Capybara / Cucumber没有找到flash消息

Question

我无法让Cucumber / Capybara在用户登录后在页面上找到“成功”的Flash消息。如果我在浏览器中手动执行此操作，我就能看到该消息，所以我'我以为我在步骤中做错了什么。

user_login.feature

Feature: User login 

  Scenario: A user successfully logs in from the homepage
    Given A user is on the homepage
    When the user clicks "Login"                                                     
    And they fill out the form
    Then they should see a success message

step_definition

Given /^A user is on the homepage$/ do
  @user = Factory.create(:user)
  visit root_path
end

When /^the user clicks "(.*?)"$/ do |arg1|
  click_link arg1
end 

When /^they fill out the form$/ do
  fill_in "email", with: @user.email
  fill_in "password", with: "blahblah1"
  click_button "Sign in"                                                             
end

Then /^they should see a success message$/ do
  page.should have_selector ".alert", text: "Logged in!"
end

输出

expected css ".alert" with text "Logged in!" to return something (RSpec::Expectations::ExpectationNotMetError)

Answer 1

基本上，我做了一个 DERP 。我使用（密码）填写表单的凭据与我通过FactoryGirl创建的用户不同。这导致在我测试“成功”消息时出现“无效的电子邮件/密码”消息。

要调试页面输出的内容，我在规范中添加了page.should have_content "asdfsdfas"。当测试失败时，Cucumber输出它在页面上获得的内容与您预期接收的内容相比。
