我在一个 ruby​​ 脚本中有 4 个测试，我使用命令运行

ruby test.rb

输出看起来像

Loaded suite test
Started
....

Finished in 50.326546 seconds.

4 tests, 5 assertions, 0 failures, 0 errors, 0 pendings, 0 omissions, 0 notifications
100% passed

我想要实现的是，并行运行所有 4 个测试，而不是按顺序运行。像 4 个线程每个运行一个测试，有效地将执行时间减少到 4 个测试中最慢的一个 + 并行执行的时间很少。

我遇到了这个，但这似乎并行运行多个 ruby​​ 测试文件 - 假设我有 test1.rb、test2.rb test3.rb，那么所有三个文件都将并行运行。

任何帮助将不胜感激。

我尝试了TestSuite和的组合Thread：

gem 'test-unit'
require 'test/unit'
require 'test/unit/ui/console/testrunner'
# we're running the tests, so we don't want Test::Unit to automatically run everything for us.  See http://www.natontesting.com/2009/07/21/stop-rubys-testunit-suite-files-running-all-your-tests/
Test::Unit.run = true


class MyTest < Test::Unit::TestCase
  def test_1()
    assert_equal( 2, 1+1)
  end
  def test_2()  
    assert_equal( 2, 4/2)
  end
  def test_3()      
    assert_equal( 1, 3/2)
  end
  def test_4()  
    assert_equal( 1.5, 3/2.0)
  end
end

#create TestSuites.
test_1 = Test::Unit::TestSuite.new("Test 1")
test_1 << MyTest.new('test_1')
#Same a bit shorter
test_2 = Test::Unit::TestSuite.new("Test 2") << MyTest.new('test_2')
test_3 = Test::Unit::TestSuite.new("Test 3") << MyTest.new('test_3')
test_4 = Test::Unit::TestSuite.new("Test 4") << MyTest.new('test_4')


#run the suites
Thread.new{Test::Unit::UI::Console::TestRunner.run(test_1)}
Thread.new{Test::Unit::UI::Console::TestRunner.run(test_2)}
Thread.new{Test::Unit::UI::Console::TestRunner.run(test_3)}
Thread.new{Test::Unit::UI::Console::TestRunner.run(test_4)}

它看起来不错，但我没有进行基准测试。

输出（见下文）有点混乱，每个线程都将他的消息发布到其他线程的消息中，但它似乎工作正常。所以也许你必须捕获每个线程的输出以获得更好的测试日志。

据说可以在 Ruby 1.9.3 中并行运行测试，但我还没有让它工作。
