使用Cookie与Rack :: Test [英] Using Cookies with Rack::Test

问题描述

我想使用Rack :: Test为我的Sinatra应用程序编写RSpec测试。我不明白如何使用cookies。例如，如果我的应用程序设置cookie（不通过：会话）如何检查该cookie是否正确设置？

I'm trying to write RSpec tests for my Sinatra application using Rack::Test. I can't understand how I can use cookies. For example if my application set cookies (not via :session) how can I check whether that cookie is properly set?

此外，如何使用该Cookie发送请求？

Also, how can I send requests with that cookie?

推荐答案

Rack :: Test保持一个持久化请求的cookie jar。您可以使用 rack_mock_session.cookies 访问它。假设您有这样的处理程序：

Rack::Test keeps a cookie jar that persists over requests. You can access it with rack_mock_session.cookies. Let's say you have a handler like this:

get '/cookie/set' do
    response.set_cookie "foo", :value => "bar"
end

现在你可以用这样的测试：

Now you could test it with something like this:

it 'defines a cookie' do
    get '/'
    rack_mock_session.cookie_jar["foo"].should == "bar"
end

您也可以使用 last_request.cookies ，但是如名字所示，它包含最后一个请求的cookie，而不是响应。您可以使用 set_cookie 设置Cookie，然后使用 clear_cookies 清除Cookie。

You can also access cookies with last_request.cookies, but as the name says, it contains the cookies for the last request, not the response. You can set cookies with set_cookie and clear them with clear_cookies.

it 'shows how to set a cookie' do
   clear_cookies        
   set_cookie "foo=quux"
   get '/'
   last_request.cookies.should == {"foo" => "quux"}
end

更新： （ it 块），您需要在执行任何测试用例之前初始化Rack会话。为此，请将之前添加到 describe 块。

Update: If you want the cookie jar to persist across the test cases (it blocks), you need to initialize the Rack session before executing any test cases. To do so, add this before hook to your describe block.

before :all do
    clear_cookies
end

b $ b

或者，您可以使用之前：每个在每个请求之前设置必要的Cookie。

Alternative, you could for example use before :each to set up the necessary cookies before each request.
