Description

I noticed that a few of the tests had a BaseUnitTest - however, it was entirely unused! So, I removed it and validated that all the tests still passed (they did).

While I was touching these files, I added a variety of other small improvements:

• Import org.junit instead of junt.framework
• Always use expected value as the first argument to assertEqual(expected: Object, actual: Object) - these were frequently backwards in the touched files. (I used a regex to swap these.)
• Removed not-thrown Exception on test function signatures
• For VerificationCodeParserTest.java, use a parameterized JUnit test
