Cursus Test Driven Development in Java with Junit

In this course students learn how to apply test driven development in Java. The course discusses the different techniques as well as their position within a software development methodology (including IT Service Management) and development environment. Attention is payed to unit testing and continous integration and how this is done in Java using Junit and Mock Objects. One of the course subjects is also Web Application Testing using HttpUnit. In appendices attention is payed to issues regarding Writing High-Performance Applications, like profiling and benchmarking and code and design optimization techniques.
