Rspec helper test needs access to a controller method

I have an Rspec test for a helper method which requires access to my current_user method provided by Devise. The issue is when I use the login_user macro in my tests for helpers they don't work!

Here is what my test looks like:

describe 'follow_link' do
  before :each do
    login_user
  end

  it "display 'follow' if the curren_user is not following" do
    user = Factory :user
    helper.follow_link(user).should == 'Follow'
  end
end

But it fails with this:

Failure/Error: login_user
 NoMethodError:
   undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_2:0x007faf8c680090>
# ./spec/support/macros.rb:4:in `login_user'
# ./spec/helpers/users_helper_spec.rb:29:in `block (3 levels) in <top (required)>'

And that macro looks like this:

def login_user
  @user = Factory(:user)
  visit new_user_session_path

  # fill in sign in form
  within("#main_container") do
    fill_in "user[email]", with: @user.email
    fill_in "user[password]", with: @user.password
    click_button "Sign in"
  end
end

I've required:

require 'spec_helper'

in my test and everything but that method still isn't available.

Google brought me here, but the answers above didn't help me, after a bit more research I found the blog below.

My Error:

NoMethodError:
       undefined method `visit' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1:0xa49a73c>

Since Capybara 2.0 one has to use folder spec/features capybara commands don't work in folder spec/requests anymore.

Blog that helped me: http://alindeman.github.com/2012/11/11/rspec-rails-and-capybara-2.0-what-you-need-to-know.html

Hope you find this usefull.

Friend 'visit' is the method of Capybara which is used for writing integration test cases.

For writing RSpec unit test cases you need to stub the current_user method call and focus on the functionality of the helper method.

describe 'follow_link' do
  before :each do
   @user = Factory :user
   helper.stub(:current_user).and_return(@user)
  end

  it "display 'follow' if the curren_user is not following" do
    helper.follow_link(@user).should == 'Follow'
  end
end

Generally, in such cases, I mocking controller methods: mock(current_user){nil}
