An example of an AI chatbot conversation about the difference between mocks and stubs in software testing.
What is the difference between a mock and a stub in testing?
In testing, a stub is a minimal implementation that simulates the behavior of a component, 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 test how a function interacts with its dependencies, ensuring that the correct methods are called.
And when would I use a stub instead?
You would use a stub when you need to provide predefined responses to calls made during a test, without verifying interactions.
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.
