I think there is an error in the relevant code section.

The first letter Z looks capitalized as in: /[a-ZA-Z0-9_-+/

Shouldn't the format be: /[a-zA-Z0-9_-+/

Note that I am using rails 4 and thus I also found that I needed to format my expression using: /\A[a-zA-Z0-9_-]+\z/

Where "\A" and "\z" test the start and end of the string.

Without this modification I would fail the test "a user should have a profile name without spaces" on the line: assert !user.errors[:profile_name].empty?

Thank you Jorge. Yes, this was driving me crazy for like an hour. The suggested code makes the test fail. Treehouse needs to fix this.

Your code is correct for the regular expression and makes the test pass!

Thank you!
