Question

我正在研究MH的教程，我不断收到这三个错误。它说'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。任何建议

Answer 1

我在规范中快速修改了你的格式，现在看看，为什么......

应该更明显

您在let(:submit) { "Create my account" }上下文中定义了signup，但您正试图在after saving the user上下文中使用它。您需要将其移出，以便两者都可以看到它，或者在其他上下文中重新定义它。

说实话，你的那部分规格没有意义，你提交的是什么？

Answer 2

要在保存用户块后测试，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，因此您必须嵌套您的上下文{{ 1}}位于after saving user上下文中的describe "with valid information" do内，您已经 let（：submit）声明创建了您的提交变量。

您的代码如下所示：

"sign up"

结论：只需在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阻止after saving the user之前移动end阻止
