An example of an AI chatbot conversation about test doubles vs real objects in software testing.
What are the differences between test doubles and real objects in testing?
Test doubles are objects that simulate the behavior of real objects in controlled ways, while real objects are actual implementations used in production.
Can you give me examples of different types of test doubles?
Sure! The main types of test doubles are stubs, mocks, fakes, and spies. Each serves a different purpose in testing.
When should I use mocks instead of stubs?
Use mocks when you need to verify interactions between objects, while stubs are used to provide predefined responses.
Are there any downsides to using test doubles?
Yes, over-reliance on test doubles can lead to tests that don't accurately reflect real-world behavior, potentially hiding bugs.
