What is the Sinon mocking library and how do I use it?
An example of an AI chatbot conversation about Sinon, a library for creating mocks and stubs in JavaScript testing.
What is the Sinon mocking library and how do I use it?
Sinon is a JavaScript library used for creating mocks, stubs, and spies in your tests. It helps you isolate the code you're testing by replacing dependencies with controlled versions.
Can you give me an example of how to create a stub with Sinon?
Sure! You can create a stub like this: const myStub = sinon.stub(object, 'method').returns('value');. This replaces object.method with a stub that returns 'value'.
What are the differences between mocks, stubs, and spies?
Mocks are used to verify interactions, stubs replace functions and control their behavior, while spies track function calls without altering their behavior.
How do I install Sinon in my project?
You can install Sinon using npm with the command npm install sinon. If you're using a CDN, you can include it directly in your HTML.
