Rails测试显示0%通过时全部通过

Question

我的Rails应用程序通过了测试,但随后说0%通过了.它的Rails 3应用程序转换为3.1.

5 tests, 11 assertions, 0 failures, 0 errors, 0 pendings, 0 omissions, 0 notifications
0% passed

如果我生成一个新的Rails 3.1应用程序,它没有这个"通过"线.

1 tests, 1 assertions, 0 failures, 0 errors, 0 skips

两者都在1.9.2 p290下运行.

我试图删除测试单元,但这似乎没有什么区别,没有其他任何突出的东西会导致它.我想有些东西正在触发使用不同的测试运行器.

我已经删除了应用程序中的所有内容并将其推送到github - https://github.com/kimptoc/zero-percent-bugette 当我运行"rake"时,我仍然得到0%的通过:

如果你使用test-unitRails,那么你什么都做不了.我相信它是activesupportRails附带的gem中的一个bug .更详细:

通常,test-unit有一种方法add_pass可以增加通过的测试次数.这称为内部run(...)方法(testcase.rb文件).但是,activesupport使用自己的实现隐藏/覆盖此方法.它是run(...)文件内setup_and_teardown.rb的方法(方法的全名是ActiveSupport::Testing::SetupAndTeardown::ForClassicTestUnit#run().

我修改了这个方法如下:

    def run(result)
      return if @method_name.to_s == "default_test"

      mocha_counter = retrieve_mocha_counter(result)
      yield(Test::Unit::TestCase::STARTED, name)
      @_result = result

      begin
        begin
          _run_setup_callbacks do
            setup
            __send__(@method_name)
            mocha_verify(mocha_counter) if mocha_counter
          end
        result.add_pass # XXXXXXXXXXXX My Addition to count passed tests XXXXXXXXXX
        rescue Mocha::ExpectationError => e
          add_failure(e.message, e.backtrace)
        rescue Test::Unit::AssertionFailedError => e
          add_failure(e.message, e.backtrace)
        rescue Exception => e
          raise if PASSTHROUGH_EXCEPTIONS.include?(e.class)
          add_error(e)
        ensure
          begin
            teardown
            _run_teardown_callbacks
          rescue Test::Unit::AssertionFailedError => e
            add_failure(e.message, e.backtrace)
          rescue Exception => e
            raise if PASSTHROUGH_EXCEPTIONS.include?(e.class)
            add_error(e)
          end
        end
      ensure
        mocha_teardown if mocha_counter
      end

      result.add_run
      yield(Test::Unit::TestCase::FINISHED, name)
    end

我添加了result.add_pass哪些不存在,现在百分比应该没问题.

更新:为了帮助您集成此更改并自行测试/查看,您可以使用以下命令克隆我创建的要点:

git clone git://gist.github.com/1324512.git gist-1324512

这将创建一个名称为的文件: active_support_test_unit_pass_count.rb

将其移动到test文件所在的test_helper.rb文件夹中,并在文件中要求它test_helper.rb,恰好在ActiveSupport::TestCase类的定义之前:

require 'active_support_test_unit_pass_count'

class ActiveSupport::TestCase

....

然后运行测试并查看百分比结果.对我来说......它运作正常.
