Question

现在，我的组织控制器会列出当前用户拥有会员资格的所有组织。我知道我的测试是错误的，但我无法弄清楚它是如何正确的。

organizations_controller.rb

def index
   @user = current_user
   @organizations = @user.organizations.all
end

这样工作正常，模型正常，视图显示正确的组织。

我正在尝试为它编写测试，但不知怎的，我被卡住了。这是我的工厂：

  factory :organization do 
    name "example"
    website "www.aquarterit.com"
    after(:create) {|organization| organization.users = [create(:admin)]}
  end

这是我的测试：

describe "GET #index" do 
    it "populates an array of organizations where the user has membership" do
        organization = create(:organization)
        get :index
        expect(assigns(:organizations)).to eq([organization])
    end
    it "renders the :index view"  do
        get :index
        expect(response).to render_template ("index")
    end
end

结果很自然：

expected: [#<Organization id: 1, name: "example", website: "www.aquarterit.com", created_at: "2014-02-20 22:10:17", updated_at: "2014-02-20 22:10:17">]
            got: nil

       (compared using ==)

这是因为您在测试中创建的organization与调用user时返回的current_user无关。存根current_user方法以返回您的用户

describe "GET #index" do 
    it "should populate an array of organizations where the user has membership" do
        organization = create(:organization)
        controller.stub(:current_user).and_return(organization.user)
        get :index
        expect(assigns(:organizations)).to eq([organization])
    end

    it "renders the :index view"  do
        get :index
        expect(response).to render_template ("index")
    end
end
