Create or update pytest coverage for the tic-tac-toe project, including win/draw detection, move validation, bot legality/optimality, and mixed human/bot turn flow. Use when adding or editing tests under the tests/ directory.
Run the CPython regression test suite in this repo via scripts/run_cpython_tests.sh with parallel execution, enforce a per-test timeout, capture output to cpython_full_test_run.log, and summarize failures from that log.
Use when implementing features or refactoring with TDD - enforces writing ONE test at a time, implementing minimal code to pass, then repeating, preventing batch test writing that defeats incremental design discovery
A skill for setting up and running end-to-end browser tests using Playwright. It includes guidance on project setup, the Page Object Model, user flow testing, visual regression, cross-browser configuration, and CI integration. Use this when a user wants to implement browser-based E2E testing.
Implement Advent of Code solutions using Test-Driven Development. Generates test cases from puzzle examples, writes failing tests first, implements solutions incrementally, and iterates until all tests pass. Use when solving AoC puzzles, implementing solutions with TDD, or when user mentions test-driven development or writing tests.
Write end-to-end tests with Playwright for web applications. Includes fixtures, page objects, test templates, visual regression testing, and accessibility audits.
Executes Unity tests and checks coverage. MUST use proactively after implementing features, fixing bugs, or modifying Domain/Application layer code. Also triggers on "test", "テスト".
Write Vitest tests with describe/test blocks, expect assertions, vi mocking, async testing, and parameterized tests. Use when creating or modifying test files.
TDD for process documentation - test with subagents before writing, iterate until bulletproof
Unit testing patterns with xUnit, Moq, and FluentAssertions including AAA pattern, naming conventions, mocking, and edge case coverage. Use when writing or reviewing unit tests.
Follow TDD cycle (RED-GREEN-REFACTOR) writing failing tests first, covering edge cases and error states, using explicit fixtures, and maintaining fast test suites with coverage gates. Use this skill when writing unit tests, integration tests, contract tests, or any test code in test files. Applies to test directories, spec files, test runners (Jest, Vitest, pytest), mocking strategies, regression prevention, and ensuring statement/branch coverage thresholds that block merges when dropped.
Playwright 기반 TDD 개발을 지원합니다. 테스트 작성, 실행, 디버깅을 자동화하고 테스트가 통과할 때까지 반복 개발합니다. 사용자가 "TDD로 개발", "Playwright 테스트 작성", "테스트 통과시켜"와 같은 요청을 할 때 사용합니다.
Comprehensive guide to Rust testing best practices, including structure, unit vs integration testing, and specialized patterns for Axum/Tower applications.
Design test strategy with concrete test cases. Use before writing tests.
Self-feedback review loop to verify implementation matches specification. Use with --mode quick/standard/thorough to control review depth. Default is thorough (3 consecutive passes). (user)
Run, debug, and structure tests for this Go project (unit + integration), including generation prerequisites. Use when changing domain logic, repositories, HTTP handlers, or migrations.
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
Develop, test, and maintain the Paracle framework codebase. Use when implementing features, fixing bugs, writing tests, or refactoring framework code.
