An overview of unit testing terminology ( stub vs mock , integration vs. interaction )?

Question

I\'m using more unit tests in my projects and reading all the information I can online and am getting confused by a lot of the terminology. As a result I\'m probably using these

Answer 1

This article from MSN Magazine explains the terms and goes into some detail with examples and some source code.

Basically these are the test doubles:

• Dummy - Dummies contain no implementation
• Stub - stubs are minimal implementations of interfaces or base classes
• Spy - a spy will record which members were invoked
• Fake - more complex, a fake may resemble a production implementation
• Mock - A mock is usually dynamically created by a mock library and depending on its configuration, a mock can behave like a dummy, a stub, or a spy
