單元測試

Write integration and unit tests for this codebase. Generate test files following repo patterns. Use when adding tests, improving coverage, writing test cases, or creating test suites.

Use when testing web applications with visual verification - automates Chrome browser interactions, element selection, and screenshot capture for confirming UI functionality

. Use when writing tests, reviewing test coverage, or setting up testing.

Use to detect and remove cognitive biases from reasoning. Invoke when prediction feels emotional, stuck at 50/50, or when you want to validate forecasting process. Use when user mentions scout mindset, soldier mindset, bias check, reversal test, scope sensitivity, or cognitive distortions.

Generate test coverage reports showing which code paths are tested. Use to identify untested code and improve test coverage.

Use when investigating why something happened and need to distinguish correlation from causation, identify root causes vs symptoms, test competing hypotheses, control for confounding variables, or design experiments to validate causal claims. Invoke when debugging systems, analyzing failures, researching health outcomes, evaluating policy impacts, or when user mentions root cause, causal chain, confounding, spurious correlation, or asks "why did this really happen?"

Comprehensive E2E test of voice call pipeline - place call, verify auth flow, monitor transcripts/scores, verify report. Use when user says "test voice e2e", "run voice test", or "full voice test".

Extract and summarize test failures from logs. Use to quickly understand what tests failed and why.

Implements tasks from .plans/ directories by following implementation guidance, writing code and tests, and updating task status. Use when task file is in implementation/ directory and requires code implementation with comprehensive testing. Launches research agents when stuck.

Testing TDD & BDD - Atoll Tourisme. Use when writing tests, reviewing test coverage, or setting up testing.

Measure test coverage and identify untested code. Use when assessing test completeness.

Place Twilio test calls. Use when user invokes /test-twilio.

Use when you need to empirically test whether hypothesized symmetries actually hold in your data or model. Invoke when user mentions testing invariance, validating equivariance, checking if symmetry assumptions are correct, debugging symmetry-related model failures, or needs data-driven validation before committing to equivariant architecture. Provides test protocols and metrics.

Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first

Regel 07: Testing. Use when writing tests, reviewing test coverage, or setting up testing.

Generate comprehensive test plans, manual test cases, regression test suites, and bug reports for QA engineers. Includes Figma MCP integration for design validation.

MANDATORY - INVOKE BEFORE writing ANY test code (def test_*, class Test*). Prevents brittle tests. Read this skill first, then write tests.

Debug and fix CI/CD pipeline failures. Analyze workflow logs, identify issues, and apply fixes. Use when CI is failing, build errors occur, tests fail in CI, or pipeline is broken.

WCAG 2.1 AA/AAA accessibility compliance specialist for ARIA attributes, keyboard navigation, screen reader testing, color contrast validation, semantic HTML, and automated a11y testing with axe-core/

Validate that code actually works by executing targeted tests, tracing failures, and prescribing fixes with evidence.
