代码内容及解释
# ----------------------------------------------------------------------------- # Example: Test Feature Set via Python # # This sample demonstrates how to start the test modules and test # configurations via COM API using a Python script. # The script uses the included PythonBasicEmpty.cfg configuration but is # working also with any other CANoe configuration containing test modules # and test configurations. # # Limitations: # - only the first test environment is supported. If the configuration # contains more than one test environment, the other test environments # are ignored # - the script does not wait for test reports to be finished. If the test # reports are enabled, they may run in the background after the test is # finished # ----------------------------------------------------------------------------- # Copyright (c) 2017 by Vector Informatik GmbH.

*** 作实例
1-配置CANoe 工程名及该py代码与工程的相对路径
2-配置Test Module及该py代码与加载Test Module的相对路径
3-运行py代码
结果：
调试过程中遇到的问题及解决方法
Otherwise the issue of “pywintypes.com_error: (-2147352567, ‘发生意外。’, (0, None, None, None, 0, -2147467259), None)” will happen!!!
发生情况1：拟打开的CANoe工程正在运行
解决办法：确保拟打开的CANoe工程处于未运行状态
发生情况2：拟加载的Test Module（XX.tse）已经被加载到工程中了
解决办法：确保拟加载的Test Module（XX.tse）未被加载到工程中
