Question

我正在使用rake任务来运行用Ruby编写的测试。佣金任务：

desc "This Run Tests on my ruby app"
Rake::TestTask.new do |t|
  t.libs << File.dirname(__FILE__)
  t.test_files = FileList['test*.rb']
  t.verbose = true
end

我想创建一个超时，以便在任何测试（或整个套件）挂起时，将抛出超时异常并且测试将失败。

我尝试创建一个新任务，以超时运行测试任务：

desc "Run Tests with timeout"
task :run_tests do
  Timeout::timeout(200) do
    Rake::Task['test'].invoke
  end
end

结果是抛出了超时，但测试继续运行。

我一直在寻找类似的东西，最终写成这样：

require 'timeout'

# Provides an individual timeout for every test.
#
# In general tests should run for less then 1s so 5s is quite a generous timeout.
#
# Timeouts can be overridden per-class (in rare cases where tests should take more time)
# by setting for example `self.test_timeout = 10 #s`
module TestTimeoutHelper
  def self.included(base)
    class << base
      attr_accessor :test_timeout
    end

    base.test_timeout = 5 # s
  end

  # This overrides the default minitest behaviour of measuring time, with extra timeout :)
  # This helps out with: (a) keeping tests fast :) (b) detecting infinite loops
  #
  # In general however benchmarks test should be used instead.
  # Timeout is very unreliable by the way but in general works.
  def time_it
    t0 = Minitest.clock_time

    Timeout.timeout(self.class.test_timeout, Timeout::Error, 'Test took to long (infinite loop?)') do
      yield
    end
  ensure
    self.time = Minitest.clock_time - t0
  end
end

此模块应包含在特定的测试用例或一般的测试用例中。

它与MiniTest 5.x兼容

此代码为整个套件添加超时：

def self.suite
    mysuite = super
    def mysuite.run(*args)
        Timeout::timeout(600) do
            super
        end
    end
    mysuite
end

将超时设置为ruby Test :: unit run
