Can I use this for mocking external APIs?

Absolutely. The skill provides standardized templates for using unittest.mock in Python and jest.mock in JavaScript to isolate your code from external dependencies.

How does the skill handle code coverage?

It integrates with pytest-cov and Jest's native coverage tools to measure line, branch, and function coverage, defaulting to an 80% success threshold.

Which programming languages are supported by this skill?

This skill specifically supports Python using the pytest framework and JavaScript/TypeScript using the Jest framework.

Does it support testing for React components?

Yes, it includes patterns for @testing-library/react to facilitate component rendering and async data testing in JavaScript environments.

Is it compatible with CI/CD pipelines?

Yes, it provides configuration examples for GitHub Actions and export formats like JUnit XML and JSON for automated reporting.
