FAQPage Schema

What is the best way to structure JavaScript and TypeScript tests?▼

The best way to structure JavaScript and TypeScript tests is using the Testing Trophy philosophy, which prioritizes integration tests to maximize confidence over implementation details and balances unit and E2E tests.

How do I write integration tests for React components?▼

To write integration tests for React components, focus on testing behavior rather than implementation details and use accessibility-first DOM query strategies to interact with elements exactly as users would.

When should I use mocking in JavaScript testing?▼

You should use mocking in JavaScript testing pragmatically at system boundaries, isolating external dependencies like network requests to ensure your tests remain reliable and focused on your own code's logic.

Does this testing approach work with any JavaScript testing framework?▼

Yes, this testing approach works with any JavaScript and TypeScript testing framework because it provides framework-agnostic principles for writing tests, DOM query strategies, and mocking techniques.

How do I choose between unit, integration, and E2E tests?▼

Choose between unit, integration, and E2E tests by applying the Testing Trophy model, which recommends prioritizing integration tests for the highest confidence-to-effort ratio while reserving unit and E2E tests for specific edge cases.
