I'll go with "run this test?"

I'd rather keep the "[yY]|[yY]es" options it doesn't really make sense
not to.
I can see the argument for having all other input default to no. You
really see a mix of the two in the wild where sometimes junk will
default to no and sometimes it will loop and ask again.
I tend to think that most of the time when it doesn't match one of the
options it's going to be because of a mis-type by the user and they'd
probably prefer that it looped than have to run the command again.

I don't really see this as being necessary, I guess there could be some
ambiguity as to what has happened but I think it's pretty obvious that
the test has aborted.
I'll change it so that the skip message is printed.

Yeah if I have return 0 here (because bash things) then it'll print the
skip message and abort the test.

Ok, I've seen places where the options are specified like this but will
change it to just have the same question again.
