Find the perfect capability for your agent.
Use when creating new skills, editing existing skills, or verifying skills work before deployment - applies TDD to process documentation by testing with subagents before writing, iterating until bulletproof against rationalization
Fix failing tests based on failure reports, verify fixes, and iterate until all tests pass. This skill should be used after test-executor generates failure reports, providing systematic debugging and fixing strategies that work with any framework or language.
Runs tests for Spring Boot modules with proper Java version handling. Use when testing code changes, debugging test failures, or verifying module functionality.
Jest and React Native Testing Library patterns. Use when writing component tests.
Test Temporal workflows with pytest, time-skipping, and mocking strategies. Covers unit testing, integration testing, replay testing, and local development setup. Use when implementing Temporal workflow tests or debugging test failures.
Write reliable Playwright E2E tests following official best practices. Prioritizes user-facing locators, web-first assertions, and test isolation. NEVER mock application data. Avoid explicit waits unless component-specific. Use when writing, reviewing, or debugging Playwright tests.
Comprehensive guide to Rust automated testing covering unit, integration, and documentation tests. Includes practical patterns for async testing, property-based testing with proptest, mocking strategies using traits, and essential testing tools (cargo-nextest, criterion, tarpaulin). Emphasizes FIRST principles and CI/CD integration. Use this when: setting up new Rust projects, establishing testing standards for teams, improving existing test suites, implementing TDD workflows, or learning Rust testing ecosystem best practices. Particularly valuable for projects requiring high reliability and comprehensive test coverage.
Reproduce bugs and gather evidence for root cause analysis. Use when investigating a bug report to confirm reproduction and collect detailed information about the failure.
Comprehensive Python testing with pytest framework, including test creation, fixtures, parameterized tests, and test execution. Use when Claude needs to work with Python testing for creating new tests, modifying existing tests, working with fixtures and test configuration, running tests with specific options, or debugging test failures.
Generate comprehensive Pest test suites for Laravel projects including tests for controllers, services, Livewire components, commands, jobs, and models with proper describe blocks for organization, mocking setup, happy path and failure scenarios, RefreshDatabase trait, and coverage for all public methods. Use this skill when creating test files for new features, adding test coverage for controllers or services, writing tests for API endpoints, testing Livewire components, ensuring proper test structure with beforeEach and describe blocks, implementing mocking strategies, or writing dataset-driven tests. This skill applies when working on files in tests/Feature/ or tests/Unit/ directories, creating Pest test files, or ensuring comprehensive test coverage.
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
Analyze test failures and suggest fixes for Feature Swarm verification. Use when tests fail during the verification phase to diagnose root cause and determine if automatic recovery is possible.
Use when extracting structured data from websites using Playwright MCP tools, when handling login/authentication flows, when crawling paginated content, or when building scrapers that navigate dynamic SPAs with tabs, accordions, or React/HeadlessUI components
Standard procedure for creating reusable pytest fixtures in conftest.py files for the airline-discount-ml project.
Web/React interrogation using HAR + Playwright trace and endpoint mapping (behavior-first when sourcemaps absent).
Use when creating new skills, editing existing skills, or verifying skills work before deployment - applies TDD to process documentation by testing with subagents before writing, iterating until bulletproof against rationalization
Complete TDD workflow for creating comprehensive failing test suites across all architectural layers (entities, use cases, services, APIs, E2E) using Vitest, Playwright, and Testing Library. Mandatory Context7 consultation for latest testing patterns.
Generates vitest.config.ts for unit testing configuration. Configures Vitest with Vue, TypeScript support, coverage thresholds, and test environment settings.
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
Comprehensive testing workflow for password generator applications. Use when creating, running, or debugging tests for password generation functionality.
