Question

我有一个以下形式的测试用例：

require 'test/unit'
class SomeTests < Test::Unit::TestCase
  def test_should_do_action
   assert true
  end
end

并按照 A Test :: Unit Trick to know About 一书中的建议，使用must重新编写它：

require 'test/unit'
class SomeTests < Test::Unit::TestCase
  must "do action" do
    assert true
  end
end

当我运行它时，我收到undefined method 'must'错误，如下所示：

SomeTests.rb:3:in `<class:SomeTests>': undefined method `must' for     SomeTests:Class (NoMethodError)  from
SomeTests.rb:2:in `<top (required)>'    from
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'   from

Tasks: TOP => default => test (See full trace by running task with --trace)

我认为must可能是minitest的一部分，所以我要求＆＃39; minitest / unit＆＃39;相反，但我仍然得到一个错误。我还假设must关键字不是rspec的一部分，我还没有使用它。

如何使其正常工作？

看起来这种方法不是开箱即用的，而是由第三方开发的。您需要添加描述here的代码。
