An example of an AI chatbot conversation about using 'sinon' for testing in JavaScript.
Can you give me some examples of how to use 'sinon' in JavaScript?
Sure! 'Sinon' is a library for creating spies, mocks, and stubs in JavaScript. For example, you can create a spy like this: const mySpy = sinon.spy();.
How do I use a stub with 'sinon'?
You can create a stub to replace a function with a fake implementation. For example: const myStub = sinon.stub(obj, 'method').returns(42);.
What is the difference between a spy and a stub?
A spy records the calls made to a function, while a stub replaces the function with a fake implementation that you can control.
Can you show me an example of using 'sinon' with promises?
Absolutely! You can stub a function that returns a promise like this: sinon.stub(obj, 'asyncMethod').returns(Promise.resolve('success'));.
