Testing plugins

Decide what kind of test a change needs, then write it with testkit: a migrated Postgres database per test, in-process HTTP against the real app, and assertions on outbound calls

AI-native E2E testing orchestration CLI with visual evidence capture and live dashboard

1 skill

Acts as a senior QA engineer: scans your codebase, runs your app, and generates + runs disciplined Playwright e2e tests. Systematic coverage (happy/negative/edge/boundary/worst-case/authorization) with a blocking safety gate that never touches production.

1 skill

Collects and displays JUnit XML test reports

1 skill

QAIA scoring: read-only quality scoring (ISTQB 10-dimension rubric, /20) and a PASS/CONCERNS/FAIL/WAIVED release-readiness gate over the standardized run manifest. Scores only - never edits test content.

1 skill

Turns a list of features into a verified-red test harness: boundary contracts, table-driven tests, and a red check that proves each test fails for the right reason. Writes tests only — never production code.

1 skill

Run tests with coverage and baseline tracking (pytest, with JS/TS support planned)

1 agent

Diagnose slow pytest suites, profile with pyinstrument, apply targeted fixes, and produce a performance report

1 skill

Scaffold unit tests for functions and classes, detecting the project's test framework automatically

Node-tap and Testcontainers integration expertise: container-based testing, test lifecycle, service orchestration, and best practices for Node.js

1 skill

Fastify testing expertise with node-tap: unit tests, integration tests, route testing, plugin testing, and best practices

1 skill

Universal test coverage methodology for SwiftUI apps. Focuses on user outcomes over code-coverage metrics through end-to-end journey validation, cross-platform workflows, and real service integration (SwiftData + CloudKit, iOS ↔ macOS).

1 skill

AI-driven playtesting that navigates scenes, tests interactions, and reports issues

1 skill

Expert test engineer agent for comprehensive test suite design and implementation

1 agent

Guides systematic test case design using established testing techniques

1 skill

Add stable data-testid attributes that serve two jobs at once — selectors that survive refactors, and identity: an inspected DOM node greps straight back to the component that rendered it, with no second attribute. Detects the project's existing attribute name, naming convention, and test-runner config before editing; framework-agnostic (React, Vue, Angular, Svelte, Solid, web components, server-side templates). Also does the reverse lookup: inspected HTML to source file.

Red-green-refactor TDD cycle — write a failing test, make it pass, clean up.

1 command

Browser automation — writes and executes Playwright scripts for end-to-end testing and UI verification

1 skill

Vitest testing skill derived from official docs, maintained by Vitest team lead Anthony Fu.

1 skill

Adversarial test pass: write tests that try to falsify a change, keep only the ones that catch real defects.

스킬·플러그인·MCP 설치 후 "됐는지 모르겠다"를 증거 기반으로 검증해 판정합니다. "설치 됐는지 확인해줘", "이거 작동하는 거야?" 같은 요청에 사용.

1 skill

Test-driven development applied pragmatically in the classical (Detroit) style: the iron law of a failing test first, red-green-refactor, testing behaviour rather than implementation (the unit is a behaviour or module, not a class), the test-double ladder that prefers real objects and in-memory implementations over stubs and mocks, state verification over interaction verification, keeping in-memory implementations faithful through contract tests, and the inner-loop scope of TDD, with TypeScript specifics. Composable with your own conventions.

1 skill

Testing strategy applied pragmatically, the macro view above the inner TDD loop: the portfolio idea, the shapes (the pyramid, the practical test pyramid, the testing trophy, the ice-cream cone anti-pattern), the tiers (unit, integration, contract, end-to-end, acceptance), the size-versus-scope distinction from Software Engineering at Google, consumer-driven contract testing, coverage as a signal rather than a target, and flaky tests, with TypeScript specifics. Composable with your own conventions.
