Rails/Rspec - testing a redirect in the controller
提问by TheLegend
So I am currently writing a test for a controller in an existing controller that just didn't have one before. What I want to test is a redirect that happens when someone is not allowed to edit something vs someone that is allowed to edit it.
因此，我目前正在为之前没有的现有控制器中的控制器编写测试。我想测试的是当不允许某人编辑某些内容与允许对其进行编辑的某人时发生的重定向。
the controller action being edit
正在编辑的控制器动作
def edit
if [email protected]? || admin?
@company = @scorecard.company
@custom_css_include = "confirmation_page"
else
redirect_to :back
end
end
So if a scorecard has been reviewed then only an admin can edit that score. The routes for that controller..
因此，如果已审核记分卡，则只有管理员才能编辑该分数。该控制器的路由..
# scorecards
resources :scorecards do
member do
get 'report'
end
resources :inaccuracy_reports, :only => [:new, :create]
end
and finally the test
最后是测试
require 'spec_helper'
describe ScorecardsController do
describe "GET edit" do
before(:each) do
@agency = Factory(:agency)
@va = Factory(:va_user, :agency => @agency)
@admin = Factory(:admin)
@company = Factory(:company)
@scorecard = Factory(:scorecard, :level => 1, :company => @company, :agency => @agency, :reviewed => true)
request.env["HTTP_REFERER"] = "/scorecard"
end
context "as a admin" do
before(:each) do
controller.stub(:current_user).and_return @admin
end
it "allows you to edit a reviewed scorecard" do
get 'edit', :id => @scorecard.id
response.status.should be(200)
end
end
context "as a va_user" do
before(:each) do
controller.stub(:current_user).and_return @va
end
it "does not allow you to edit a reviewed scorecard" do
get 'edit', :id => @scorecard.id
response.should redirect_to :back
end
end
end
end
so a va when trying to edit a reviewed score will be redirected back, where an admin won't.
因此，尝试编辑已审核分数时的 va 将被重定向回，而管理员则不会。
but when running this through rspec I get
但是当通过 rspec 运行它时，我得到
ScorecardsController
GET edit
as a admin
allows you to edit a reviewed scorecard
as a va_user
does not allow you to edit a reviewed scorecard (FAILED - 1)
Failures:
1) ScorecardsController GET edit as a va_user does not allow you to edit a reviewed scorecard
Failure/Error: response.should redirect_to :back
Expected response to be a redirect to </scorecard> but was a redirect to <http://test.host/>
# ./spec/controllers/scorecards_controller_spec.rb:33:in `block (4 levels) in <top (required)>'
Finished in 0.48517 seconds
2 examples, 1 failure
so I don't know if its working or not since I set the request.env["HTTP_REFERER"] = "/scorecard"as the place that should be the :backas it where. or am I missing the idea all together looking at httpstatusthere are the 300 responses that I could use but I wouldn't know where to start?
所以我不知道它是否有效，因为我将它设置request.env["HTTP_REFERER"] = "/scorecard"为应该:back作为它的地方。或者我是否在看httpstatus时错过了这个想法，那里有 300 个我可以使用的回复，但我不知道从哪里开始？
any help would be awesome
任何帮助都是极好的
EDIT
编辑
I could test it by doing it like this
我可以通过这样做来测试它
...
response.status.should be(302)
but I got the idea from this questionand it sounds like this could be powerful as it specifies the url redirected to.
但我从这个问题中得到了这个想法，听起来这可能很强大，因为它指定了重定向到的 url。
Anyone have a working test like this?
有人有这样的工作测试吗？

This line has problem
这条线有问题
response.should redirect_to :back
The logic is not correct. You should expect #editto redirect to :backpath you set before, which is /scorecard. But you set :backhere. In the context of Rspec, :backshould be empty at each example.
逻辑不正确。您应该期望#edit重定向到:back您之前设置的路径，即/scorecard. 但是你设置:back在这里。在 Rspec 的上下文中，:back在每个示例中都应为空。
To revise, just set it as
要修改，只需将其设置为
response.should redirect_to '/scorecard'

To make the test more readable you can do this: (rspec ~> 3.0)
为了使测试更具可读性，您可以这样做：（rspec ~> 3.0）
expect(response).to redirect_to(action_path)
回答by aldrien.h
For testing if redirects happened, with no matching route
用于测试重定向是否发生，没有匹配的路由
(just to test redirection, i used this when route is too long :D ). You can simply do like:
（只是为了测试重定向，我在路由太长时使用了这个：D）。您可以简单地执行以下操作：
expect(response.status).to eq(302) #redirected
