Rake Test Error - test_should_get new is already defined in UserControllerTest

Question

I am currently on Chapter 6 on RoR tutorials (Hartl's) figuring out modeling users. And, I ran into a problem when I run the rake test - I constantly get an error message shown below:

/u$ bundle exec rake test
rake aborted!
test_should_get_new is already defined in UsersControllerTest
/Users/joebcvan/.rvm/gems/ruby-2.2.0@global/gems/activesupport-      
4.2.0/lib/active_support/testing/declarative.rb:14:in `test'
.
.
.

/Users/joebcvan/.rvm/gems/ruby-2.2.0@global/gems/railties-    
4.2.0/lib/rails/test_unit/sub_test_task.rb:20:in `invoke_rake_task'
/Users/joebcvan/.rvm/gems/ruby-2.2.0@global/gems/railties-
4.2.0/lib/rails/test_unit/testing.rake:8:in `block in <top (required)>'
Tasks: TOP => test:run
(See full trace by running task with --trace)

So, I have taken a look at the user_Controller_test.rb file, and tried fidgeting here, but no luck. My user_controller_test.rb is shown below.

require 'test_helper'

class UsersControllerTest < ActionController::TestCase

  test "should get new" do
    get :new
    assert_response :success
  end

end

I have tried deleting the four lines of code shown below

test "should get new" do
    get :new
    assert_response :success
  end

and ran the rake test, and the error message now appears as below:

  1) Error:
SiteLayoutTest#test_should_get_home:
SyntaxError: /Users/joebcvan/workspace/sample_app/app/models/user.rb:5: syntax         
error, unexpected ':', expecting keyword_end
        format: { with: VALID_EMAIL_REGEX}
           ^


Error:
SiteLayoutTest#test_should_get_home:
NoMethodError: undefined method `each' for nil:NilClass



  2) Error:
SiteLayoutTest#test_should_get_help:
SyntaxError: /Users/joebcvan/workspace/sample_app/app/models/user.rb:5: syntax 
error, unexpected ':', expecting keyword_end
        format: { with: VALID_EMAIL_REGEX}
           ^

 12) Error:
UserTest#test_name_should_not_be_too_long:
SyntaxError: /Users/joebcvan/workspace/sample_app/app/models/user.rb:5: syntax     
error, unexpected ':', expecting keyword_end
        format: { with: VALID_EMAIL_REGEX}
           ^



 13) Error:
UserTest#test_should_be_valid:
SyntaxError: /Users/joebcvan/workspace/sample_app/app/models/user.rb:5: syntax 
error, unexpected ':', expecting keyword_end
        format: { with: VALID_EMAIL_REGEX}
           ^


13 runs, 0 assertions, 0 failures, 13 errors, 0 skips

And now I am stuck.. I am a beginner in RoR, and I feel helpless... I don't know how to figure out these error codes.

I will highly appreciate your expert advice please.

Thank you.

Sounds like either something is loading this file twice or you have defined UsersControllerTest in another file — Frederick Cheung, Feb 03 '15 at 12:18

The errors are telling you a number of things, but it might all be related to the first error.

SyntaxError:

A syntax error is invalid code. The Ruby parser can't understand it, and the exception is kind enough to show you the offending line (as well as tell you the line number):

format: { with: VALID_EMAIL_REGEX}
      ^

The colon wasn't expected there. What I can't tell you is if you are missing an open bracket or not ({) on a preceding line. You'll have to double check your code around there.

Anything with nil

The line:

NoMethodError: undefined method `each' for nil:NilClass

Suggests that you are trying to call the each method on a variable that wasn't set. In this case it looks like you were trying to iterate through a collection. nil is the default value for any variable until you set it with something else.

All your exceptions are variations of these two.

Tip: I would like to add some incident that might help others. While fixing after an error from test, be aware your next changed may not responded and keep display the same errors: Then you may need to kill existing process for that errors. Try

$ps -a

Looking for your app eg: sample_app

$23507 ttys004    0:00.36 spring server | sample_app | started 2 mins ago

Then kill

$kill -9 23507

And now run 'rails test' and continue to fix it.
