Question

我正在尝试创建一个xml运行器来生成Rails单元测试的结果报告。这是我的代码：

require 'test/unit'
require 'test/unit/ui/console/testrunner'

class FastFailRunner < Test::Unit::UI::Console::TestRunner
  def add_fault(fault)
    @faults << fault
    nl
    output("%3d) %s" % [@faults.length, fault.long_display])
    output("--")
    @already_outputted = true
  end

  def finished(elapsed_time)
    nl
    output("Finished in #{elapsed_time} seconds.")
    nl
    output(@result)
  end
end

Test::Unit::AutoRunner::RUNNERS[:fastfail] = proc do |r|
  FastFailRunner
end

当我以TESTOPTS="/home/alex/RubymineProjects/app2/test/unit/runner.rb --runner=xml" rake test

运行时

...我收到错误（非常奇怪的错误）

我试图要求test/unit/ui/xml/testrunner.rb，但没有运气。有什么想法吗？

Answer 1

如果你在Ruby 1.8.7中，你可以说：

require 'test/unit/ui/console/testrunner'
p Test::Unit::UI::Console::TestRunner # => no problem

（没有test/unit/ui/xml/testrunner.rb这样的文件，所以我不确定你在那里做什么。）

查看test / unit.rb中的文档，实际上有示例代码向您展示如何执行此操作：http://www.ruby-doc.org/stdlib-1.8.7/libdoc/test/unit/rdoc/Test/Unit.html。

然而，问题是你在Ruby 1.9.3中。 Ruby 1.9.3中没有/ test / unit！嗯，有，但它只是基本测试的兼容层;肯定没有test / unit / ui / console / testrunner，也没有模块/类Test::Unit::UI::Console::TestRunner。

相反，它是最小的。您可以阅读minitest上的文档，了解如何制作测试运行器。 http://docs.seattlerb.org/minitest/

要考虑的一件事是Test :: Unit包含在默认的Ruby 1.8.7安装中。如果你想在更高版本的Ruby中使用它，那就继续安装它作为gem。

sudo gem install test-unit

http://test-unit.rubyforge.org/

Rails（或Ruby）中未初始化的常量Test :: Unit :: UI :: XML（NameError）
