io.github.orangehrm/orangehrm/testing

Reference for OrangeHRM's test layers — PHPUnit per-plugin testsuites declared in `phpunit.xml`, the test-DB lifecycle (`instance:create-test-db` builds a populated MySQL DB plus a `CoreFixtureService` dump that bootstrap restores per test), test base classes (`TestCase` for plain unit tests, `KernelTestCase` for tests that need the full framework + DI container, `EntityTestCase` for entity-only tests, `EndpointTestCase` and `EndpointIntegrationTestCase` for API endpoint tests with request mocking + exception expectations), the YAML fixture pattern (per-plugin `test/fixtures/<DaoName>.yml` + `TestDataService::populate($yamlPath)` in `setUp()`), Jest configuration for frontend unit tests (`@vue/cli-plugin-unit-jest/presets/typescript-and-babel`, `__tests__/` siblings), and Cypress for E2E (separate workspace under `src/test/functional/`). Use whenever the user is writing a test, deciding which base class to extend, debugging fixture loading, setting up the test DB, running a single test class, or trying to fig

io.github.exceptionless/Exceptionless/backend-testing

Use this skill when writing or modifying C# tests — unit tests, integration tests, or test fixtures. Covers xUnit patterns, AppWebHostFactory for integration testing, FluentClient for API assertions, ProxyTimeProvider for time manipulation, and test data builders. Apply when adding new test cases, debugging test failures, or setting up test infrastructure.

io.github.exceptionless/Exceptionless/frontend-architecture

Use this skill as the frontend entrypoint for the Svelte 5 app in ClientApp — adding routes, creating feature slices, writing Svelte components, applying TypeScript conventions, using shared UI/formatter components, handling accessibility, or adding frontend tests. The legacy Angular app still powers most of the current site in ClientApp.angular, but all new frontend development should be Svelte UI only unless the user explicitly asks for Angular or legacy UI changes.

The tester evaluates the authorization server, client application, and token handling for common misconfigurations that enable account takeover or unauthorized access. Activates for requests involving OAuth security testing, OIDC vulnerability assessment, OAuth2 redirect bypass, or authorization code flow testing.

Meta-skill that analyzes the Trail of Bits Testing Handbook (appsec.guide) and generates Claude Code skills for security testing tools and techniques. Use when creating new skills based on handbook content.

io.github.bluesky-social/atproto/testing

Testing practices for this monorepo — choosing between unit and end-to-end tests, where test files live, how tsconfig.test.json fits in, how to drive Playwright, to to write/adapt UI/end-to-end tests, and which test runner (vitest vs jest) to use. MUST be invoked BEFORE any code search or file reads whenever the user asks to add, write, or extend a test, add coverage, create a test file, set up testing in a new package, mentions vitest/jest, or refers to an existing `*.test.ts` file. Applies equally to unit tests and to end-to-end / UI tests — the skill routes to a Playwright-MCP-first discovery flow for the latter, which differs from normal code-search workflow.

io.github.android/skills/testing-setup

io.github.eduhub-org/eduhub/cursor-browser

Inspect UI via cursor-ide-browser (Cursor Browser tab); fall back to user-playwright if internal browser MCP is unavailable. Use for @Browser, open tab, layout checks, localhost — or when user explicitly asks for Playwright.
