Unittest Framework 简明教程

UnitTest Framework - Time Test

Java 单元测试框架 Junit（Pyunit 是 JUnit 的实现）有一个便捷的超时选项。如果测试花费的时间超过指定的时间，则该测试将标记为失败。

Junit, the Java unit testing framework (Pyunit is implementation of JUnit) has a handy option of timeout. If a test takes more than specified time, it will be marked as failed.

Python 的测试框架不包含任何超时支持。但是，一个名为 timeout-decorator 的第三方模块可以完成该作业。

Python’s testing framework doesn’t contain any support for time out. However, a third part module called timeout-decorator can do the job.

从以下位置下载并安装该模块 −

Download and install the module from −

https://pypi.python.org/packages/source/t/timeout-decorator/timeout-decorator-0.3.2.tar.gz

Import timeout_decorator in the code
Put timeout decorator before the test
@timeout_decorator.timeout(10)

如果这个时间段中的测试方法超过这里提到的超时（10 分钟），将会引发 TimeOutError。例如 −

If a test method below this line takes more than the timeout mentioned (10 mins) here, a TimeOutError will be raised. For example −

import time
import timeout_decorator

class timeoutTest(unittest.TestCase):

   @timeout_decorator.timeout(5)
   def testtimeout(self):
      print "Start"
   for i in range(1,10):
      time.sleep(1)
      print "%d seconds have passed" % i

if __name__ == '__main__':
   unittest.main()
