在Rails 3.2.3中使用Cucumber和RSpec测试HTTP基本身份验证 [英] Testing http basic authentication with Cucumber and RSpec in Rails 3.2.3
问题描述
我想测试Rails 3.2.3中的内置基本http身份验证机制.我已经尝试在RSpec和Cucumber中测试http身份验证,但是两个工具中的步骤均失败.在黄瓜中,我在运行我的功能时收到以下消息:
I want to test the build-in basic http authentication mechanism in Rails 3.2.3. I have tried to test the http authentication in both RSpec and Cucumber but with a failing step in both tools. In Cucumber I get the following message on running my Feature:
When I perform HTTP authentication as "admin" with "test" # features/step_definitions/web_steps.rb:1
undefined method `env' for nil:NilClass (NoMethodError)
./features/step_definitions/web_steps.rb:3:in `/^I perform HTTP authentication as "([^\"]*)" with "([^\"]*)"$/'
features/sign_in_http.feature:4:in `When I perform HTTP authentication as "admin" with "test"'
这是我的ApplicationController类:
Here is my ApplicationController class:
class ApplicationController < ActionController::Base
protect_from_forgery
http_basic_authenticate_with :name => "admin", :password => "test"
end
黄瓜中的步骤定义:
When /^I perform HTTP authentication as "([^\"]*)" with "([^\"]*)"$/ do |username, password|
@request.env["HTTP_AUTHORIZATION"] = "Basic " + Base64::encode64("username:password")
visit '/'
end
黄瓜功能:
Feature: Signing in via http
Scenario: HTTP sign-in
When I perform HTTP authentication as "admin" with "test"
Then I should see "Welcome to the app."
在RSpec中,http身份验证步骤似乎已通过,但是我从后续步骤中得到消息,因为访问被拒绝",它无法在页面上找到预期的内容:
In RSpec the http authentication step seems to pass but I get the message from the subsequent step, that it couldn't find the expected content on the page because "Access was denied":
1) ApplicationController sign in via http should be successful
Failure/Error: page.should have_content("Welcome to the app.")
expected there to be content "Welcome to the app." in "HTTP Basic: Access denied.\n"
# ./spec/controllers/application_controller_spec.rb:12:in `block (3 levels) in <top (required)>'
这是我的相关规格:
require 'spec_helper'
describe ApplicationController do
describe "sign in via http" do
it "should be successful" do
@request.env["HTTP_AUTHORIZATION"] = "Basic " + Base64::encode64("admin:test")
visit '/'
response.should be_success
page.should have_content("Welcome to the app.")
end
end
end
我也尝试过在黄瓜步骤中的http授权行之前访问根路径,但这给了我关于 @request 的NilClass的相同信息.
使用定义的"admin:test"凭据通过浏览器登录没问题,我可以看到我的应用程序的根页面.
如果有任何建议,我将不胜感激.
I have also tried to visit the root path before the http authorization line in the cucumber step but this gave me the same message about the NilClass for @request.
Login via the browser with the defined "admin:test" credentials is no problem and I can see the root page of my app.
I would be thankful for any suggestions.
推荐答案
这就是我如何使其工作的方式.关键是在访问任何页面之前运行身份验证步骤,否则您已经通过了身份验证.
Here's how I got it to work. The key is to run your authentication step before you visit any pages, else you've already failed the authentication.
在我的专题文章中,我输入:
In my Feature I put:
Background:
Given I perform HTTP authentication as "<id>/<password>"
When I go to the homepage
Then I should see "Text-that-you-should-see-on-your-home-page"
HTTP身份验证的步骤定义如下(我在其他地方找到了此代码,并添加了puts语句以查看发生了什么事情.)
The step definition for the HTTP authentication is as follows (I found this code elsewhere and added the puts statements to see what was going on).
Given /^I perform HTTP authentication as "([^\"]*)\/([^\"]*)"$/ do |username, password|
puts "id/pswd: #{username}/#{password}"
### Following works ONLY if performed first before even going to a page!!!
if page.driver.respond_to?(:basic_auth)
puts 'Responds to basic_auth'
page.driver.basic_auth(username, password)
elsif page.driver.respond_to?(:basic_authorize)
puts 'Responds to basic_authorize'
page.driver.basic_authorize(username, password)
elsif page.driver.respond_to?(:browser) && page.driver.browser.respond_to?(:basic_authorize)
puts 'Responds to browser_basic_authorize'
page.driver.browser.basic_authorize(username, password)
else
raise "I don't know how to log in!"
end
end
