What are the best practices for using mocks and stubs in testing?
Best practices include using mocks for behavior verification and stubs for state verification. Keep them simple and focused.
Can you explain the difference between mocks and stubs?
Sure! Mocks are used to verify interactions, while stubs provide predefined responses to calls made during tests.
When should I use mocks instead of stubs?
Use mocks when you need to verify that certain methods were called with specific parameters. Use stubs when you just need to provide fixed responses.
Are there any tools you recommend for creating mocks and stubs?
Yes! Popular tools include Mockito for Java, Sinon.js for JavaScript, and unittest.mock for Python.
