not demo data

Suppose checkout emits a semantic event checkout_attempted with bounded metadata such as user.has_fop (form of payment on file: true / false). Production aggregates might show that a large share of attempts happen with user.has_fop=false, while your automated runs almost always hit true because the seed user is “too perfect.”

An agent can:

  • Treat that skew as a coverage gap on a risk-bearing slice, not a vanity metric.
  • Author or extend a Playwright fixture (or API seed flow) that creates a user without FOP, then add a test that asserts the expected behavior (validation, alternate payment path, error copy, telemetry).
  • Document the event slice in repo-local knowledge (plans/events/*.event.md style) so the next agent does not reinvent the schema.

The point is not “more metadata.” The point is metadata that matches how the product branches in reality, so fixture work is evidence-backed.

2. Journey prioritization from sequences, not screenshots

Agents excel at graph-like reasoning when you give them a graph. TrueCoverage-style child event trees and transition summaries answer questions humans ask in war rooms—“after someone opens the importer, what do they actually do next?”—without watching session replays for hours.

Example: production might show that after import_started, the modal next step is usually mapping_confirmed, but a non-trivial fraction goes to import_cancelled within seconds. If tests always march the happy path to mapping_confirmed, you may be blind to early abandonment bugs (performance, confusing copy, default file type issues).

An agent can prioritize a short journey test for the high-drop branch, or an instrumentation pass if the “cancel” events are too coarse to explain why.

3. Using Demand, Duration, Drop-off, and Depth as a shared prioritization language

TrueCoverage analytics align well with a compact strategy: the 4Ds (how TrueCoverage metrics work)—Demand (how often something shows up), Duration (dwell and pacing), Drop-off (abandonment and terminal sessions), Depth (where a step sits in the funnel). Depth is especially important for prioritization because top-of-funnel steps guard everything downstream: if sign-up, workspace creation, or the first checkout screen is flaky, slow, or wrong, users and sessions never reach the deeper flows your suite might obsess over—so automation that skips straight to “step seven” can look green while production is bleeding at the door.

Together the 4Ds steer agents away from covering easy code and toward protecting painful journeys.

Concrete prioritization examples:

  • High demand + absent in test-tagged traffic → add or extend regression coverage soon.
  • Early funnel (shallow depth) + high demand or high drop-off → harden entry paths first: stronger tests, fixtures, and instrumentation for the gate events; defer deep-journey expansion until those steps are reliably exercised—otherwise you optimize coverage for journeys most real sessions never complete.
  • High drop-off + shallow tests → add negative paths, resilience, and performance-aware checks.
  • High duration → broaden scenarios (large payloads, slow networks) rather than a single happy-path click-through.

This is the difference between an agent that writes “a test” and an agent that writes the test the business would have asked for if it had perfect memory of last month’s traffic.

4. Continuous “evolve QA” instead of annual suite audits

When digestible analytics are API-accessible, QA improvement becomes a loop aligned with shipping:

Analyze aggregated production vs automated scopes → Plan instrumentation/tests/fixtures → Execute in the repo → Verify in CI → repeat on the next meaningful traffic shift.

Humans stay in control of goals and risk appetite; agents handle volume, consistency, and follow-through.


Part II — How TestChimp turns the concept into an agent-ready system

The conceptual loop needs three mechanical pieces: emit in the app, tag during automation, compare in a platform. TestChimp wires all three and exposes the result as summaries agents can consume without becoming data engineers.

TrueCoverage powered agentic QA loop in TestChimp

1. @testchimp/rum-js: production speaks the same language as tests

The application under test integrates @testchimp/rum-js (see the library README for init, emit, flush, configuration, and event constraints). Typical practice:

  • Call testchimp.init() once at bootstrap with projectId, apiKey, and an environment tag (for example production vs staging).
  • Prefer a single helper (for example emitProductEvent) wrapping testchimp.emit({ title, metadata }) so event names and metadata stay consistent.
  • Control volume through config (caps per session, repeats per title, batching intervals, kill switches)—agents can tune this deliberately instead of flooding pipelines.

Agent-relevant discipline: keep titles semantic (subscription_renewed) rather than noisy (blue_button_clicked). Keep metadata low-cardinality and non-identifying—think user.role, org.plan_tier, cart.is_empty—not raw IDs or free text. That is how the platform can return per-value coverage without privacy explosions. Dot-scoped keys like user.has_fop help agents map analytics slices directly to fixture dimensions.

Product overview: TrueCoverage intro.

2. Playwright reporter: the same events, tagged with test identity

Automated runs are only comparable to production if tests emit the same event titles (or a deliberate, documented mapping) and the platform can tell automation apart from anonymous traffic. TestChimp’s Playwright integration—@testchimp/playwright—tags RUM events with test identity during runs so coverage comparisons can answer: “Did this suite actually exercise checkout_attempted in the last seven days of CI?”

That is what makes “coverage” mean behavioral coverage of real journeys, not merely “we ran N tests.”

3. Execution scopes: compare apples to apples, on purpose

Agents should treat scopes as first-class inputs (see TrueCoverage workflow docs in your agent instructions). In practice:

  • A base scope anchored on the environment that best reflects real users (often production) drives funnel-relative metrics: frequency, transitions, terminal behavior, session counts.
  • A comparison scope (often QA or staging) answers what automation (or a specific branch/release) is doing in the same vocabulary.
  • automationEmitsOnly on comparison or child-tree scopes is how you ensure “covered” means test-tagged emits, not a manual tester clicking around on the same environment.

Getting this wrong is how teams accidentally overstate coverage. Getting it right is how agents earn trust from humans who offload QA.

4. Data APIs and MCP tools: digested signal for decisioning

TestChimp exposes TrueCoverage through APIs mirrored in MCP tools (for example list-rum-environments, get-truecoverage-events, get-truecoverage-event-details, get-truecoverage-child-event-tree, transition and time-series endpoints, metadata key discovery). The agent workflow is intentionally summary-first:

  1. List environments → pick stable tags for base vs comparison.
  2. Fetch event summaries → find high-impact titles with weak or absent coverage status vs the comparison scope.
  3. Drill into details → metadata distributions, example sessions, next-event trees.
  4. Translate gaps → SmartTests, fixtures, seed endpoints, or new emits if the product changed but telemetry did not.

Because payloads are aggregated—frequencies, histograms, coverage badges—agents can make informed plans without pulling raw session oceans into the context window.

5. Closing the loop: from insight to repo changes to measurable improvement

The full agentic story looks like this in practice:

  1. Instrument with rum-js using repo conventions (shared helper, env-based keys, documented events).
  2. Run Playwright suites with the reporter so emits carry test identity.
  3. Query TrueCoverage summaries after meaningful windows (release, marketing push, seasonal spike).
  4. Decide using 4Ds + transitions + metadata slices what to add or fix.
  5. Implement tests and fixtures; optionally evolve instrumentation when new risk-bearing branches appear in the UI.
  6. Re-query to confirm the comparison scope now hits the slices that production demanded.

That is autonomous QA with a compass: still bounded by human policy (privacy, release priorities, acceptable sampling), but no longer guessing whether the suite matches reality.


Who this is for

  • Agents: treat TrueCoverage as your grounding layer—the bridge from “what humans wrote in tickets” to “what the world actually does.” Use it to prioritize fixtures, journeys, and instrumentation before you spend budget on breadth nobody needs.
  • Humans offloading QA: ask for scopes, metadata discipline, and before/after dashboards—simple checks that the agent is optimizing production-aligned risk, not arbitrary line counts.

Accountable product and compliance choices still sit with people; TrueCoverage cheapens the cost of being well-informed—for agents reasoning over code and humans steering risk—which, in the agentic era, is the difference between automation that merely runs and automation that continuously earns the right to ship.

Prioritize Test Cases based on Real User Behaviour - TrueCoverage

· 3 min read
Nuwan Samarasekera
Founder & CEO, TestChimp

Most testing strategies are built in isolation from how users actually use a product.

Teams typically decide what to test based on:

  • feature specifications
  • developer intuition
  • past bugs

But production tells a different story.

Some features get heavy usage.
Some interactions are part of critical journeys.
Some screens are where users consistently drop off.

If your testing strategy doesn’t account for this, QA effort is being optimized in the dark.

This is the problem TrueCoverage solves.

TrueCoverage UI


Start With Real User Behaviour

TrueCoverage analyzes event data from production alongside events generated during test runs.

Instead of only measuring which tests executed, it looks at how users actually move through your product.

From this data, TestChimp derives four signals — what we call the 4Ds — to guide smarter QA planning.


The 4Ds of Product Behaviour

Event core stats

Demand

How frequently an event or interaction occurs.

High-demand interactions represent the most commonly used parts of your product.

Ensuring these features are covered in regression tests delivers the highest ROI by protecting the core capabilities of your application.


Depth

Where an interaction occurs in the user journey.

Depth distinguishes top-of-funnel interactions from deeper product workflows.

Early interactions often influence:

  • onboarding success
  • activation rates
  • user satisfaction

Testing depth helps ensure your QA strategy protects the critical entry points of your product.


Duration

How much time users spend interacting with a feature.

High duration often indicates either complex workflows or user friction.

Both require deeper testing. These areas benefit from:

  • scenario-based tests across different paths
  • validation of edge cases and error conditions
  • robustness testing for complex flows

Duration highlights where more thorough testing is needed beyond the happy path.


Drop-off

Where users exit a journey.

Drop-off points are some of the highest-value areas for testing.

If many users abandon the product at a particular step, that interaction deserves attention.

Testing around drop-off points helps uncover:

  • hidden bugs
  • validation issues
  • confusing UX
  • performance bottlenecks

Turning Behaviour Into QA Strategy

The 4Ds transform production behaviour into actionable testing insights.

For example:

  • High demand events → prioritize regression coverage
  • Top-of-funnel interactions → ensure reliability and stability
  • High drop-off points → investigate bugs or UX issues
  • Long duration flows → add scenario tests covering variations

Instead of guessing where to invest testing effort, teams can align QA with real product usage.


TrueCoverage

TrueCoverage compares:

  • event sequences from production
  • event sequences from test runs

This reveals the gap between:

  • what users actually do
  • what your tests actually cover

When that gap becomes visible, improving coverage becomes far more targeted.

Not more tests, but better tests aligned with real user behaviour.


Because ultimately, quality isn’t defined by how many tests you run.

It’s defined by how well your tests protect the journeys your users depend on.

In testing theory, this approach is referred to as "Signals Based Testing" - coined by Wayne Roseberry of Microsoft, and cited on leading books on Testing such as Taking Testing Seriously.

Your E2E tests are unreliable? Here's why

· 6 min read
Nuwan Samarasekera
Founder & CEO, TestChimp

End-to-end tests are a necessary evil: they are the last line of defense that something actually works in a real browser—but they break often enough that the suite becomes a burden instead of a trustworthy signal.

There are three main sources of variance that make E2E tests unreliable. Understanding them is the first step toward a suite you can actually rely on.

1. World-state variance

This is what happens when your tests run in a different world-state than the one they were written against. A common cause is a shared environment where manual testing and automated runs both happen. The world changes between runs; the next run fails for reasons that have nothing to do with the code under test.

This kind of variance does more than flake tests. It also slows feedback: if those environments only get updates after PRs merge to main, you get weaker root-cause isolation and more expensive triage when something breaks.

2. System variance

These are variances built into the stack itself: network latency, transient failures, UI paint timing, and so on. Mature frameworks like Playwright address a lot of this with built-in waiting, auto-waiting locators, and expect polling—so a big slice of “flakiness” is really tooling and patterns, not fate.

3. Product variance

Even in a steady state (with no product change) — modern web apps are not as simple as calculators. Behavior can be inherently non-deterministic, and that is only more true now that AI often sits in the user journey (for example, a splash or offer that appears only sometimes). Much of that variance may be irrelevant to what a given test is trying to prove.

When tests are authored with a fragile, UI-selector-heavy approach, those product-level variances show up as broken steps. The test is coupled to incidental UI, not to intent.


Solve for these three kinds of variance, and you get a suite that is finally trustworthy.

World-state variance → controlled environments

Use ephemeral environments loaded into known, predefined world-states, so each run matches the state the test was authored against as closely as possible.

System variance → solid automation primitives

This is largely where mature frameworks shine. With Playwright, you get strong primitives for timing and stability—so you are not reinventing waits on every test.

Product variance → intent where the UI is messy

This is where agentic steps in tests can help: natural-language instructions executed by an AI, instead of brittle coupling to selectors—only on the messy, flaky parts of the flow.

There is no free lunch: natural-language steps tend to be slower, costlier, and harder to debug than plain script. The goal is to use them surgically, not everywhere.

SmartTests: intent-based Playwright scripts

That tradeoff is what TestChimp SmartTests are designed around: intent-based Playwright scripts.

They are still scripts for the most part, with an extra capability when you need flexibility—the parts of the app that fight selector-based automation.

Instead of:

await page.locator('.anticon.anticon-plus-square.ant-tree-switcher-line-icon > svg').nth(1).click();

Now you can write:

await ai.act('Expand the tree displayed in the left pane');

Only where you need it—the brittle, shifting UI—not for every line of the test.

Because the tests remain Playwright-based, system variance is handled by the same patterns and tooling you already trust. Run them in ephemeral environments with controlled world-states, and you have a test suite with all 3 variances accounted for - a suite that you can trust.

And yes, we are cooking up something on the ephemeral-environment side too. Stay tuned...

Simplified View: No-Code Editor - Full Code Power

· 3 min read
Nuwan Samarasekera
Founder & CEO, TestChimp

TestChimp tests have always been plain Playwright under the hood — with extra capabilities like plain-English steps and lightweight scenario linking via code comments. That gives you fixtures, hooks, page objects, and the test organization you expect from a serious engineering setup.

Most QA teams are a mix of technical and non-technical teammates. Code-only authoring keeps contribution narrow. A separate no-code tool often means a second suite that drifts from the “real” tests and never gets the same CI treatment.

We added Simplified View in the web IDE so you do not have to choose.

SmartTests Simplified View in the web IDE

What Simplified View Is

Simplified View is a no-code surface for creating and editing SmartTests that still compiles to fully functional Playwright scripts. Everyone works on the same test; people just choose how they interact with the tests.

Your teammates can:

  • Add plain English steps - that are run agentically.
  • Use structured building blocks for common actions — less boilerplate and fewer syntax slips.
  • Drop in free-form code when you need it — custom waits, tricky selectors, helpers: full Playwright, no lock-in.

You pick the level of code per step and per person, not one rule for the whole team.

Why this matters

Non-technical members can contribute directly to test automation — not only by filing tickets for engineers to translate later. They build and edit steps in Simplified View; the result is still Playwright your automation folks can refine, reuse, and run in the same pipelines as everything else.

That lifts throughput for the whole team: more people can ship checks in parallel, fewer scenarios sit in a queue waiting for a coder, and engineers spend time on structure and hard cases instead of retyping flows from docs. Underneath, it stays real Playwright — deterministic runs, familiar debugging, ExploreChimp, CI, and Git workflows you already rely on.

Getting Started

Open a SmartTest in the web IDE and switch to Simplified View to author or edit steps. When you need the full script, switch to code view; both views stay aligned with the same underlying test.

Shift-Left with Git Branch-Aware Testing

· 4 min read
Nuwan Samarasekera
Founder & CEO, TestChimp

The traditional QA bottleneck is a well-known pain point for modern development teams. For years, the industry has pushed to "shift-left" – to move testing earlier in the development lifecycle. However, a major technical hurdle has always remained: the environment gap.

When QA happens on a global "staging" environment or only after code merges to the main branch, the feedback loop is too slow. Bugs found post-merge cause expensive context-switching for developers and delay releases.

Today, we’re bridging that gap. We’ve added full branch awareness to the TestChimp platform, enabling true shift-left testing at the PR level.

Shift-Left Git Testing

Why Branch-Aware Testing?

Branch-aware testing means your QA process mirrors your Git workflow. Instead of testing "the app," you test the "feature-in-progress."

1. Test Authoring at the Feature Level

You can now switch between repository feature branches directly within TestChimp. File versions are maintained per branch, allowing QAs to sync with branch-specific remote content.

Most importantly, QAs can author tests and raise Pull Requests from TestChimp that merge directly into the feature branch. This ensures that by the time a developer is ready to merge their code, the corresponding tests are already part of the PR.

[!TIP] Security & Outsourcing: Our new GitHub App-based approach means you don't need to give external QA resources full repository access. They can work exclusively on the tests and plans folders (with PRs raised via TestChimp platform), maintaining a tight security posture.

2. Branch-Specific Test Execution

Gone are the days of manually pointing tests at different URLs. In your project settings, you can now configure a template string for branch-specific deployment URLs (e.g., Vercel or Netlify preview URLs).

When you run tests on a branch, TestChimp resolves the correct URL and injects it as a BASE_URL environment variable. Your scripts simply consume process.env.BASE_URL, ensuring they always target the correct preview deployment.

Branch Management UI

3. Exploratory Testing & Smart Bug Diffing

Exploratory testing is no longer a "post-release" activity. All exploratory runs can now be executed against the branch-specific deployment.

Our agents are now smart enough to report only new bugs found on the feature branch compared to the default branch. This allows you to instantly see what UX, performance, accessibility, or internationalization issues were introduced by a specific PR – before they ever touch production.

4. QA Intelligence: Sliced by Branch

In the Atlas page, you can now filter results by branch to see exactly how a specific screen or flow was affected by a PR. This level of granularity allows teams to answer the questions that actually matter during code review:

  • "What user stories are breaking in this PR?"
  • "Are unrelated scenarios being affected by these changes?"

Seamless CI Integration

If you already have a CI pipeline that generates preview URLs, TestChimp fits right in. Simply pass that preview URL as the BASE_URL environment variable in your CI action, and your tests will execute against the live branch deployment with zero extra configuration.

Strategic Planning, Tactical Execution

While test authoring and execution are now branch-aware, we’ve intentionally kept Test Planning artifacts product-scoped.

Strategy should be stable. Planning artifacts continue to sync with the repo's default branch, ensuring your high-level test coverage goals remain consistent even as individual features are developed and tested in parallel branches.

The Future is Shift-Left

By moving QA participation closer to the development phase, you’re not just catching bugs – you’re preventing them from ever reaching the main branch. Branch-aware testing turns QA from a gatekeeper into a core part of the feature development engine.

UX Bug Traceability: Translating Bugs to Business Impact

  • Which bugs are slowing down your checkout flow?
  • Are there localization issues in onboarding causing drop-off?

Most QA setups fall short of answering such questions that matter to the business.

The Gap Between QA and Business Impact

Traditional QA workflows surface issues --- broken buttons, layout glitches, validation errors, performance slowdowns. But when leadership asks:

  • How is this affecting conversion?
  • Is onboarding friction hurting activation?
  • Which workflow is most at risk?

The connection between bugs and business outcomes is often missed entirely - resulting in QA being perceived as a cost center, than what it really is - revenue protection.

That's the gap we're addressing today by adding UX bug traceability to our QA intelligence layer.

Guided Exploration, Not Random Crawling

Our secret sauce: Our exploratory agents don't wander randomly.

They use your existing automation tests as guides. Because tests are already linked to scenarios (via structured code comments), that same traceability naturally extends to exploratory runs and their findings.

This means every discovered issue can be traced back to:

  • The scenario
  • The user story
  • The business objective behind it

Exploration becomes business-contextual --- not isolated.

UX Bug Traceability Linkage

Structured for Insight at Any Level

In TestChimp, user stories are organized in nested folders. That structure becomes powerful when paired with traceable exploratory results.

Insights roll up automatically:

  • By area of the application
  • By workflow
  • By product surface
  • By team ownership

You can zoom in to a single scenario or zoom out to understand impact across an entire product area.

UX Bug Traceability Screenshot

Beyond a Floating Bug List

Instead of maintaining a detached list of issues, you gain visibility into:

  • Which flows are degrading user experience
  • Which exact bugs are causing latency in key user journeys - that mater to your revenue
  • Where UX friction is tied to user retention

It's no longer just about "bugs found."

It's about translating them understanding what is hurting your revenue --- and prioritizing accordingly.

Test Planning as Code: Your Test Artifacts, Version-Controlled and Agent-Ready

We used to live in forms.

Historically, dropdowns and text fields were the default way we planned and managed work. But in the agentic era, the winning UX isn’t a fancy form. It’s plain, boring text.

We already see it everywhere. We use skills.md for upskilling agents. claude.md for context. Spec-based development in Cursor. But look at your test planning tools. Jira, Linear—they were built in a pre-AI era. They’re database-centric, form-heavy, and fundamentally hostile to agentic workflows.

Research shows test planning activities are still applied inconsistently, and that gap can lead to negative delivery and cost outcomes in software projects (planning activities in software testing process).

Traditionally, a test plan is a structured way to define test objectives, scope, risks, resources, and schedules—so teams can communicate what execution should accomplish (ISTQB on test plan purpose and content).

And modern testing standards treat planning as a continuous process across the lifecycle, not one-and-done documentation (ISO/IEC/IEEE 29119).

Shouldn’t test planning be as modern as coding?

Recent work suggests test artifacts can be managed more like software assets with explicit lifecycle concerns (test artifacts and lifecycle in software evolution).

And established testing guidance emphasizes requirements-based prioritization when deciding what to execute next (ISTQB test case prioritization).

That’s why we’ve reimagined test planning for the agentic era. We call it Test Planning as Code.


Plans as strongly typed markdown

In TestChimp, your plans live as strongly typed markdown files—user stories and test scenarios as .md files with YAML frontmatter, organized in folders and version-controlled alongside your codebase.

Test Scenario as Markdown

There are some pretty significant advantages to maintaining stories and scenarios as simple .md files.

At its core, a test plan defines test objectives, scope, risks, resources, and schedules—so execution stays aligned to what “done” means (ISTQB on test plan purpose and content).

First, they sync to your code repository. That means your coding and testing agents can read them and work on them directly. No proprietary API, no “export for AI”—just the same files your team already uses.

Second, you can organize them in a nested folder structure however you want. By area. By journey. By team. That structure gives agents broader context. They see related stories and linked scenarios, not just isolated tickets floating in a database.

This is what actually gets stored in your repo. No proprietary formats. No lock-in. Just plain markdown.


“I don’t want to manage status in a text editor”

Humans still need workflows. We need priorities, due dates, and assignees.

TestChimp layers those workflows on top of the files. You get the familiarity of a structured UI for human workflows—rich forms, status dropdowns, filters—without losing the benefits of file-first planning. The source of truth stays in the files; the platform makes them easier to work with.

User Story Form

And because TestChimp indexes everything, the AI can actually work with your plan. It can help write or refine a user story more accurately. It can suggest relevant test scenarios. It can even detail them out, grounded in your actual requirements.

Linked Scenarios


Linking tests is trivial

Once you have scenarios, linking tests is trivial. Just add a comment in your test code:

// @Scenario: Login - Invalid Credentials Error

No spreadsheets. No manual mapping. No juggling multiple tools.

Export to Git keeps your test plan in the repo—stories and scenarios live under a path you choose, with full history and pull-request workflows. Your agents and your CI see the same files.

Export to Git


Coverage at any granularity

As tests run, coverage insights update automatically. And because your stories are organized in folders, you can see coverage at any granularity—per story, per area, per component.

If you’re working in a team where different groups own different parts of the system, you already know how useful this is.

Requirement Traceability

You can finally answer the question: Which scenarios are due next week, ready for testing, but still missing coverage? No spreadsheet. No manual roll-up. Just select the folder, apply the filters, and look at the Insights tab.


Wrapping up

Test Planning as Code is a different take on where test artifacts should live and who should be able to use them. Files in the repo instead of rows in a database; workflows layered on for humans, and that same file structure giving agents the context they need. If that approach resonates—or you’re just curious how it works in practice—we’ve documented the full workflow in the Test Planning section: authoring user stories, authoring test scenarios, export to Git, and requirement traceability.

Requirement Traceability, Without the Spreadsheet Circus

Q: How do you currently get requirement traceability?
Which user stories and scenarios are covered by tests, and what’s failing?

A:
For most teams, it looks something like this:

User stories live in Jira.
Test cases live somewhere else.
The mapping between them lives in an Excel sheet that someone manually maintains.

That spreadsheet is periodically uploaded to a test management tool like PractiTest. Then test execution results are pushed via an API to get a view of coverage and failures.

It works—until it doesn’t.


The problem with today’s approach

This is how requirement traceability is typically achieved today: a hodgepodge of tools stitched together with process and hope.

  • Multiple sources of truth
  • Manually maintained spreadsheets that inevitably go stale
  • Fragile workflows that break as teams and test suites scale

No single system actually owns the full picture. Instead, teams spend time keeping artifacts in sync rather than improving product quality.


A simpler model with TestChimp

In TestChimp, requirement traceability isn’t an afterthought. It’s built in.

You already author detailed user stories and break them down into meaningful test scenarios directly in the platform - with AI assistance that understands your product through your existing test scripts and documentation.

Linking tests to those scenarios is intentionally simple. In your test script, add a comment:

// @Scenario: <scenario title>

That’s it! TestChimp takes care of the rest:

  • Automatically links tests to scenarios
  • Tracks execution results across runs
  • Aggregates outcomes at scenario, story, and suite level

Requirement Traceability

You get clear, real-time dashboards that let you answer business relevant questions:

  • Which user stories are missing test coverage?
  • Which scenarios are currently failing?
  • Which tests are flaky or unstable?

All without juggling multiple tools or maintaining brittle Excel sheets.

One system, end to end

Instead of retrofitting traceability after the fact, TestChimp treats it as a first-class concept - connecting requirements, scenarios, and executions in one place.

  • No spreadsheets.
  • No manual syncing.
  • Just a single system that understands what you’re building, how it’s tested, and where the gaps are.
