Sinon.js vs Jest: Which is better for testing?

What are the main differences between Sinon.js and Jest?

Sinon.js is primarily a library for creating spies, mocks, and stubs, while Jest is a complete testing framework that includes built-in mocking capabilities.

Can I use Sinon.js with Jest?

Yes, you can use Sinon.js with Jest, but Jest has its own mocking functions that might be more convenient.

Which one should I choose for my project?

It depends on your needs. If you want a full testing framework with built-in features, go for Jest. If you need advanced mocking, consider Sinon.js.

Are there any performance differences between the two?

Jest is generally faster due to its parallel test execution and built-in optimizations, while Sinon.js may add overhead if used extensively.
