Testing & QA
Diagnosing bugs
A disciplined debugging loop for complex issues.
Red-green-refactor TDD
Test-driven development with the red, green, refactor loop.
Find bugs (Sentry)
Find bugs, vulnerabilities and code quality issues.
Test generation flow
Generates a useful test suite for a module: behaviours, edge cases, tests and a mutation check.
Test gap finder
Finds untested behaviour that matters and suggests the most valuable tests. Use to plan testing.
E2e test writer
Writes end-to-end browser tests for key user flows with stable selectors and no fixed waits. Use when adding Playwright or Cypress tests.
Test data generator
Generates realistic, safe test data for forms, databases and APIs, including edge cases. Use when you need fixtures or sample records.
Coverage gap finder
Reads a coverage report and the code to find the untested behaviour that matters most. Use to decide what to test next.
Regression checklist
Builds a regression checklist for a release from the changes made and the areas they could affect. Use before shipping.
Systematic debugging
Find the root cause with a structured method before proposing a fix.
Test-driven development
Write the failing test first, then the code, then clean up.
Verification before completion
Run the checks and show the evidence before saying work is done.
Test writer
Writes and runs tests for new or changed code in the project's own style. Use after adding a feature or fixing a…
Web app testing
Test local web apps with Playwright: screenshots, logs and UI checks.
Flaky test triage
Finds why a test passes sometimes and fails sometimes, and suggests the smallest fix. Use when CI is flaky.
Write unit tests
Writes clear unit tests covering normal, edge and error cases using the project's existing test style. Use when asked to add tests.
Bug reproduction
Turns a vague bug report into exact reproduction steps and a failing test. Use when a bug is reported without clear steps.
Test plan writer
Writes a practical test plan for a feature: scenarios, edge cases, data and risks. Use before testing or releasing a feature.
