Request Header Parser Passes tests when it should not

So my Request Header Parser Microservice project passed all the tests when it was not working correctly. Seems like the testing code could be buggy.

I just finished the other two parameters though and think it should pass.

All but the last commit to this branch was incomplete, yet it still passed.

Any thoughts out there?
