关于current_path对象，Rspec和capybara，visit和get方法之间的区别

Question

I'm possibly confusing rack and capybara methods here

let!(:admin){FactoryGirl.create(:admin)}

# test passes
describe "visiting #edit page" do
  before { visit edit_user_path(admin) }
  specify { current_path.should eq(edit_user_path(admin)) }
end

# test fails
describe "getting #edit page" do
  before { get edit_user_path(admin) }
  specify { current_path.should eq(edit_user_path(admin)) }
end

The second test fails with:

     Failure/Error: specify { current_path.should eq(edit_user_path(admin)) }

       expected: "/users/51/edit"
            got: "/users/51"

       (compared using ==)

A before(:each) block, sets the current_path to /users/51 , so it looks like it remains that way when using get .

I just want to check here:

• do visit and current_path come from capybara, whereas get comes from rack?
• does the current_path object necessarily require you to use the visit method, in order to keep it updated?

Your issue is a shared issue and was described in a post by Jose Valim .

To be short, in integration tests, only use visit .
