An example of an AI chatbot conversation about using Sinon.js for JavaScript testing.
How do I use Sinon.js for testing my JavaScript code?
Sinon.js is a library for creating spies, mocks, and stubs in JavaScript. You can use it to test your code by replacing functions with test doubles.
Can you give me an example of how to create a spy?
Sure! You can create a spy like this: const mySpy = sinon.spy(); Then you can call it and check if it was called using mySpy.called.
What about stubs? How do they differ from spies?
Stubs are similar to spies, but they can also replace the implementation of a function. For example: const myStub = sinon.stub(); myStub.returns(42); This will make the stub return 42 when called.
Can I use Sinon.js with other testing frameworks?
Yes, Sinon.js works well with popular testing frameworks like Mocha, Jasmine, and Jest. You can integrate it easily into your test setup.
