使用Webrat测试时如何处理Cookie? [英] How to handle cookies when testing with Webrat?

问题描述

我正在使用Webrat为基于Sinatra的应用程序编写Cucumber测试.对于某些测试，我需要实现

I'm writing Cucumber tests for a Sinatra based application using Webrat. For some tests I need to implement a scenario like

Given I am logged in as admin
When I am visiting "/"
Then I should see "Settings" 

我定义这样的步骤:

Given /^I am logged in as "(.+)"$/ do |user|
    visit "/login"
    fill_in "login", :with => user
    fill_in "password", :with => "123456"
    click_button "Login"
end

When /^I am viewing "(.+)"$/ do |url|
    visit(url)
end

Then /^I should see "(.+)"$/ do |text|
    response_body.should =~ /#{text}/
end

成功创建一个cookie

On success a cookie is created

response.set_cookie(cookie_name, coockie_value)

，然后在用户尝试通过辅助方法访问管理页面时在视图中进行验证:

and then verified in views when user tries to access admin pages via helper method:

def logged_in?
    request.cookies[cookie_name] == cookie_value
end

看起来Webrat没有存储cookie.测试不会报告任何错误，但是会显示"logged_in?".在视图中始终为假，例如未保存cookie.

And it looks like Webrat doesn't store cookies. Tests don't report any error, but "logged_in?" in views is always false, like the cookie was not saved.

我做错什么了吗?如果这只是Webrat的工作方式，那么最佳的解决方法是什么?

Am I doing something wrong? If this is just how Webrat works, what is the best workaround?

推荐答案

真正的问题是Sinatra在测试环境中处理会话的方式.搜索Google网上论坛以进行讨论，但真正的解决方案是简单地使用:

The real problem is the way Sinatra is treating sessions in the test environment. Search the Google group for the discussion, but the real solution is to simply use:

use Rack::Session::Cookie

和不

enable :sessions

使用硒很不错，但是作为解决OP问题的解决方案是过大的.

Using Selenium is nice but it's overkill as a solution for the OP's problem.
