ruby - 如何使用 rspec 在 sinatra 中测试重定向？

Question

我正在尝试在 rspec 中测试我的 sinatra 应用程序（更具体地说，一个 padrino 应用程序）的主页上的重定向。我找到了redirect_to，但它似乎只在 rspec-rails 中。你如何在 sinatra 中测试它？

所以基本上，我想要这样的东西：

  it "Homepage should redirect to locations#index" do
    get "/"
    last_response.should be_redirect   # This works, but I want it to be more specific
    # last_response.should redirect_to('/locations') # Only works for rspec-rails
  end

Answer 1

试试这个（未测试）：

it "Homepage should redirect to locations#index" do
  get "/"
  last_response.should be_redirect   # This works, but I want it to be more specific
  follow_redirect!
  last_request.url.should == 'http://example.org/locations'
end

Answer 2

更直接地，您可以使用 last_response.location。

it "Homepage should redirect to locations#index" do
  get "/"
  last_response.should be_redirect
  last_response.location.should include '/locations'
end

Answer 3

在新expect语法中，它应该是：

it "Homepage should redirect to locations#index" do
  get "/"
  expect(last_response).to be_redirect   # This works, but I want it to be more specific
  follow_redirect!
  expect(last_request.url).to eql 'http://example.org/locations'
end
