Question

可能重复：
rspec - why does this attribute comparison usng assert_equal fail when they are the same, on ubuntu only?

Ruby: 1.9.3-p194  
Rails: 3.2.8  
Ubuntu: 12.04

测试有很多设置，然后最终确实：

assert_equal @iep_service.attributes, IepService.first.attributes

在Mac上运行但在ubuntu上失败：

如果有帮助，完整的来源是：

context "A typical district" do
  before(:each) { set_up_district }

  context "With pre-existing students" do
    before(:each) { StudentSpreadsheet.new(@district, open_spec_fixture_file('sample-students.csv')) }

    context "And a pre-existing Iep Service for one of those students" do
      before(:each) { @iep_service = FactoryGirl.create(:iep_service, :student => @district.students.first) }

      context "And an Iep Service CSV" do
        before(:each) { @spreadsheet = IepServiceSpreadsheet.new(@district, open_spec_fixture_file('sample-ieps.c    sv')) }
        specify "Prevent importing" do
          # Leave database untouched
          assert_equal 1, IepService.count
          assert_equal @iep_service.attributes, IepService.first.attributes

          # Provide error report
          assert @spreadsheet.error_report.any?
        end
      end
    end
  end
end

assert_equal使用operator / method ==。

您可以在此处阅读assert_equal的文档：http://ruby-doc.org/core/classes/Test/Unit/Assertions.html#M006665。它直接来自Ruby，Rails不会覆盖定义。

因此，取决于对象类型== bahaves的不同，以及它来自Ruby，可能会有不同的实现或ruby代码略有不同。

无论如何，你最好比较一个值或者与==比较可能会带给你的。

rspec - 为什么这个assert_equal比较测试在mac上而不在Ubuntu上工作？
