为什么 Rspec 说“失败/错误：无法从回溯中找到匹配行”？

发布于 2024-09-15 08:47:38 字数 1543 浏览 5 评论 0原文

我在这里关注 Rails 教程： http://railstutorial.org/chapters/ fill-in-the-layout#top

当我运行“rspec spec/”时，我收到一堆如下所示的错误：

1) LayoutLinks should have a Home page at '/'
    Failure/Error: Unable to find matching line from backtrace
    stack level too deep
    # C:/Ruby19/lib/ruby/1.9.1/forwardable.rb:185

2) LayoutLinks should have a Contact page at '/contact'
    Failure/Error: Unable to find matching line from backtrace
    stack level too deep
    # C:/Ruby19/lib/ruby/1.9.1/forwardable.rb:185

但是当我在网络浏览器中进入 localhost:3000/ 和 localhost:3000 时/contact，页面在那里并且正确的标题在那里。这是我的 myrailsroot\spec\requests\layout_links_spec.rb 文件：

require 'spec_helper'

describe "LayoutLinks" do

  it "should have a Home page at '/'" do
    get '/'
    response.should have_selector('title', :content => "Home")
  end

  it "should have a Contact page at '/contact'" do
    get '/contact'
    response.should have_selector('title', :content => "Contact")
  end

  it "should have an About page at '/about'" do
    get '/about'
    response.should have_selector('title', :content => "About")
  end

  it "should have a Help page at '/help'" do
    get '/help'
    response.should have_selector('title', :content => "Help")
  end

  it "should have a signup page at '/signup'" do
    get '/signup'
    response.should have_selector('title', :content => "Sign up")
  end

end

任何想法都会很棒，谢谢

I'm following the rails tutorial here: http://railstutorial.org/chapters/filling-in-the-layout#top

When I run "rspec spec/", I get a bunch of errors that look like this:

1) LayoutLinks should have a Home page at '/'
    Failure/Error: Unable to find matching line from backtrace
    stack level too deep
    # C:/Ruby19/lib/ruby/1.9.1/forwardable.rb:185

2) LayoutLinks should have a Contact page at '/contact'
    Failure/Error: Unable to find matching line from backtrace
    stack level too deep
    # C:/Ruby19/lib/ruby/1.9.1/forwardable.rb:185

But when I go in my web browser to localhost:3000/ and localhost:3000/contact, the pages are there and the correct titles are there. Here is my myrailsroot\spec\requests\layout_links_spec.rb file:

require 'spec_helper'

describe "LayoutLinks" do

  it "should have a Home page at '/'" do
    get '/'
    response.should have_selector('title', :content => "Home")
  end

  it "should have a Contact page at '/contact'" do
    get '/contact'
    response.should have_selector('title', :content => "Contact")
  end

  it "should have an About page at '/about'" do
    get '/about'
    response.should have_selector('title', :content => "About")
  end

  it "should have a Help page at '/help'" do
    get '/help'
    response.should have_selector('title', :content => "Help")
  end

  it "should have a signup page at '/signup'" do
    get '/signup'
    response.should have_selector('title', :content => "Sign up")
  end

end

Any ideas would be great, thanks

这是由于 RSpec 2.0.0.beta.19 中的错误造成的。如果您按照教程建议使用 2.0.0.beta.18，它将正常工作。只需将 Gemfile 中的任何版本更改为 beta 18，捆绑安装并再次运行测试即可。

这是我的 Gemfile 中的相关部分。

group :development do
  gem 'rspec-rails', '2.0.0.beta.18'
end

group :test do
  gem 'rspec-rails', '2.0.0.beta.18'
  gem 'spork', '0.8.4'
end

另请注意，Spork 有时也会导致此类问题。如果您遇到莫名其妙的测试失败，特别是如果您刚刚添加了新的控制器或操作，请尝试一下 spork。按 Ctrl-C 并再次运行 spork 服务器。

This is due to a bug in RSpec 2.0.0.beta.19. If you use 2.0.0.beta.18 as the tutorial suggests, it will work fine. Just change whatever version you have in your Gemfile to beta 18, bundle install and run the tests again.

Here's the relevant parts from my Gemfile.

group :development do
  gem 'rspec-rails', '2.0.0.beta.18'
end

group :test do
  gem 'rspec-rails', '2.0.0.beta.18'
  gem 'spork', '0.8.4'
end

Also note that Spork can also cause problems like this from time to time. If you get inexplicable test failures, especially if you just added new controllers or actions, go give spork a kick. Hit Ctrl-C and run the spork server again.

我的 gemfile 看起来像这样，它可以

group :test do 
    gem 'rspec-rails'
    gem 'webrat', '0.7.1'
end

在 rspec-rails (2.1.0) 的地方

工作，但是以下不行：

group :test do 
    gem 'rspec-rails'
    gem 'webrat', '0.7.2'
end

所以我认为这是 webrat 发挥作用。

my gemfile looked like this and it works

group :test do 
    gem 'rspec-rails'
    gem 'webrat', '0.7.1'
end

where rspec-rails (2.1.0)

however following doesn't:

group :test do 
    gem 'rspec-rails'
    gem 'webrat', '0.7.2'
end

So I think it is webrat plays up.

我升级到 beta.20，现已发布。必须将 webrat 添加到我的 gemfile 中并进行另一个捆绑安装。在 gemfile 中，它看起来像这样：

group :test do
  gem "webrat"
  gem 'rspec', '2.0.0.beta.20'
end

干杯

I upgraded to beta.20 which is now out. Had to add webrat into my gemfile and do another bundle install. In the gemfile, it looks like this:

group :test do
  gem "webrat"
  gem 'rspec', '2.0.0.beta.20'
end

Cheers

我只在两次标题测试中看到这个问题。

我的 gemfile 如下...

source 'http://rubygems.org'

gem 'rails', '3.0.0'
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
gem 'gravatar_image_tag', '0.1.0'
gem 'will_paginate', '3.0.pre2'

group :development do
  gem 'rspec-rails', '2.0.0.rc'
  gem 'webrat', '0.7.1'
  gem 'annotate-models', '1.0.4'
  gem 'faker', '0.3.1'
end

group :test do
  gem 'rspec', '2.0.0.rc'
  gem 'webrat', '0.7.1'
  gem 'spork', '0.8.4'
  gem 'factory_girl_rails', '1.0'
end

我也尝试过 rspec-rails 的测试版，但无济于事。

仍然给我错误的两个标题如下：

来自 users_controller_spec.rc

  it "should have the right title" do
    get :index
    response.should have_selector("title", :content => "All users")
  end

  #...

    it "should have the right title" do
      post :create, :user => @attr
      response.should have_selector("title", :content => "Sign up")
    end

错误片段分别为：

Failures:
  1) UsersController GET 'index' for signed-in users should have the right title
     Failure/Error: response.should have_selector("title", :content => "All users")
     expected following output to contain a <title>All users</title> tag:
     <!DOCTYPE html>
     <html>
     <head>
     <meta http-equiv="Content-Type" content="text/html; charset=US-ASCII">
     <title>Ruby on Rails Tutorial Sample App | All Users</title>

和

2) UsersController Post 'create' for non-signed in users failure should have the right title
     Failure/Error: response.should have_selector("title", :content => "Sign up")
     expected following output to contain a <title>Sign up</title> tag:
     <!DOCTYPE html>
     <html>
     <head>
     <meta http-equiv="Content-Type" content="text/html; charset=US-ASCII">
     <title>Ruby on Rails Tutorial Sample App | Sign Up</title>

。

从输出中可以看出，“Sign Up”和“Index”清楚地显示在标题右侧。这是特别令人困惑的，因为以下测试确实有效：

  it "should have the right title" do
    get :new
    response.should have_selector("title", :content => "Sign up")
  end

它适用于同一页面，并且包含与其他“注册”测试相同的标题。 get 方法在此测试中有效，但在“Index”测试中无效。

帮助？

I am only seeing this issue for two of my title tests.

My gemfile is as follows...

source 'http://rubygems.org'

gem 'rails', '3.0.0'
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
gem 'gravatar_image_tag', '0.1.0'
gem 'will_paginate', '3.0.pre2'

group :development do
  gem 'rspec-rails', '2.0.0.rc'
  gem 'webrat', '0.7.1'
  gem 'annotate-models', '1.0.4'
  gem 'faker', '0.3.1'
end

group :test do
  gem 'rspec', '2.0.0.rc'
  gem 'webrat', '0.7.1'
  gem 'spork', '0.8.4'
  gem 'factory_girl_rails', '1.0'
end

I've tried the betas for rspec-rails as well, to no avail.

The two of the titles that are still giving me errors are the following:

From users_controller_spec.rc

  it "should have the right title" do
    get :index
    response.should have_selector("title", :content => "All users")
  end

  #...

    it "should have the right title" do
      post :create, :user => @attr
      response.should have_selector("title", :content => "Sign up")
    end

The snippet from the errors reads:

Failures:
  1) UsersController GET 'index' for signed-in users should have the right title
     Failure/Error: response.should have_selector("title", :content => "All users")
     expected following output to contain a <title>All users</title> tag:
     <!DOCTYPE html>
     <html>
     <head>
     <meta http-equiv="Content-Type" content="text/html; charset=US-ASCII">
     <title>Ruby on Rails Tutorial Sample App | All Users</title>

and

2) UsersController Post 'create' for non-signed in users failure should have the right title
     Failure/Error: response.should have_selector("title", :content => "Sign up")
     expected following output to contain a <title>Sign up</title> tag:
     <!DOCTYPE html>
     <html>
     <head>
     <meta http-equiv="Content-Type" content="text/html; charset=US-ASCII">
     <title>Ruby on Rails Tutorial Sample App | Sign Up</title>

respectively.

As seen by the output, "Sign Up" and "Index" are clearly shown to the right of the title. This is particularly perplexing in that, the following test does work:

  it "should have the right title" do
    get :new
    response.should have_selector("title", :content => "Sign up")
  end

Which is for the same page and contains the same title as the other "Sign Up" test. Also the get method works in this test but not in the "Index" test.

Help?

我可以确认以下 Gemfile 工作正常......

group :test do
  gem 'rspec', '2.0.0.beta.18'
  gem 'spork', '0.8.4'
  gem 'webrat', '0.7.1'

I can confirm that the following Gemfile works correctly...
