ruby-on-rails - 使用黄瓜检查页面标题

Question

特征

Scenario: As a user that has not signed in I want to be able to sign up for provisioner
        Given I am not logged in
        When I go to the home page
        And click on the "Sign Up" button
        Then I should be on the page with the title: "Sign Up"
        When I provide valid information
        And click the "Submit" button
        Then I should see "Account is being created and verified, you will receive an   email with instructions once account has been approved"
        And the application should send the administrator an email
        And I should be redirected to the home page as an anonymous user

脚步

When /^I go to the home page$/ do
  visit root_path
end

When /^click on the "([^"]*)" button$/ do |page_name|
  click_link page_name
end

Then /^I should be on the page with the title: "([^"]*)"$/ do |page_title|
  response.should have_selector('title', :content => "#{page_title}")
end

错误

expected css "title" to return something (RSpec::Expectations::ExpectationNotMetError)

它在Then步骤失败，但是当我手动转到该页面时，该页面确实呈现标题：“注册”。我希望它确保它在测试中进入正确的位置。我如何检查它？

感谢您提前提供的所有帮助。

Answer 1

试试这个：

page.should have_css('head title', :text => title)

Answer 2

从 2.1 开始，您可以这样做：

expect(page).to have_title "my_title"

Answer 3

这可能会发生，因为默认情况下水豚选择器设置为CSS尝试将其更改为

response.should have_xpath('//title', :text => "#{page_title}")

Answer 4

如果您使用的是 cucumber-rails gem，请尝试使用

assert page.has_title?(page_title), "page has title of '#{page.title}'"
