How do I use Sinon.js with Mocha for testing?
An example of an AI chatbot conversation about using Sinon.js with Mocha for testing JavaScript applications.
How do I use Sinon.js with Mocha for testing?
You can use Sinon.js with Mocha to create spies, mocks, and stubs for your tests. First, install Sinon.js using npm.
What are spies, mocks, and stubs?
Spies are functions that record how they are called, mocks are fake functions with pre-programmed behavior, and stubs are functions that replace real ones.
Can you give me an example of a stub in a Mocha test?
Sure! Here's a simple example: const myStub = sinon.stub(myObject, 'myMethod').returns('fake value'); This replaces myMethod with a stub that returns 'fake value'.
How do I assert that a stub was called?
You can use sinon.assert.called(myStub); to check if the stub was called during the test.
