ruby – Rails测试显示0％通过时全部通过

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.@H_403_5@

1 tests,1 assertions,0 skips

两者都在1.9.2 p290下运行.@H_403_5@

我试图删除测试单元,但这似乎并没有什么区别,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.@H_403_5@

解决方法

如果您使用带有Rails的测试单元,那么您将无法执行任何操作.我相信它是Rails附带的activesupport gem中的一个错误.更详细：

通常,测试单元有一个方法add_pass,可以增加通过的测试计数.这称为run(…)方法(testcase.rb文件).但是,activesupport会使用自己的实现隐藏/覆盖此方法.它是文件setup_and_teardown.rb中的方法run(…)(方法的全名是ActiveSupport :: Testing :: SetupAndTeardown :: ForClassicTestUnit#run().@H_403_5@

我修改了这个方法如下：@H_403_5@

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

我添加了不存在的result.add_pass,现在百分比应该没问题.@H_403_5@

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：@H_403_5@

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

这将创建一个名为active_support_test_unit_pass_count.rb的文件@H_403_5@

将其移至test_helper.rb文件所在的测试文件夹,并在test_helper.rb文件中将其移至需要它,正好在ActiveSupport :: TestCase类的定义之前：@H_403_5@

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.@H_403_5@
