用法:
test.support.threading_helper.catch_threading_exception()
上下文管理器使用
threading.excepthook()
捕獲threading.Thread
異常。捕獲異常時設置的屬性:
exc_type
exc_value
exc_traceback
thread
請參閱
threading.excepthook()
文檔。這些屬性在上下文管理器出口處被刪除。
用法:
with threading_helper.catch_threading_exception() as cm: # code spawning a thread which raises an exception ... # check the thread exception, use cm attributes: # exc_type, exc_value, exc_traceback, thread ... # exc_type, exc_value, exc_traceback, thread attributes of cm no longer # exists at this point # (to avoid reference cycles)
