Update the test to use JUnit 5

[plamentotev]

Now that Java 8 is required we can use JUnit 5. It brings some nice features such as Assume that allows a test to be skipped based on run-time conditions. There are some tests that are not run on Windows but currently they are reported as passed, with Assume they will be properly reported as skipped.

This should now be changed to JUnit 5 😉

I've updated the description. @jorsol do you work on that or you just noticed the ticket. I ask because I've just started playing around with migrating to JUnit5.

I just noticed the ticket, I wish to work on this but I don't have enough time to tackle this.

I've migrated the test and they work with JUnit 5. I think I'll do some obvious improvements that are supported in JUnit 5 and then merge it master. Any suggestion/comments are greatly appreciated.
