Fun fact about JUnit tests: if something throws an exception that prevents your test from completing normally, it can’t clean up after itself. Normally this isn’t a big deal but if, for example, your setup method adds any test data to your database or creates a whole new database, you’re going to need to clean that up manually. Turns out extra databases eat up a lot of hard drive space if you don’t tidy them up for, uh, months. Just fyi :)
