Use when writing unit tests, adopting Swift Testing framework, making tests run faster without simulator, architecting code for testability, testing async code reliably, or migrating from XCTest - covers @Test/@Suite macros,
Write tests using Vitest and React Testing Library. Use when creating unit tests, component tests, integration tests, or mocking dependencies. Activates for test file creation, mock patterns, coverage, and testing best practices.
Provides comprehensive guidance for Jest testing framework including test writing, matchers, async testing, mocking, snapshots, configuration, and CLI. Use when the user asks about Jest, needs to write JavaScript/TypeScript tests, mock dependencies, or configure Jest for projects.
Comprehensive test automation specialist covering unit, integration, and E2E testing strategies. Expert in Jest, Vitest, Playwright, Cypress, pytest, and modern testing frameworks. Guides test pyramid design, coverage optimization, flaky test detection, and CI/CD integration. Activate on 'test strategy', 'unit tests', 'integration tests', 'E2E testing', 'test coverage', 'flaky tests', 'mocking', 'test fixtures', 'TDD', 'BDD', 'test automation'. NOT for manual QA processes, load/performance testing (use performance-engineer), or security testing (use security-auditor).
General testing best practices and guidelines for writing comprehensive, maintainable tests across different testing frameworks and languages.
Tests applications using the Pest 4 PHP framework. Activates when writing tests, creating unit or feature tests, adding assertions, testing Livewire components, browser testing, debugging test failures, working with datasets or mocking; or when the user mentions test, spec, TDD, expects, assertion, coverage, or needs to verify functionality works.
Testing frameworks for web, mobile, API, and unit testing
Expert blueprint for testing patterns using GUT (Godot Unit Test), integration tests, mock/stub patterns, async testing, and validation techniques. Covers assert patterns, signal testing, and CI/CD integration. Use when implementing tests OR validating game logic. Keywords GUT, unit test, integration test, assert, mock, stub, GutTest, watch_signals, TDD.
Execute and manage Rust tests including unit tests, integration tests, and doc tests. Use when running tests to ensure code quality and correctness.
Testing best practices for the frontend. Emphasizes E2E tests over unit tests, minimal mocking, and testing behavior over implementation details. Use when writing tests or reviewing test code.
Use when writing or reviewing tests for Python behavior, contracts, async lifecycles, or reliability paths. Also use when tests are flaky, coupled to implementation details, missing regression coverage, slow to run, or when unclear what tests a change needs.
Configure Bun's built-in test runner with Jest-compatible APIs. Use when setting up testing infrastructure, writing unit/integration/snapshot tests, migrating from Jest, or configuring test coverage. 3-10x faster than Jest.
