[Cpptool-develop] Mock object and testing...

[Baptiste L. <gai...@fr...>]

    The Mock*** classes are mock objects created for testing only. They are
used to check for some expectations (http://www.mockobjects.com/). There is
some examples of usage in TransformListTest and ReplaceTextTransformTest.

    The implementation in include/mock/Expectations.h is extremely simple
(convert all calls into a string and check against the expected call list),
but it's enough for what we are doing.
