Ruby on rails 4 rails应用程序中的cucumber测试似乎并没有提交表单让用户登录

我正在尝试使用cucumber和webrat测试我的rails应用程序。我正试图让测试以已创建并存储在数据库中的用户身份登录，但出现以下错误：

然后我看到一条登录错误消息#features/step_definitions/user_steps.rb:16 预期以下元素的内容包含“欢迎管理员”：

我更改了代码，让它登录一个用户，而不是因为无效的详细信息而无法登录一个用户，因为这不起作用，我不确定这是否是因为它没有接收到flash消息

这是步骤定义文件（user_steps.rb）

以下是login.feature文件：

Feature: Login
    In order to access my account 
    As a user
    I want to be able to login 

        Scenario: User does not have an account
            Given I do not have an account
            When I attempt to login with my details 
            Then I see a login error message
            And I should not be logged in

        Scenario: User enters incorrect Login
            Given I have an account
            And I am not logged in
            When I enter an incorrect Login
            Then I see a login error message
            And I should not be logged in

        Scenario: User enters incorrect password
            Given I have an account
            And I am not logged in
            When I enter an incorrect password
            Then I see a login error message
            And I should not be logged in

        Scenario: User logs in successfully
            Given I have an account
            And I am not logged in
            When I enter my correct login
            And I enter my correct password
            Then I see a successful login message
            When I return to the application 
            Then I should still be logged in

这是env.rb文件

require 'cucumber/rails'
require 'webrat'
require 'cucumber/rails/world'
require 'webrat/core/matchers'

Webrat.configure do |config|
config.mode = :rack
config.open_error_files = false
end

World(Webrat::Methods)
World(Webrat::Matchers)

ActionController::Base.allow_rescue = false


begin
  DatabaseCleaner.strategy = :transaction
  rescue NameError
  raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish              to use it."
  end

 Cucumber::Rails::World.use_transactional_fixtures = false

class ActiveSupport::TestCase
setup do |session|
session.host! "localhost:3001"
end
end

rails/blob/master/features/choose_javascript_database_strategy.feature
Cucumber::Rails::Database.javascript_strategy = :truncation

以下是文件：

# Use jquery as the JavaScript library
gem "jquery-rails", "~> 2.3.0"
gem 'jquery-ui-rails', '4.1.2'

# Turbolinks makes following links in your web application faster. Read more:    https://github.com/rails/turbolinks

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
  end

group :development, :test do
  gem 'rspec-rails', '~> 3.0.0'
  gem 'cucumber-rails', require: false
  gem "webrat"
  gem 'factory_girl_rails'
  gem 'selenium-client'
  gem 'capybara'
  gem 'database_cleaner'
end

好的，那么你的步骤是：

Then /^I see a login error message$/ do 
   visit home_path
   response.should contain("Welcome admin")
end

您得到的错误是：

RSpec:：expections:：ExpectationNotMetError

我认为这只是一个例子，你的期望是错误的，但至少有点误导。我们实际上应该看到一个错误（比如“无法登录”），但我们正在寻找更像欢迎信息的

“欢迎管理员”

我们可以通过将

放置response.body

在期望看到呈现的内容之前来调试它

也可能是黄瓜没有等待请求完成。我们可以尝试添加

find（“#some element”）

，如果找不到元素，它将等待几秒钟，然后失败

编辑：另外，我刚刚注意到您正在运行的功能不是您包含的功能（

login.feature

），因此您试图在不尝试错误登录的情况下查看错误消息。

谢谢，它现在已排序。
