ruby-on-rails-3 - Capybara 未找到 Rails link_to

_header.html.erb

user_pages_spec.rb

    describe "with valid information" do
        before do
            fill_in "Name",         with: "Example User"
            fill_in "Email",        with: "user@example.com"
            fill_in "Password",     with: "foobar"
            fill_in "Confirmation", with: "foobar"
        end

        it "should create a user" do
            expect { click_button submit }.to change(User, :count).by(1)
        end

        describe "after saving the user" do
            before { click_button submit }
            let(:user) { User.find_by_email('user@example.com') }

            it { should have_selector('title', text: user.name) }
            it { should have_selector('div.alert.alert-success', text: 'Welcome') }
            it { should have_link('Sign out') }
        end

        describe "followed by signout" do
            before { click_link "Sign out" }
            it { should have_link('Sign in') }
        end
    end

失败是:

1) User pages signup with valid information followed by signout
Failure/Error: before ( click_link "Sign out" )
Capybara::ElementNotFound:
no link with title, id, or text 'Sign out' found
(eval):2:in 'click_link'
./spec/requests/user_pages_spec.rb:63:in 'block (5 levels) in (top (required))'

按照手动创建用户过程，它似乎可以工作。该链接位于下拉菜单中，如果这可能与它有关？这是 MHartl rails 教程中他说所有测试都应该通过的地方。

最佳答案

可疑代码显然需要嵌套在前面描述的里面

        describe "after saving the user" do
            before { click_button submit }
            let(:user) { User.find_by_email('user@example.com') }

            it { should have_selector('title', text: user.name) }
            it { should have_selector('div.alert.alert-success', text: 'Welcome') }
            it { should have_link('Sign out') }

            describe "followed by signout" do
                before { click_link "Sign out" }
                it { should have_link('Sign in') }
            end
        end
