Junit Test Project for existing Project - Advanced Junit coders only

IMMEDIATE NEED - TO BE COMPLETED BEFORE 26TH APRIL. I'm building a new JUnits(Testing framework of Java) project for an existing module. Any pro in JUnits should be able to do this. So there are existing samples in other modules which can be helpful. So the project should be built like this: 1) A Test Helper java Class 2) Test Data creater class (which is a java class which extras the data from a xml file and creates the test data in the database and it will destroy the same data at the end of the testing) 3) Then a test class which compares one data with another to see if it is working. 4) Finally there will be a fixture class which will call all the test classes one by one. This is the most high level overview. But there are a lot of libraries that are to be added in order to create the basic project and thats where it is stuck right now.
