并行运行时，Ruby 1.9.3 不运行任何单元测试

给定以下代码，

# Modified from https://gist.github.com/1334056/121396125ca4dd7ee1bb81536cce0754700f20fb
# replication.rb
require 'test/unit'
class TestTest < Test::Unit::TestCase
  def test_one
    assert true
  end

  def test_two
    assert true
  end
end

单元测试在不并行运行时有效，但在并行运行时无效：

$ ruby1.9.1 replication.rb 
Run options: 

# Running tests:

对于它的价值，以下是调试开关打开时发生的情况：

我也尝试过要求 minitest，但没有可用的并行测试：

# mini_me.rb
# modified from http://apidock.com/ruby/MiniTest
require 'minitest/autorun'

class TestMeme < MiniTest::Unit::TestCase
  def test_one
    assert true
  end

  def test_two
    assert true
  end
end

给

$ ruby1.9.1 mini_me.rb --help
minitest options:
    -h, --help                       Display this help.
    -s, --seed SEED                  Sets random seed
    -v, --verbose                    Verbose. Show progress processing files.
    -n, --name PATTERN               Filter test names on pattern.

这是 Ruby 和 ubuntu 的版本。

$ ruby1.9.1 --version
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]

$ uname -a
Linux [redacted] 3.2.0-24-generic #37-Ubuntu SMP Wed Apr 25 08:43:22 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

我还使用最近提交的 Ruby on OS X snow leopard (ruby 2.0.0dev (2012-05-05 trunk 35543) [x86_64-darwin10.8.0]) 运行了第一个脚本，但它在那里不起作用。

我究竟做错了什么？

当我有多个文件但未明确使用时会发生以下情况Test::Unit::Runner

测试1.rb

require "test/unit"

class Test1 < Test::Unit::TestCase
  def test_one
    assert true
  end
end

test2.rb

require "test/unit"

class Test2 < Test::Unit::TestCase
  def test_two
    assert true
  end
end

test_all.rb

require_relative "test1"
require_relative "test2"

尝试使用这种方法：

$ ruby test_all.rb --basedir=. --jobs 2 --ruby /Users/agrimm/.rvm/rubies/ruby-head/bin/ruby
Run options: --basedir=. --jobs 2 --ruby /Users/agrimm/.rvm/rubies/ruby-head/bin/ruby

我是 sora_h 的维护者test/unit。

test/unit为每个测试文件并行化。

您需要分离测试文件并TestCase进行并行化。

很抱歉给您带来不便，但我们无法为每个test_*方法并行化，因为有些test_*方法不能单独运行。（需要订购）

您可以使用Test::Unit::Runner来运行多个文件。

谢谢你。
