I want to delete every new entry made with the tests in order to make it possible to run it again (both on the CI build or manually) without having to manually delete the database entries made with the previous run of the tests. I have found the tearDown() and tearDownAfterClass() but it seems to be useful only for connecting/disconnecting the link with the database. Can I use it to delete the entries made with the tests?

In set-up create an online snapshot of the database and in tear-down reset it to the snapshot point.
Whatever your tests have done to the data in the database or to the structure of it, it is not part of the snapshot which ran before the test and therefore gone.
Please consult your DBA about the options for the database system in use and you might want to bring in a system administrator as well, as it might be possible this is most easily done with a snapshot feature of the file-system and you would be interested to integrate this all with your test-suite.
