Now Repository module has very few JUnit tests. There are only two, KeyValidatorRepositoryTest and TryGetTest. There are
some tests, but they don't follow JUnit and Netbeans standards, so they are not run on incremental builds. The following
should be done:
1) existent tests should be coneverted to JUnit so that they will be run on incremental build
2) other tests should be added to cover all relevant repository functionality
several tests were added. Vladimir is working on adding more ATM.
