What is the difference between a mock and a stub in testing?
In testing, a stub is a simple implementation that returns predefined responses, while a mock is a more complex object that verifies interactions.
Can you give me an example of when to use a mock?
Sure! Use a mock when you want to ensure that a specific method was called with the correct parameters during a test.
And when would I use a stub instead?
You'd use a stub when you need to provide a fixed response to a method call without caring about how it was called.
Are there any tools that can help with creating mocks and stubs?
Yes, popular testing frameworks like Mockito for Java and unittest.mock for Python provide built-in support for creating mocks and stubs.
