What are some common mistakes in testing React hooks?

Some common mistakes include not mocking dependencies, ignoring cleanup, and not testing edge cases.

Can you explain why mocking dependencies is important?

Mocking dependencies helps isolate the hook's behavior, ensuring that tests focus on the hook itself rather than external factors.

What about cleanup? Why is that necessary?

Cleanup is crucial to prevent memory leaks and ensure that tests do not affect each other, leading to false positives or negatives.

How can I effectively test edge cases?

You can test edge cases by simulating various scenarios, such as unexpected inputs or state changes, to ensure robustness.
