The JUnit testing framework allows you to write and run test cases and test suites for Java applications. JUnit tests can be organized into a hierarchy of test suites, which can be run and re-run automatically after changing the code. This is useful for automatic non-regression testing, and ensures complete synergy between coding and testing.

The Objecteering/UML based on the MDA (Model Driven Architecture) concept, generates code from the UML model of your application. Objecteering/UML Modeler helps to create consistent UML application models and Objecteering/Java Developer generates complete Java and EJB code from your model, and dynamically maintains consistency between the model and the generated code.

To successfully provide a seamless integration from UML models to Java code and Java tests, Objecteering/UML has introduced:

• the means of designing tests using UML notation itself, through the use of UML sequence diagrams
• the opportunity of running tests based on both test code generated from the UML test model and facilities provided by the Junit framework.
