What are test doubles in software testing?
Test doubles are objects that replace real components in tests to isolate behavior and improve test reliability.
Can you explain the different types of test doubles?
Sure! The main types are stubs, mocks, fakes, and spies, each serving different purposes in testing.
How do I decide which type of test double to use?
It depends on your testing goals. Use stubs for simple responses, mocks for verifying interactions, and fakes for more complex scenarios.
Are there any best practices for using test doubles?
Yes, keep them simple, ensure they mimic real behavior closely, and avoid overusing them to maintain test clarity.
