Should this be PollJsAddChoiceTest?

Other than that this looks good.

The old one was class PollJSAddChoice, so PollJSAddChoiceTest.php seems like the right spot for it. RTBC! We could make a follow up to clean up the definition or name if we wanted.

Sorry, I meant the JS acronym capitalization. Shouldn't it be Js in CamelCase?

Does just switching the case work? Lazy patch is lazy :-) .

Looks good! That's what I meant.
