What are some common mistakes when testing React hooks?
Some common mistakes include not testing the hook's behavior in isolation, ignoring cleanup effects, and not using the right testing utilities.
Can you explain why testing hooks in isolation is important?
Testing hooks in isolation helps ensure that the hook's logic works independently, making it easier to identify issues.
What testing utilities should I use for React hooks?
You can use utilities like React Testing Library and Jest, which provide helpful functions for testing hooks effectively.
How do I handle cleanup effects in my tests?
You should ensure that any side effects are properly cleaned up in your tests by using the cleanup
function from React Testing Library.
Are there any specific examples of mistakes to avoid?
Yes, avoid assuming that hooks will always behave the same way in tests as they do in production, and always mock dependencies properly.
