What are some common issues faced in React testing?
Some common issues include shallow rendering problems, asynchronous testing challenges, and mocking dependencies.
Can you explain shallow rendering and why it's problematic?
Shallow rendering allows you to render a component without rendering its children, which can lead to incomplete tests.
How can I handle asynchronous testing in React?
You can use tools like Jest's async/await or the waitFor
utility from React Testing Library to manage async tests.
What are some best practices for mocking dependencies?
Best practices include using libraries like Jest for mocking, ensuring mocks are reset between tests, and keeping mocks simple.
