You'll notice that most newer tests in the tools use `##` for proper comments. Comments should also be full sentences as a general rule, with trailing full stops. Applies to all the comments in the file.

Also, sorry, but this was a little more detailed than I'd imagined. The test is pretty self-documenting as to what yaml2obj does and what the initial object layout looks like (the YAML is simple and fairly clear), so I think you could just get rid of everything after the first line, just keeping the individual comments for the test cases to highlight what is significant about each line.
