What are the best practices for using Sinon in testing?

Some best practices for using Sinon include using spies to monitor function calls, stubs for controlling function behavior, and mocks for simulating complex dependencies.

Can you give an example of how to use a spy with Sinon?

Sure! You can create a spy like this: const mySpy = sinon.spy(); mySpy(); console.log(mySpy.called); // true.

What’s the difference between a stub and a mock?

A stub is used to replace a function with a predefined behavior, while a mock is an object that verifies interactions with it.

How do I integrate Sinon with Mocha?

You can integrate Sinon with Mocha by requiring Sinon in your test file and using it alongside your test cases to create spies, stubs, or mocks.
