As mentioned earlier, in the context of software testing, mocking refers to creating simple objects to simulate the behavior of "real" objects. When the unit under test has dependencies on other modules, it is very useful to create mocks of these modules. Doing so allows you to isolate the behavior of the unit under test. It also allows you to simulate multiple conditions that may be difficult to replicate in real life. Mocking makes it easy to test success, failure, and edge case conditions by simulating different inputs or outputs returned by the mock object.
You can mock interfaces and classes by defining your own classes that derive from them, but this can get cumbersome and time consuming. There are multiple free C# ...
