我定义了以下异常：
for const in btnSound.constraints {
if const.identifier == "constBtnSound" {
...
}
}
现在，我在通过class ArgumentsException(Exception):
"""Exception that is raised when incorrect arguments are used."""
pass
程序包运行程序的地方运行测试。并且当引发此预期异常时，sh会捕获该异常本身，然后重新引发自己的异常。我有办法检查我的原始异常是否以某种方式提出了吗？
例如，当我运行此代码时（预计此代码会引发该异常）：
sh我得到了这个异常：
sh.python3(
self.main_py_path,
self.live_cfg_path,
self.workflow_cfg_path)
好吧，我可以做类似的事情：
Traceback (most recent call last):
File "/home/oerp/src/devops-tools/tests/test_main.py", line 153, in test_full_workflow_1
self.workflow_cfg_path)
File "/usr/local/lib/python3.5/dist-packages/sh.py", line 1427, in __call__

STDOUT:

但是也许有更优雅的方法来检查我的异常？
