How to solve NameError: undefined local variable or method `user'

I am using Ruby 1.9.3 and Rails 3.2.16.

When I run test suite: bundle exec rspec spec/

I get following error:

1) Authentication authorization in the Users controller visiting the
following page
     Failure/Error: before { visit following_user_path(user) }
     NameError:
       undefined local variable or method `user' for
#<RSpec::Core::ExampleGroup::Nested_7::Nested_3::Nested_3::Nested_2:0x00000006402418>
     # ./spec/requests/authentication_pages_spec.rb:93:in `block (5
levels) in <top (required)>'

  2) Authentication authorization in the Users controller visiting the
followers page
     Failure/Error: before { visit followers_user_path(user) }
     NameError:
       undefined local variable or method `user' for
#<RSpec::Core::ExampleGroup::Nested_7::Nested_3::Nested_3::Nested_3:0x0000000640c2b0>
     # ./spec/requests/authentication_pages_spec.rb:98:in `block (5
levels) in <top (required)>'

I attach authentication_pages_spec.rb file.

Please find it.

How can I solve this error?

Kind regards.

You haven’t assigned anything to the “user” variable used at line 93 inside the method call “following_user_path”

You coudl try to create an user using factory girl, inside your current scope, perhaps using:

let(:user) { FactoryGirl.create(:user) }

Anyway, I strongly recommend that you refactor this spec in order to make it DRY and use context blocks in advance of so many describe blocks.

I use following code

before { visitfollowing_user_path(FactoryGirl.create(:user)) }

in place of

before { visit following_user_path(user) } at line 93.

Now test is pass.

Is right way? can I move further in that chapter to implement
sample_app?

Kind regards.
