我正在研究 MH 的教程，但我不断收到这三个错误。这是说“提交”是一个未定义的变量，我不明白为什么。不确定是什么问题。有什么建议么

我在规范中快速修复了您的格式，现在看一下，应该更清楚为什么......

您已let(:submit) { "Create my account" }在上下文中定义signup，但您试图在after saving the user上下文中使用它。您需要将其移出以便双方都能看到它，或在其他上下文中重新定义它。

老实说，您的规范的那部分没有意义，您要提交什么？

要在保存用户块后进行测试，您应该在创建用户成功时执行此操作，这意味着在 with valid information上下文中，因此您必须将上下文嵌套after saving user在describe "with valid information" do上下文"sign up"中，并且您已经创建了创建提交变量的let(:submit)声明。

您的代码将如下所示：

describe "sign up" do 

  before { visit signup_path } 

  let(:submit) { "Create my account" } 
  .
  .
  .
  .

  describe "with valid information" do

    # here you fill fields for signing up a new user
    .
    .
    .
    describe "after saving the user" do
      # when you are here, you have already filling fields of signup form, so you should submit these fields and the code below let you do this
      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
  end
end

结论：只需在of块after saving the user之前移动块endsign up
