@jest/globals
Advanced tools
Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple. It's similar to @jest/globals in providing a testing structure (describe and it blocks), but it requires additional libraries like Chai for assertions and Sinon for spies, mocks, and stubs.
Chai is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework. It's similar to the assertion part of @jest/globals, offering a range of assertions via expect, should, and assert interfaces. However, it does not provide test runner or mocking capabilities.
Sinon provides standalone test spies, stubs, and mocks for JavaScript. Works with any unit testing framework. It's similar to the mocking functionality of @jest/globals but is focused solely on the aspect of mocking, without an integrated test runner or assertion library.
