The document is designed as a cookbook that would help you to quickly understand Lmock and design your first tests with the framework. It assumes that you are already familiar with:
JUnit tests (version 3 or 4)
Mocking in general. Ideally we assume that you have already practiced tests implying mocks
In addition to this document, you may be interested by the tutorials delivered with Lmock, under the docs directory. They give a detailed description of the framework, thus require a bit of time to be read.
