Go testing patterns for production-grade code: subtests, test helpers, fixtures, golden files, httptest, testcontainers, property-based testing, and fuzz testing. Covers mocking strategies, test isolation, coverage analysis, and test design philosophy. Use when writing tests, improving coverage, reviewing test quality, setting up test infrastructure, or choosing a testing approach. Trigger examples: "add tests", "improve coverage", "write tests for this", "test helpers", "mock this dependency", "integration test", "fuzz test". Do NOT use for performance benchmarking methodology (use go-performance-review), security testing (use go-security-audit), or table-driven test patterns specifically (use go-test-table-driven).
[Pragmatic DDD Architecture] Guide for creating tests. Use when creating unit tests, integration tests, or understanding test conventions. Covers our tightly coupled stack: Vitest (unit, integration, ui projects), file naming, transactional database integration tests (txTest) with testcontainers/node-postgres/drizzle, mock patterns (createMock*RepoWithAssertions), and neverthrow Result assertions.
Generates production-grade JUnit 5 unit and integration tests in Java. Covers assertions, parameterized tests, lifecycle hooks, mocking with Mockito, and nested tests. Use when user mentions "JUnit", "JUnit 5", "@Test", "assertEquals", "Assertions", "Java unit test". Triggers on: "JUnit", "@Test", "assertEquals", "Java test", "unit test Java".
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".
E2E 단위 시나리오를 조합한 통합 테스트 시나리오를 md로 생성·관리·실행하는 스킬. "통합 시나리오", "e2e suite", "통합 테스트", "시나리오 조합", "e2e 통합", "전체 흐름 테스트" 키워드로 트리거.
Vertical-slice TDD for any production code. One test → one impl → repeat. Tests verify behavior through public interfaces, not internals. Use when implementing any feature, bugfix, or behavior change.
Test Go Gin APIs with httptest, table-driven tests, testcontainers. Use when writing tests for Gin handlers, services, middleware, or setting up integration and e2e tests.
Complete testing setup with Neon database branching, Playwright browser tests, integration tests, and unit tests. Isolated branches with automatic TTL cleanup.
Use when nestJS testing with unit tests, integration tests, and e2e tests. Use when building well-tested NestJS applications.
Testing patterns and best practices for unit, integration, and E2E testing.
A comprehensive guide for using Testcontainers for Go to write reliable integration tests with Docker containers in Go projects. Supports 62+ pre-configured modules for databases, message queues, cloud services, and more.
Comprehensive API testing patterns including contract testing, REST/GraphQL testing, and integration testing. Use when testing APIs or designing API test strategies.
