testing

Writing unit tests with pytest involves creating functions that assert expected behavior. This skill provides structural patterns, fixtures for environment setup, and mocking techniques to isolate dependencies and validate Python code deterministically.

Testing TypeScript components with Vitest involves importing components and rendering them within test blocks. This skill provides examples for React and Vue component testing, covering mocks and async tests to validate UI behavior reliably.

Setting up fixtures and mocks for integration testing uses pytest's fixture system to manage state and dependency isolation. This skill demonstrates configuring test environments and mocking external calls to ensure deterministic validation.

Yes, you can test async Python API endpoints and HTTP routes. This skill covers async testing and provides specific HTTP testing patterns using Litestar to validate endpoint request and response cycles correctly.

Enforcing code coverage targets involves configuring your test runner to track executed lines and fail builds below a threshold. This skill guides on achieving and enforcing coverage metrics for both Vitest and pytest test suites.

Async Vitest tests often fail due to improper mock resolution or missing await keywords. This skill provides expert guidance on writing async tests and isolating dependencies correctly to ensure reliable and deterministic test execution.
