.NET Testing Basic Skills Overview and Guidance Hub. Triggered when users ask general testing questions such as "How to write .NET tests", "Introduction to .NET testing", "What testing tools are needed", "Testing best practices", "Learn testing from scratch", etc. It will recommend suitable sub-skill combinations based on specific needs, covering 19 basic skills including testing fundamentals, test data, assertions, mocking, special scenarios, etc. Keywords: dotnet testing, .NET testing, testing introduction, how to write tests, testing best practices, unit test, unit testing, xunit, 3A pattern, FIRST principles, assertion, assertion, mock, stub, NSubstitute, test data, AutoFixture, Bogus, validator, FluentValidation, TimeProvider, IFileSystem, code coverage, ITestOutputHelper, test naming

Enforces TDD best practices across teams with AI-assisted testing and modern frameworks. Use PROACTIVELY for TDD implementation and governance.
Write unit tests, component tests, and integration tests for AiderDesk using Vitest and React Testing Library. Use when creating new tests, adding test coverage, configuring mocks, setting up test files, or debugging failing tests.
Read this skill to write, generate, or add test code. Trigger when: (1) user asks to write, add, create, or generate tests of any kind (unit tests, integration tests, API tests, E2E tests, Playwright tests, Vitest tests); (2) user has code with missing or zero tests and wants coverage; (3) user just implemented a new service, endpoint, feature, or module and needs tests for it; (4) user refactored code and wants to verify nothing broke with tests; (5) user wants to improve or expand existing test coverage. This skill produces complete, pyramid-shaped test suites — reads the code, selects only the necessary layers (unit/integration/API/E2E), and generates every file needed (schema tests, service tests, factories, helpers, cleanup utilities, spec files) following strict Vitest and Playwright patterns. Skip this skill when debugging failing tests, asking how to use testing APIs or tools, explaining testing concepts, configuring test runners, reviewing existing test code, or migrating between test frameworks.
Use this skill when deciding what to test, choosing between test types, designing a testing strategy, or balancing test coverage. Triggers on test pyramid, unit vs integration vs e2e, contract testing, test coverage strategy, TDD, BDD, testing ROI, and any task requiring testing architecture decisions.
Writes, reviews, and improves Swift Testing code using modern APIs and best practices. Use when reading, writing, or reviewing projects that use Swift Testing.
React component and hook testing patterns with Testing Library and Vitest. Use when writing tests for React components, custom hooks, or data fetching logic. Covers component rendering tests, user interaction simulation, async state testing, MSW for API mocking, hook testing with renderHook, accessibility assertions, and snapshot testing guidelines. Does NOT cover E2E tests (use e2e-testing) or TDD workflow enforcement (use tdd-workflow).
Pre-commit code quality review workflow. Use before committing changes to verify code quality, security, testing coverage, and adherence to project conventions. Supports both automated checking and interactive review modes.
