This seems effecient. I'll make amends to my code soon. I'm pretty new here so I wasn't aware that this could be done.

but why did you categorize it as an "issue?" My honor gets deducted by one everytime you do so.And could you elaborate a little more on what you mean by "they are all in a single test case, perhaps could split them into separate test cases." thank you :)

"The initial code block is not formatted properly - brackets are misaligned." this also seems like a big non issue.

I really have no idea what you're talking about. and there are test cases for undefined. could you elaborate a little more?
