How can I improve performance when using Jest for mocking?
To improve performance in Jest when mocking, consider using manual mocks instead of automatic ones, as they can be more efficient.
What are manual mocks and how do I create them?
Manual mocks are custom implementations of modules that you create in a __mocks__ directory. You can define them to return specific values.
Are there any best practices for using manual mocks?
Yes, keep your mocks simple, avoid unnecessary complexity, and ensure they closely resemble the actual implementation to prevent issues.
Can I use Jest with TypeScript for mocking?
Absolutely! Jest works well with TypeScript. Just ensure you have the necessary type definitions installed.
