Use when writing unit/integration tests for Vite projects - provides Vitest configuration, test APIs, mocking patterns, and coverage setup
Clarify intent, propose 2-3 approaches, embedded grill to stress-test the chosen path. Use before any creative work — new features, components, behavior changes, design questions. Mockup-only requests use mockup quick-mode (no spec/plan ceremony).
Best practices for writing JavaScript/TypeScript tests using Jest, including mocking strategies, test structure, and common patterns.
Test React components with Testing Library patterns. Covers queries (getBy/findBy/queryBy), user-event interactions, async testing (findBy vs waitFor), accessibility testing, and MSW integration for API mocking. Use when: testing React components, simulating user interactions, testing forms, mocking API calls with MSW, or writing accessible tests. Keywords: testing-library, react testing library, getByRole, user-event, waitFor, MSW, screen.
WordPress plugin and theme testing with PHPUnit integration tests, WP_Mock unit tests, PHPCS coding standards, and CI/CD workflows
Use this skill when writing Go tests with stretchr/testify, implementing TDD workflows, creating mocks, or organizing test suites. Covers assert vs require patterns, interface mocking, table-driven tests, and the red-green-refactor cycle.
Generate and validate Apex test classes with TestDataFactory patterns, bulk testing (251+ records), mocking strategies, assertion best practices, and disciplined test-fix loops. Use this skill when creating new Apex test classes, improving test coverage, debugging and fixing failing Apex tests, running test execution and coverage analysis, or implementing testing patterns for triggers, services, controllers, batch jobs, queueables, and integrations. Triggers on *Test.cls, *_Test.cls files, sf apex run test workflows, coverage reports, test-fix loops. Do NOT trigger for production Apex code (use platform-apex-generate) or Jest/LWC tests.
Write and run Go tests using the built-in testing package with table-driven tests, subtests, and mocking via interfaces. Use when writing Go tests or setting up test infrastructure.
Generates Jest unit and integration tests in JavaScript or TypeScript. Covers mocking, snapshots, async testing, and React component testing. Use when user mentions "Jest", "describe/it/expect", "jest.mock", "toMatchSnapshot". Triggers on: "Jest", "expect().toBe()", "jest.mock", "snapshot test", "JS test", "React test".
Test authenticated routes in the your project using cookie-based authentication. Use this skill when testing API endpoints, validating route functionality, or debugging authentication issues. Includes patterns for using test-auth-route.js and mock authentication.
Create factory fixture patterns for customizable test setup with variations. Use when building reusable test fixtures with multiple configurations, creating parameterizable mocks, or implementing test data builders. Works with pytest fixtures, mock objects, and test utilities. Enables DRY test setup while maintaining flexibility for edge cases.
Comprehensive testing patterns for Spring Boot applications including unit, integration, slice, and container-based testing with JUnit 5, Mockito, Testcontainers, and performance optimization. Use when implementing robust test suites for Spring Boot applications.
