如何在Rails / Capybara / Cucumber或Rspec中测试帖子

I'm using rspec, cucumber and capybara and I'm looking for a way to test that a malicious user can't hack a form then post to an url he/she doesn't have permission to. I have my permissions set up in cancan such that this "should" work, however, the only way I can test it is by hacking a form myself.

我正在使用rspec，黄瓜和水豚，我正在寻找一种方法来测试恶意用户无法破解表单然后发布到他/她没有权限的网址。我已经在cancan中设置了我的权限，这样“应该”可以工作，但是，我可以测试它的唯一方法是自己黑客攻击表单。

How can I automate this sort of testing? With webrat I could do this in a unit test with rspec with something like

如何自动进行此类测试？有了webrat，我可以用rspec进行单元测试

put :update, :user_id => @user.id, :id => @user_achievement.id
response.should contain("Error, you don't have permission to access that!")

In capybara, however, visit only does get's it seems. I can't find a way to do this, I've googled everwhere.

然而，在水豚中，访问只是看起来似乎。我找不到办法做到这一点，我已经google了无处不在。

Any help would be much appreciated, Thanks

任何帮助将不胜感激，谢谢

I think you can do this with rack-test https://github.com/brynary/rack-test

我认为你可以用机架测试https://github.com/brynary/rack-test来做到这一点

in your Gemfile:

在你的Gemfile中：

gem 'rack-test'

in your env.rb file

在你的env.rb文件中

module CapybaraApp
  def app; Capybara.app; end
end
World(CapybaraApp)
World(Rack::Test::Methods)

step defintions somewhere:

步骤定义：

When /^I send a POST request to "([^"]*)"$/ do |path|
  post path
end

Most of what I learned came from here: http://www.anthonyeden.com/2010/11/testing-rest-apis-with-cucumber-and-rack-test

我学到的大部分内容来自这里：http：//www.anthonyeden.com/2010/11/testing-rest-apis-with-cucumber-and-rack-test

UPDATE: I think you can skip the changes to your env.rb file with newer versions of Rails and/or Cucumber (not sure which, I just don't do that part on my newer projects and it works fine)

更新：我认为你可以跳过你的env.rb文件的更改与更新版本的Rails和/或黄瓜（不知道哪些，我只是不做我的新项目的那部分，它工作正常）

Same as @Josh Crews I've largely based this off of: http://www.anthonyeden.com/2010/11/testing-rest-apis-with-cucumber-and-rack-test/#comment-159. But there are two notable exceptions: 1) I test the actual response body, 2) I demonstrate how to test a POST request. Here's an example using Rails 3.0.9:

和@Josh Crews一样，我主要基于这个：http：//www.anthonyeden.com/2010/11/testing-rest-apis-with-cucumber-and-rack-test/#comment-159。但有两个值得注意的例外：1）我测试实际的响应体，2）我演示了如何测试POST请求。这是使用Rails 3.0.9的示例：

Steps:

脚步：

# features/step_definitions/api_step.feature
When /^I send a GET request to "([^\"]*)"$/ do |url|
  authorize(User.last.email, "cucumber")

  header 'Accept', 'application/json'
  header 'Content-Type', 'application/json'

  get url
end

When /^I send a POST request to "([^\"]*)" with:$/ do |url, body|
  authorize(User.last.email, "cucumber")

  header 'Accept', 'application/json'
  header 'Content-Type', 'application/json'

  post url, body
end

Then /^the JSON response should have (\d+) "([^\"]*)" elements$/ do |number_of_children, name|
  page = JSON.parse(last_response.body)
  page.map { |d| d[name] }.length.should == number_of_children.to_i
end

Then /^I should receive the following JSON response:$/ do |expected_json|
  expected_json = JSON.parse(expected_json)
  response_json = JSON.parse(last_response.body)

  response_json.should == expected_json
end

Then /^I should receive the following JSON object response:$/ do |expected_json|
  expected_json = JSON.parse(expected_json)
  response_json = JSON.parse(last_response.body)

  if expected_json['id'] == 'RESPONSE_ID'
    expected_json['id'] = response_json['id']
  end

  response_json.should == expected_json
end

Feature:

特征：

# features/api/some_feature.feature
Feature: Users API
  Background:
    Given the following users exist:
      | id | name |
      | 1  | Joe  |
      | 2  | Sue  |
      | 3  | Paul |

  Scenario: Index action
    When I send a GET request to "/users/"
    Then the JSON response should have 3 "user" elements
    And I should receive the following JSON response:
      """
      [
        {
          "id":1,
          "name":"Joe"
        },
        {
          "id":2,
          "name":"Sue"
        },
        {
          "id":3,
          "name":"Paul"
        }
      ]
      """

  Scenario: Create action
    When I send a POST request to "/users/" with:
      """
      {
        "name":"Polly"
      }
      """
    Then I should receive the following JSON object response:
      """
      {
        "id":"RESPONSE_ID",
        "name":"Polly"
      }
      """
    And I send a GET request to "/users/"
    And the JSON response should have 4 "user" elements
