How to write effective unit tests for React components with Vitest?
I'm setting up testing for my React app using Vitest + React Testing Library. I'm not sure about best practices:
- Should I test implementation details (internal state) or only behavior?
- How do I test components that make API calls?
- When should I use
vi.mock()?
Looking for practical examples, not just "test behavior not implementation."
