Ruby on rails RubyonRails控制器测试失败

除了一些其他的失败之外，我主要在这里看到：

FAIL["test_should_create_kiga", Minitest::Result, 1.6827512969975942]
test_should_create_kiga#Minitest::Result (1.68s)
    "Kiga.count" didn't change by 1.
    Expected: 4
      Actual: 3
    test/controllers/kigas_controller_test.rb:20:in `block in <class:KigasControllerTest>'

app/test/controllers/kigas\u controller\u test.rb

require 'test_helper'

class KigasControllerTest < ActionDispatch::IntegrationTest
 setup do
  @kiga = kigas(:one)
  @other_kiga = kigas(:two)
 end
[...]
 test "should create kiga" do
  assert_difference('Kiga.count') do
   post kigas_url, params: { kiga: { accessible: @kiga.accessible, add_number: @kiga.add_number, allday: @kiga.allday, capacity: @kiga.capacity, city: @kiga.city, halalkit: @kiga.halalkit, koschakit: @kiga.koschakit, name: @kiga.name, postalcode: @kiga.postalcode, streed: @kiga.streed, vegankit: @kiga.vegankit, vegekit: @kiga.vegekit, user_id: @kiga.user_id } }
 end

  assert_redirected_to kiga_url(Kiga.last)
 end
[...]
end

需要“测试助手”
类KigasControllerTest

app/controllers/kigas_controller.rb

class KigasController < ApplicationController
before_action :set_kiga, only: [:show, :edit, :update, :destroy]
before_action :logged_in_user
 def create
   @kiga = Kiga.new kiga_params
   @kiga.user = current_user
   @kiga.save
   respond_to do |format|
     if @kiga.save
       format.html { redirect_to @kiga, notice: 'Kiga was successfully created.' }
       format.json { render :show, status: :created, location: @kiga }
     else
       format.html { render :new }
       format.json { render json: @kiga.errors, status: :unprocessable_entity }
     end
   end
 end
end

class KigasController

所以我的问题是，我不知道为什么这个测试在create测试中需要四个kigas，因为我在.yml文件中有三个样本。我的应用程序中的一些其他对象也有同样的问题，所以这可能是我在这里面临的一个基本问题？

我很高兴能得到任何帮助！

它需要四个kigas，因为这是

断言差异

方法的工作方式。它需要+1个记录量。请检查此答案：
现在的问题是，你的

后kigas\u url

没有创建新的kiga，也许你的kiga模型中有某个验证没有通过

class KigasController < ApplicationController
before_action :set_kiga, only: [:show, :edit, :update, :destroy]
before_action :logged_in_user
 def create
   @kiga = Kiga.new kiga_params
   @kiga.user = current_user
   @kiga.save
   respond_to do |format|
     if @kiga.save
       format.html { redirect_to @kiga, notice: 'Kiga was successfully created.' }
       format.json { render :show, status: :created, location: @kiga }
     else
       format.html { render :new }
       format.json { render json: @kiga.errors, status: :unprocessable_entity }
     end
   end
 end
