Rails 3.1 Rspec Rails 2 - 如何测试此控制器操作？

Question

我需要知道如何测试这个控制器动作

  def create_mobile
      if mobile_user = MobileUser.authenticate(params[:email], params[:password])
        session[:mobile_user_id] = mobile_user.id
        respond_to do |format|
          format.json { head :ok }
        end
      else
        respond_to do |format|
          format.json { head :unauthorised }
        end
      end
  end

该路由是对sessions/create_mobile的发布请求,您可以看到该操作仅响应json

我当前的控制器规格看起来像这样

describe SessionsController, "Logging in" do

  before(:each) do
    @mobile_user = FactoryGirl.create(:valid_mobile_user)
  end

  it "Should log in mobile user" do
    @request.env["HTTP_ACCEPT"] = "application/json"
    post :create_mobile, {:password => @mobile_user.password, :email => @mobile_user.email}
    response.should be_success
  end

  it "should fail log in mobile user" do
    @request.env["HTTP_ACCEPT"] = "application/json"
    post :create_mobile, {:password => 'joe', :email => @mobile_user.email}
    response.should_not be_success
  end

结束

测试结果如下

  1) SessionsController Logging in should log in mobile user
     Failure/Error: response.should be_success
       expected success? to return true, got false
     # ./spec/controllers/sessions_controller_spec.rb:11:in `block (2 levels) in <top (required)>'

所以我的应用程序代码有问题或我的测试代码出现问题,但无论哪种方式,authenticate方法都没有问题,因为MobileUser模型规范通过,看起来像这样

  it "should authenticate" do
    mu = FactoryGirl.create(:valid_mobile_user)
    assert_equal 1, MobileUser.count
    assert_equal mu, MobileUser.authenticate(mu.email, mu.password)

  end

任何帮助整理这一点非常感谢.提前致谢

更新 如下所述,使用

post :create_mobile, {:password => 'joe', :email => @mobile_user.email} :format => :json

或使用

@request.env["HTTP_ACCEPT"] = "application/json"

或两者的结合没有区别

更新2 测试刚刚开始工作,我无法理解(除了我从来没有理解为什么它不起作用).完全奇怪!

Answer 1

我最近遇到了同样的问题.下面是我的测试代码

post :create, :login => 'mock_user', :password => 'passwd', :format => :json

expected = {
    :login => 'mock_user'
}.to_json

session[:user_id].should == mock_user.id
response.body.should == expected

测试结果为false,由response.body为空.我检查了test.log,发现控制器中出现406不可接受的请求错误.经过google搜索后,我改为:format =>'json'.然后我得到了预期的测试结果.
