Rails minitest check if record was created - ArgumentError: wrong number of arguments

Question

我有一个简单的服务，它创建了一个名为 PropertyReport:

的记录

#app/services/portfolios/related_property_reports.rb
module Portfolios
  class RelatedPropertyReports
    def initialize(portfolio, portfolio_report)
      @portfolio = portfolio
      @portfolio_report = portfolio_report
    end

    def call
      PropertyReport.create!(
        property: property,
        portfolio_report: portfolio_report,
      )
    end
  end
end

现在我想使用以下 minitest 测试此服务：

#app/services/portfolios/related_property_reports_test.rb

require 'test_helper'

module Portfolios
  class RelatedPropertyReports < ActiveSupport::TestCase
    setup do
      @portfolio = Portfolio.create(name: Faker::Bank.name)
      @property = Property.create(portfolio: @portfolio, name: Faker::Bank.name, status: 'planned')
      @portfolio_report = PortfolioReport.create(portfolio: @portfolio)
    end

    test 'create new record' do
      service.call
      assert_equal 1, PropertyReport.count
    end

    private

    def service
      @service ||= ::Portfolios::RelatedPropertyReports.new(@portfolio, @portfolio_report)
    end
  end
end

这给我一个错误：

Portfolios::RelatedPropertyReports#test_create_new_record: ArgumentError: wrong number of arguments (given 2, expected 1)

考虑到我在 new 中给出了两个参数，这太奇怪了。我错过了什么？

您需要为测试使用不同的 class 名称或模块 class。现在您正在覆盖原始 class 对象。

irb(main):001:1* module Test
irb(main):002:2*   class Test
irb(main):003:3*     def initialize(a, b)
irb(main):004:2*     end
irb(main):005:1*   end
irb(main):006:0> end
=> :initialize
irb(main):007:1* module Test
irb(main):008:2*   class Test
irb(main):009:3*     def initialize(a)
irb(main):010:2*     end
irb(main):011:3*     def service
irb(main):012:3*       ::Test::Test.new(1,2)
irb(main):013:2*     end
irb(main):014:1*   end
irb(main):015:0> end
=> :service
irb(main):016:0> Test::Test.new(1).service
(irb):9:in `initialize': wrong number of arguments (given 2, expected 1) (ArgumentError)
        from (irb):12:in `new'
