test error:-in Ruby on rails - ruby-on-rails

Question

I'm working with ruby on rails and I'm having a problem while running a "ruby -Itest test/models/user_test.rb". I get an error when I make changes in the regular expression /^[a-zA-Z0-9-]+$/ and now I am stuck in this problem and I don't know how to get over it.
My user.rb file:-
validates :profilename, presence: true,
uniqueness: true, format: { with: /^[a-zA-Z0-9-]+$/ , multiline: true,
message: 'Must be formatted correctly.' }
Running test:-
$ ruby -Itest test/models/user_test.rb

Here is the code for a_user_can_have_a_correctly_formatted_profile_name
test "a user can have a correctly formatted profile name" do
user = User.new(first_name: 'sarah', last_name: 'gupta', email: 'sarah089#gmail.com')
user.password = user.password_confirmation = 'welcome'
user.profile_name = 's_arah-1'
assert.user.valid?
end
Thanks for your help!

It looks like the answer to your question is in the file user_test.rb. Try checking where test_a_user_can_have_a_correctly_formatted_profile_name is defined, and where it's called: according to the error, it's being called without the required one or two arguments. I'm guessing you need to give it a test username.
