Ruby on rails 测试控制器方法。Rspec

Ruby on rails 测试控制器方法。Rspec,ruby-on-rails,ruby,rspec,rspec-rails,Ruby On Rails,Ruby,Rspec,Rspec Rails,我想测试控制器方法,但我找不到带有顺序和搜索的测试方法示例。 这是我的控制器: class Admin::HotelsController < Admin::BaseController helper_method :sort_column, :sort_direction def index @hotels = Hotel.search(params[:search], params[:search_column]).order(sort_column + ' ' + s

我想测试控制器方法,但我找不到带有顺序和搜索的测试方法示例。 这是我的控制器:

class Admin::HotelsController < Admin::BaseController
  helper_method :sort_column, :sort_direction
  def index
    @hotels = Hotel.search(params[:search], params[:search_column]).order(sort_column + ' ' + sort_direction)
  end

  def show
    @hotel = Hotel.find(params[:id])

  end

  def update
    @hotel = Hotel.find(params[:id])
    if @hotel.update_attributes(hotel_params)
      redirect_to admin_hotels_path
    else
      render(:edit)
    end
  end

private
  def hotel_params
    params.require(:hotel).permit(:title, :description, :user_id, :avatar, :price, :breakfast, :status, address_attributes: [:state, :country, :city, :street])
  end

  def sort_column
    Hotel.column_names.include?(params[:sort]) ? params[:sort] : 'created_at'
  end

  def sort_direction
    %w[asc desc].include?(params[:direction]) ? params[:direction] : 'asc'
  end
end 
我不知道如何测试索引方法。请帮助我或给我一个关于这个信息的链接。谢谢

我建议使用

describe 'GET index' do
  let(:hotel1) { create(:hotel) }
  let(:hotel2) { create(:hotel) }

  it 'render index template' do
    get :index
    expect(response).to render_template :index
  end

  it 'render asc ordered hotels' do
    get :index

    # if you are using json responses
    json = JSON.parse(response.body) 
    expect(json['hotels'].first).to eq hotel1
    expect(json['hotels'].last ).to eq hotel2
    # or any similar approach to get test the hotels in response
  end

  it 'render desc ordered hotels' do
    get :index, {direction: 'desc'}

    # if you are using json responses
    json = JSON.parse(response.body) 
    expect(json['hotels'].first).to eq hotel2
    expect(json['hotels'].last ).to eq hotel1
    # or any similar approach to get test the hotels in response
  end

  # you can complete these tests yourself
  it 'render hotels sorted with different_column_than_created_at asc'
  it 'render hotels sorted with different_column_than_created_at desc'

end

  let(:hotel1) { create(:hotel) }
  let(:hotel2) { create(:hotel) }

如果可能对您有所帮助,出于各种原因,我个人更喜欢对控制器进行最低限度测试:

1) 当我开始rails测试时,我读了很多文章说这是个好主意 2) 它允许您在隔离模型方法中进行测试:

describe 'GET index' do
  it 'render a list of hotels' do
    hotel1, hotel2 = create(:hotel), create(:hotel)
    get :index
    expect(assigns(:hotels)).to match_array([hotel1, hotel2])
  end
end 
这里,您的测试与您对模型的查询结果相匹配。您可以像这样拆分它:

describe 'GET index' do
  it 'render a list of hotels' do
    hotel1, hotel2 = create(:hotel), create(:hotel)
    Hotel.should_receive(:search).with(YOUR PARAMS)
    get :index
    response.response_code.should == 200
  end
end
context "" do
  before(:each) do
    @hotel = create(:hotel)   # here the @ is necessary for the variable to be        
    end                       # accessible in the it
  it "" do
  end
end
然后在模型测试中测试Hotel.search的结果

3) 它允许您测试功能,而不是一些不相关的随机事件:

describe 'GET show' do
  it 'should show hotel' do
    @hotel = create(:hotel)
    get :show, { id: @hotel.to_param, template: 'hotels/show' }
    expect(response).to render_template :show
  end
end
这里的“expect(response).to render_template:show”似乎是在测试rails呈现系统是否正常工作。我假设这不是您想要测试的,您可能更喜欢(我会这么做):

然后使用类似于capybara gem的功能测试测试web页面上应该显示的内容,除非您呈现一些json:在本例中,匹配控制器中的json值

顺便说一下:“@hotel=create(:hotel)”这里不需要@,因为您在“it”中。此外,您还可以创建这样的条目:

describe 'GET index' do
  it 'render a list of hotels' do
    hotel1, hotel2 = create(:hotel), create(:hotel)
    Hotel.should_receive(:search).with(YOUR PARAMS)
    get :index
    response.response_code.should == 200
  end
end
context "" do
  before(:each) do
    @hotel = create(:hotel)   # here the @ is necessary for the variable to be        
    end                       # accessible in the it
  it "" do
  end
end
甚至像这样:

context "" do
  let(:hotel) { create(:hotel) } # you can call it in the test by using hotel and it
  it "" do                       # will be insert in you db only when it's in the "it"
  end                            # if you want it to be created in the "it" without
end                              # calling hotel for nothing, use let!

尝试使用
eq
而不是
match\u array
。谢谢,它们的不同之处在于,即使是部分匹配,match\u array也会返回true?是的替代形式,它不关心顺序。尝试使用

响应.body
,因为我添加了json部分作为示例来了解这个想法。。。与实际代码不同。。。因此,如果您发布
response.body
我可能可以编辑答案如何操作,请告诉我?只需在
get:index

@json=……
之前添加
p response.body
