Consider a (very) simple calculator class :
|
|
|
|
[simple_calculator]
|
|
|
|
Obviously writing unit tests for such a class is trivial, one of them could be :
|
|
|
|
[simple_zero_plus_zero_is_zero]
|
|
|
|
What now if the calculator class looks more like this :
|
|
|
|
[view]
|
|
[calculator]
|
|
|
|
Writing unit tests becomes a bit more tedious and requires some boiler-plate code, for instance :
|
|
|
|
[my_view]
|
|
[zero_plus_zero_is_zero_without_mock_object]
|
|
|
|
Mock objects main purpose is to alleviate the user from the burden of writing all this boiler-plate code.
|
|
|
|
Here is how the last test can be rewritten using a mock object :
|
|
|
|
[mock_view]
|
|
[zero_plus_zero_is_zero_with_mock_object]
|
|
|
|
and all the checks are automatically handled by the library.
