I got this error in rspec while I do not have any variable or method with that name, I even searched all over the project. This happens when I run Rspec for all the test cases, while individual test cases work fine.



I was upgrading the ruby on rails version from ruby 2.3.3 rails 4.1.6. and I upgraded the version one by one, and I have all test passed after reaching rails 5.1.6 with ruby 2.4.5 I got this error. while all the tests also worked normally with the same ruby version and rails 5.0.7



Please let me know if you have any idea how to solve this.



I rebuild the spec_helper.rb again using bin/rspec --init and I added the dependencies and I have a longer trace now

    @MohamedSami The error points to: app/mailers/devise/mailer.rb:12. What's in that file? What's on line 12? And the problem was originally triggered from spec/controllers/answers_controller_spec.rb:150. What is this test? What's on line 150?

    ...So the question comes back, for the third time, to: Can you please provide a Minimal, Complete, and Verifiable example? It looks like you're doing something "wrong" in the tests, like trying to use rack-test without defining an app. But I don't know what's wrong, because you haven't shared any code.

I got this error in rspec while I do not have any variable or method with that name, I even searched all over the project. This happens when I run Rspec for all the test cases, while individual test cases work fine.



I was upgrading the ruby on rails version from ruby 2.3.3 rails 4.1.6. and I upgraded the version one by one, and I have all test passed after reaching rails 5.1.6 with ruby 2.4.5 I got this error. while all the tests also worked normally with the same ruby version and rails 5.0.7



Please let me know if you have any idea how to solve this.



I rebuild the spec_helper.rb again using bin/rspec --init and I added the dependencies and I have a longer trace now

  • @arieljuod do you know what could be the cause for this?

    @MohamedSami The error points to: app/mailers/devise/mailer.rb:12. What's in that file? What's on line 12? And the problem was originally triggered from spec/controllers/answers_controller_spec.rb:150. What is this test? What's on line 150?

    ...So the question comes back, for the third time, to: Can you please provide a Minimal, Complete, and Verifiable example? It looks like you're doing something "wrong" in the tests, like trying to use rack-test without defining an app. But I don't know what's wrong, because you haven't shared any code.

I got this error in rspec while I do not have any variable or method with that name, I even searched all over the project. This happens when I run Rspec for all the test cases, while individual test cases work fine.



I was upgrading the ruby on rails version from ruby 2.3.3 rails 4.1.6. and I upgraded the version one by one, and I have all test passed after reaching rails 5.1.6 with ruby 2.4.5 I got this error. while all the tests also worked normally with the same ruby version and rails 5.0.7



Please let me know if you have any idea how to solve this.



I rebuild the spec_helper.rb again using bin/rspec --init and I added the dependencies and I have a longer trace now

    @MohamedSami The error points to: app/mailers/devise/mailer.rb:12. What's in that file? What's on line 12? And the problem was originally triggered from spec/controllers/answers_controller_spec.rb:150. What is this test? What's on line 150?

    ...So the question comes back, for the third time, to: Can you please provide a Minimal, Complete, and Verifiable example? It looks like you're doing something "wrong" in the tests, like trying to use rack-test without defining an app. But I don't know what's wrong, because you haven't shared any code.

It seems that the issue was one of the controllers' files, I was including a depreciated Rack::Test::Methods which made the conflict. If you experience a similar issue, remove it in rails 5.1
