How do I use Sinon.js for testing?
An example of an AI chatbot conversation about using Sinon.js for testing in JavaScript.
What is Sinon.js and how can I use it for testing my JavaScript code?
Sinon.js is a library for creating spies, mocks, and stubs in JavaScript. It helps you test your code by allowing you to replace functions with test doubles.
Can you give me an example of how to create a stub with Sinon.js?
Sure! You can create a stub like this: const myStub = sinon.stub(object, 'method');. This replaces 'method' with a stub that you can control.
How do I verify that the stub was called?
You can verify it by using sinon.assert.called(myStub); which checks if the stub was called at least once.
What are some common use cases for Sinon.js?
Common use cases include testing asynchronous code, replacing network requests, and verifying interactions between objects.
