Major Description
When attempting to debug unit tests, it can be very difficult because the no-op logger is used as the default slf4j implementation. We should add a test scoped log4j (or logback, doesn't really matter) dependency so that test output is saved.
Reasons against are that it potentially slows down the tests because of extra IO or that it uses up a non-trivial amount of disk space. If either of these is the case, I feel that they should be addressed separately. Logging can be specifically configured for the cases where we have known issues.
