Using Mock Objects for Testing and Software Design

The goal of this thesis is to provide comprehensive set of information about a technique called the Mock Objects. The importance of bug discovery in a coding phase is now greater, as the complexity of application's development is rising. Test-Driven Development might help us to deal with this issue in the earliest phase. Hence, there is a description of this methodology in the introduction, alongside with an overview of its integral part -- Unit Testing. However, testing is not an easy task in most non-trivial code. The use of Test Doubles, especially Mock Objects, addresses some of these issues and extends the set of testing techniques by a powerful tool. This thesis focuses on its benefits. TDD with Mock objects also promises interesting possibilities in software design. Last chapter presents some of the tools to support Mock Objects manipulation as well as short introduction to their syntax
