Nicely done Frank! I have left one request that would help users on knowing the naming requirements to prevent a try-and-error repetition situation.

[jyeshe]

It would be helpful for the users to know the exact rule. Something like only digits, letters and the separating symbols '-', '_' or '.'

This is a nice coverage but would you mind moving to a separate test case for the different groups of users? One test, the current one would be left for the viewers, and another one would be created for different expected result contemplating this second group of users.
