How to test asynchronous operations in React components using Jest and React Testing Library?

Use async/await and waitFor functions.

Use timers to simulate asynchronous calls.

Directly test the asynchronous code.

Ignore asynchronous operations during testing.

What's the best approach for testing custom hooks in React?

Isolate and test the hook's logic directly.

Use shallow rendering for the hooks.

Test the hook within a component.

Don't test custom hooks.

How to effectively test React components using a mocking library?

Mock everything for simplicity.

Avoid mocking in unit testing.

Isolate dependencies and mock external calls.

Test with real dependencies always.

What's the role of a snapshot testing in React component testing?

Verify UI structure hasn't unexpectedly changed.

Handle asynchronous operations.

Test functionality thoroughly.

Replace unit testing completely.
