How can I improve the performance of my React Native tests?

To improve the performance of your React Native tests, consider using tools like Jest for unit testing and optimizing your test setup.

What specific optimizations can I make in Jest?

You can optimize Jest by using the --runInBand option to run tests serially, which can reduce overhead, and by mocking heavy dependencies.

Are there any best practices for writing efficient tests?

Yes, focus on writing small, isolated tests, avoid unnecessary re-renders, and use shallow rendering when possible.

How can I measure the performance of my tests?

You can use Jest's built-in performance metrics or integrate tools like React Native Performance to track test execution times.
