The reason why I chose to do this was because I found myself writing the above many times in (currently unsent) later test cases that I cleaned up. As a result, I felt like it could be wrapped up more nicely with a helper function. That being said, if you think that open coding the idiom looks nicer, I can reroll to inline it.
