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))'

在手动创建用户过程之后，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？这是在 MHartl rails 教程中他说所有测试都应该通过的地方。

可疑代码显然需要嵌套在前面描述的内部

        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

最后一个描述中的before块还没有创建用户。这就是用户（尚不存在）当前未登录的原因，因此没有“退出”链接。

一种可能的解决方案是click_button 'submit'在 before 块中。另一个是完全跳过块中的注销before，因为此时没有用户登录。

是的，它应该嵌套在前面的描述中。我可以确认这也适用于本教程的 Rails 4 版本。
