Which programming languages does this skill support?

The skill includes specific framework recommendations and implementation templates for JavaScript/TypeScript (Vitest, Jest, Playwright), Python (Pytest), and Go.

Does it support mocking external APIs?

Absolutely. It provides specific strategies and code examples for mocking external services using tools like MSW (Mock Service Worker), factory functions, and fixtures.

Can it help with end-to-end (E2E) testing?

Yes, it includes specialized templates and tool recommendations like Playwright, Cypress, and Selenium for testing critical user journeys.

How does it help with code coverage?

It provides a defined coverage strategy with specific thresholds (e.g., 80% global, 95% core) and checklists to ensure business logic and edge cases are fully covered.
