Question

我是Rspec的新手。我写了一个rspec来检查名为“Lead controller”的控制器的创建动作。现在我想编写一个规范，检查名为“status”的属性设置为“LEAD”。我想在创建潜在客户后从应用程序的帖子数据中检查它。如何使用'expect'块和'post：create'来检查状态？

describe 'POST #create' do
    it "should create a lead" do
      my_lead = Fabricate(:project, id:  Faker::Number.number(10))
      expect{
      post :create, project: my_lead.attributes
      }.to change(Project, :count).by(1)
    end
     it "should assign the status to lead" do
       my_lead = Fabricate(:project, id:  Faker::Number.number(10))
       my_lead.status.should == "LEAD"
     end

  end

Answer 1

您的第二个测试必须测试创建对象的状态是否按预期设置：

describe '#create' do
  let!(:my_lead) { Fabricate(:project, id:  Faker::Number.number(10)) }

  it "should create a lead" do
    expect{ post :create, project: my_lead.attributes }
      .to change(Project, :count).by(+1)
  end

  it "should assign the status to lead" do
    post :create, project: my_lead.attributes
    expect(Project.last.status).to eq('LEAD')
  end
end

您可以使用assigns(:instance_variable_name)方法访问控制器中已分配的实例变量。

例如，假设您的create操作如下所示：

def创建 @lead = Project.create（project_params）端

然后，您可以通过调用@lead访问RSpec控制器示例中的assigns(:lead)。请注意，符号文本与实例变量名称完全匹配。

因此，您更新的测试看起来像这样：

 it "should assign the status to lead" do
   my_lead = Fabricate(:project, id:  Faker::Number.number(10))

   post :create, project: my_lead.attributes

   # Test that the status for @lead in our controller matches what we expect it to:
   assigns(:lead).status.should == "LEAD"
 end

最后，我想出了一个小问题，解决了我的问题

describe 'POST #create' do
    it "should create a lead" do
      my_lead = Fabricate(:project, id:  Faker::Number.number(10))
      expect{
      post :create, project: my_lead.attributes
      }.to change(Project, :count).by(1)
    end
    it "should assign the status to lead" do
      my_lead = Fabricate(:project, id:  Faker::Number.number(10))
      post :create, project: my_lead.attributes
      expect(Project.last.status).to eq('LEAD')
    end
  end

Rspec测试检查创建对象的值
