Ruby on rails Rspec将视图参数传递给控制器规范

我的问题是，我试图通过使用rspec获得尽可能多的覆盖率，但我无法测试某些行。我试图将params散列传递给我的rspec中的controller方法，以模拟视图中的值。基本上，这些值将过滤显示在我的索引页面上的结果

我正在测试的控制器方法是：

 def index
@buildings = Building.all

@buildings = @buildings.searchaddress(params[:searchaddress])


if params[:searchcompany] != nil
  @buildings = @buildings.searchcompany(params[:searchcompany][:management])
end

if params[:searchcompany] != nil
  @buildings = @buildings.searchcity(params[:searchcity][:city])
end

if params[:searchparking] == 'on'
  params[:searchparking] = 't'
  @buildings = @buildings.searchparking(params[:searchparking])
end

if params[:searchpets] != nil 
  params[:searchpets] = 't'
  @buildings = @buildings.searchpets(params[:searchpets])
end

结束

我正在尝试通过rspec测试中的参数哈希。我尝试了几种方法，包括这一种：

describe "viewing all buildings" do
    it "renders index template" do

        param = Hash.new()
        param[:searchcompany] = [management:'asdf']
        param[:searchcity] = [city:'asdf']    #have also tried {city:""}
        param[:searchparking] = ['on']
        param[:searchpets] = [true]
        param[:searchaddress] = ['lalala']

        get :index, params:param #{searchcompany:{management:'asdf'}, searchcity:{city:'asdf'}, searchparking:'on', searchpets:true}
        expect(response).to render_template('index')
        expect(assigns(:buildings)).to be_truthy


        expect(Building).to receive(Building.searchcompany)
        expect(Building).to receive(Building.searchcity)
        expect(Building).to receive(Building.searchpets)
        expect(Building).to receive(Building.searchparking)
    end
   end

searchpets、searchcompany等方法来自我的建筑模型，并按如下方式实现

def self.searchaddress(search)
where("address LIKE ?", "%#{search}%") 
end

以下是我得到的错误：

 1) BuildingsController viewing all buildings renders index template
 Failure/Error:
   def self.searchcity(search)
     where("city LIKE ?", "%#{search}%")

 ArgumentError:
   wrong number of arguments (0 for 1)
 # ./app/models/building.rb:39:in `searchcity'
 # ./spec/controllers/buildings_controller_spec.rb:103:in `block (3 levels) in <top (required)>'

1）BuildingController查看所有建筑物渲染索引模板
失败/错误：
定义self.searchcity（搜索）
何处（“城市式？”，“%#{search}%”）
参数错误：
参数数目错误（0表示1）
#/app/models/building.rb:39:in'searchcity'
#./spec/controller/buildings\u controller\u spec.rb:103:in'block（3层）in'

如何通过rspec测试将[:searchcity][:city]传递给我的控制器方法？

您可以尝试：

 it "renders index template" do
    params = {
      searchcompany: {
        management: 'asdf'
      },
      searchcity: {
        city: 'asdf'
      },
      searchparking: 'on'
    }
    # All your expectations like 'expect(sth).to receive(:method)' go here
    get :index, params
    # Your remaining expectations go here
 end
