Smoketests

I've been finding a lot of bugs but I want to finish these smoketests. I just had a problem where the app was saying I could not login with credentials but it turns out I had logged in the entire time without any notice.

• One smoketest was to add a category to a question which passed
• Another one was to see if a user would be restricted from signing up if their email address was invalid which worked except that the email address was not red when it should have been. I wrote "The user is prevented from signing up but the email address is not highlighted red if something invalid is put after the "@" symbol, like "hello@mail.com", but emails like "hello@" and "hello" are red and emails with a period and then a blank space are highlighted as red such as "hello@mail."."
• I had to try and change my username which failed because my username was changed but no feedback was provided.
