testcontainers-python specialist. Covers all container modules (PostgreSQL, MySQL, MongoDB, Redis, Kafka, RabbitMQ, MinIO, Elasticsearch, LocalStack), GenericContainer, wait strategies, Docker Compose, networks, pytest fixtures, and CI/CD integration. USE WHEN: user mentions "testcontainers", "docker in tests", "real database in tests", "test with real postgres/redis/kafka", asks about container fixtures or Docker-based testing. DO NOT USE FOR: Spring Boot testcontainers (Java) - use `spring-boot-integration`; Mocking HTTP - use `fastapi-testing`; Pure pytest patterns - use `pytest`
Unit testing patterns for isolated business logic tests — AAA pattern, parametrized tests (test.each, @pytest.mark.parametrize), fixture scoping (function/module/session), mocking with MSW/VCR at network level, and test data management with factories (FactoryBoy, faker-js). Use when writing unit tests, setting up mocks, structuring test data, optimizing test speed, choosing fixture scope, or reducing test boilerplate. Covers Vitest, Jest, pytest.
Set up performance benchmarks and CodSpeed harness for a project. Use this skill whenever the user wants to create benchmarks, add performance tests, set up CodSpeed, configure codspeed.yml, integrate a benchmarking framework (criterion, divan, pytest-benchmark, vitest bench, go test -bench, google benchmark), or when the user says 'add benchmarks', 'set up perf tests', 'create a benchmark', 'benchmark this', or wants to measure performance of their code for the first time. Also trigger when the optimize skill needs benchmarks that don't exist yet.
Generate bug triage prep notes from One Horizon bug data. Use when asked "prepare bug triage", "summarize open bugs", or "prioritize defects for review". Requires One Horizon MCP.
Enforces a disciplined Red-Green-Refactor (TDD) workflow in TypeScript/Node.js. Use this whenever creating new features, fixing bugs, or migrating logic to ensure high-quality, verifiable implementations.
Spring Boot testing fundamentals including @SpringBootTest, slice tests, MockMvc, mocking with @MockBean, test configuration, and testing utilities. For integration tests with Testcontainers, see spring-boot-integration. USE WHEN: user mentions "spring boot test", "mockmvc", "@WebMvcTest", "@DataJpaTest", asks about "@SpringBootTest", "@MockBean", "spring test", "controller test", "repository test" DO NOT USE FOR: Unit tests - use `junit` with Mockito; Integration tests with real DB - use `spring-boot-integration`; REST API clients - use `rest-assured`; E2E tests - use Selenium
Integration patterns for the GitHub Accessibility Scanner Action (github/accessibility-scanner). Teaches agents how to detect scanner presence, parse scanner-created issues, correlate findings with local scans, and track Copilot-assigned fix status.
Severity scoring, scorecard computation, confidence levels, and remediation tracking for web accessibility audits. Use when computing page accessibility scores (0-100 with A-F grades), tracking remediation progress across audits, or generating cross-page comparison scorecards.
Use this skill to monitor a deployed URL for regressions after deploys, merges, or dependency upgrades.
Graph-informed mutation testing triage. Parses codebases with Trailmark, runs mutation testing and necessist, then uses survived mutants, unnecessary test statements, and call graph data to identify false positives, missing test coverage, and fuzzing targets. Use when triaging survived mutants, analyzing mutation testing results, identifying test gaps, finding fuzzing targets from weak tests, running mutation frameworks (including circomvent and cairo-mutants), or using necessist.
Advises on testing approach — when to unit test vs integration test, coverage goals, and test organization. Use when writing tests or planning test strategy.
Minimal multimodal embedding smoke test for Model Studio VL embedding models.
