An example of an AI chatbot conversation about advanced usage of Sinon.js for testing.
How can I use Sinon.js for advanced testing scenarios?
Sinon.js is a powerful library for creating spies, mocks, and stubs in JavaScript. For advanced usage, you can combine these features to test complex interactions in your code.
Can you give me an example of using a spy with Sinon.js?
Sure! You can create a spy like this: const mySpy = sinon.spy(); mySpy(); console.log(mySpy.called); // true.
What about mocking a function? How would that work?
To mock a function, you can use sinon.mock(). For example: const mock = sinon.mock(myObject); mock.expects('myMethod').once();.
How do I verify that a stub was called with specific arguments?
You can use sinon.assert.calledWith(stub, arg1, arg2); to verify that your stub was called with the expected arguments.
