Rspec 测试 redirect_to :back [英] Rspec testing redirect_to :back

问题描述

你如何在 rspec 中测试 redirect_to :back?

How do you test redirect_to :back in rspec?

我明白了

ActionController::RedirectBackError:
在此操作的请求中未设置 HTTP_REFERER，因此无法成功调用 redirect_to :back.如果这是一个测试，请确保指定 request.env["HTTP_REFERER"].

ActionController::RedirectBackError:
No HTTP_REFERER was set in the request to this action, so redirect_to :back could not be called successfully. If this is a test, make sure to specify request.env["HTTP_REFERER"].

如何在测试中设置 HTTP_REFERER?

推荐答案

使用 RSpec，您可以在 before 块中设置引用.当我尝试在测试中直接设置引用者时，无论我把它放在哪里，它似乎都不起作用，但是 before 块可以解决问题.

Using RSpec, you can set the referer in a before block. When I tried to set the referer directly in the test, it didn't seem to work no matter where I put it, but the before block does the trick.

describe BackController < ApplicationController do
  before(:each) do
    request.env["HTTP_REFERER"] = "where_i_came_from"
  end

  describe "GET /goback" do
    it "redirects back to the referring page" do
      get 'goback'
      response.should redirect_to "where_i_came_from"
    end
  end
end
