What are the best practices for mocking in Node.js?
An example of an AI chatbot conversation about best practices for mocking in Node.js.
What are the best practices for mocking in Node.js?
Some best practices include using libraries like Sinon.js, keeping mocks simple, and ensuring they are isolated.
Can you explain how to use Sinon.js for mocking?
Sure! Sinon.js allows you to create spies, stubs, and mocks. You can use sinon.stub() to replace a function with a mock.
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 and can control its behavior.
How do I ensure my tests remain isolated?
You can achieve isolation by resetting mocks after each test and avoiding shared state between tests.
