Why do error messages not display?

At 1:13 in this video Jason Seifer explicitly states that we're adding an another assertion to display an error message. When he runs the test at 1:40 the screen displays "Failed assertion, no message given"

Why did we write that extra assertion that "must be formatted correctly" if it is not displayed? How we correctly display a message for failed assertions?

Hey Scott Lundgren by default the assert statement doesn't return a message. You can specify one by adding a comma and the message you'd like to see.

assert user.errors[:profile_name].include?("Must be formatted correctly."), "Invalid profile name format"
