pycharm下运行unittest的问题

环境:

系统:window7 64 

软件:pycharm

版本:2016.3.2

问题描述:

使用unittest类的时候出现问题,问题截图如下

Pycharm 2016.2执行单元测试遇到如下问题:

RuntimeWarning: Parent module ‘YOUR_MODULE_HERE’ not found while handling absolute import 
import unittest

解决方法,使用旧的utrunner.py文件替换当前版本,文件路径为…/PyCharm.app/Contents/helpers/pycharm/utrunner.py(macos平台)或者…JetBrainsPyCharm 2016.2.2helperspycharmutrunner.py(windows平台)。utrunner.py的内容如下(替换文件前请先做好备份):

utrunner.py如下:
