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,
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.
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.
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.
Write and run tests for JS/TS projects. Handles unit tests with Vitest and React Testing Library directly. Delegates E2E and browser testing to /webapp-testing. Use when writing tests, adding coverage, debugging test failures, or running test suites.
Vitest test runner for JavaScript and TypeScript. Fast, modern alternative to Jest. Vite-native, ESM support, watch mode, UI mode, coverage, mocking, snapshot testing. Use when setting up tests for Vite projects, migrating from Jest, or needing fast test execution.
Use when implementing well-scoped Python tasks with clear requirements, writing unit tests, and producing documented code for senior-developer review.
Get best practices for MSTest 3.x/4.x unit testing, including modern assertion APIs and data-driven tests
Get best practices for XUnit unit testing, including data-driven tests
Test-Driven Development workflow enforcement with RED-GREEN-REFACTOR cycle. Use when implementing features test-first or improving test coverage.
Creates integration test cases for .NET data access artifacts during Oracle-to-PostgreSQL database migrations. Generates DB-agnostic xUnit tests with deterministic seed data that validate behavior consistency across both database systems. Use when creating integration tests for a migrated project, generating test coverage for data access layers, or writing Oracle-to-PostgreSQL migration validation tests.
Rust testing patterns including unit tests, integration tests, async testing, property-based testing, mocking, and coverage. Follows TDD methodology.
