When should I use Sinon instead of Jest?

You might choose Sinon when you need to create spies, mocks, or stubs for functions, especially in a more complex testing scenario.

What are the main differences between Sinon and Jest?

Sinon is primarily focused on creating spies, mocks, and stubs, while Jest is a complete testing framework that includes assertions, mocking, and more.

Can I use Sinon with Jest?

Yes, you can use Sinon alongside Jest, but Jest has its own mocking capabilities that might be sufficient for most cases.

Which one is better for unit testing?

It depends on your needs. Jest is great for a full testing suite, while Sinon is excellent for specific mocking needs.

Are there any performance differences between them?

Generally, Jest is optimized for performance and can run tests in parallel, while Sinon may require more setup for complex scenarios.
