在 RSpec 中存根 RestClient 响应

我有以下规格...

  describe "successful POST on /user/create" do
    it "should redirect to dashboard" do
      post '/user/create', {
          :name => "dave",
          :email => "[email protected] /cdn-cgi/l/email-protection",
          :password => "another_pass"
      }
      last_response.should be_redirect
      follow_redirect!
      last_request.url.should == 'http://example.org/dave/dashboard'
    end
  end

Sinatra 应用程序上的 post 方法使用rest-client 调用外部服务。我需要以某种方式存根其余客户端调用以发回预设响应，这样我就不必调用实际的 HTTP 调用。

我的应用程序代码是...

  post '/user/create' do
    user_name = params[:name]
    response = RestClient.post('http://localhost:1885/api/users/', params.to_json, :content_type => :json, :accept => :json)
    if response.code == 200
      redirect to "/#{user_name}/dashboard"
    else
      raise response.to_s
    end
  end

有人可以告诉我如何使用 RSpec 做到这一点吗？我用谷歌搜索了一下，发现很多博客文章都触及了表面，但我实际上找不到答案。我对 RSpec 时期还很陌生。

Thanks

Using a mock https://relishapp.com/rspec/rspec-mocks/docs对于响应，你可以这样做。一般来说，我对 rspec 和测试还很陌生，但这对我有用。

describe "successful POST on /user/create" do
  it "should redirect to dashboard" do
    RestClient = double
    response = double
    response.stub(:code) { 200 }
    RestClient.stub(:post) { response }

    post '/user/create', {
      :name => "dave",
      :email => "[email protected] /cdn-cgi/l/email-protection",
      :password => "another_pass"
    }
    last_response.should be_redirect
    follow_redirect!
    last_request.url.should == 'http://example.org/dave/dashboard'
  end
end
