我们从Python开源项目中，提取了以下15个代码示例，用于说明如何使用doctest.UnexpectedException()。
def _check_docs(self, module): if self._skip: # Printing this directly to __stdout__ so that it doesn't get # captured by nose. print("Warning: Skipping doctests for %s because " "pdbpp is installed." % module.__name__, file=sys.__stdout__) return try: doctest.testmod( module, verbose=True, raise_on_error=True, optionflags=self.flags, ) except doctest.UnexpectedException as e: raise e.exc_info[1] except doctest.DocTestFailure as e: print("Got:") print(e.got) raise
