Ruby on rails 在Mini_测试中调用任何Ruby类和未初始化常量错误

我想使用Mini_测试和Ruby实现DCI，但我无法在Mini_测试中调用AcademicYear类。我有一个简单的类和Mini_测试类，分别放在下面这样的文件中

/app/Models/academicyear.rb

class AcademicYear
  attr_accessor :year
end

require "minitest_helper"
class HeadTeacherDefineAcademicYearContextTest < MiniTest::Unit::TestCase
  def test_should_add_academic_year
    academicyear = AcademicYear.new
    academicyear.year= "2012-2013"
  end
end

/app/Test/context/headcher\u define\u academy year\u context\u Test.rb

class AcademicYear
  attr_accessor :year
end

require "minitest_helper"
class HeadTeacherDefineAcademicYearContextTest < MiniTest::Unit::TestCase
  def test_should_add_academic_year
    academicyear = AcademicYear.new
    academicyear.year= "2012-2013"
  end
end

---

我缺少什么，有什么想法吗？

你需要要求上课

require_relative '../../Models/academicyear.rb'

结果你有

/app/Test/context/headcher\u define\u academy year\u context\u Test.rb

require "minitest_helper"
require_relative '../../Models/academicyear.rb'

class HeadTeacherDefineAcademicYearContextTest < MiniTest::Unit::TestCase
  def test_should_add_academic_year
    academicyear = AcademicYear.new
    academicyear.year= "2012-2013"
  end
end

需要“minitest\u助手”
需要_relative'../../Models/academicyear.rb'
类头教师defineAcademicyearContextTest
