示例1: test_get_traced_memory
def test_get_traced_memory(self):
# Python allocates some internals objects, so the test must tolerate
# a small difference between the expected size and the real usage
max_error = 2048
# allocate one object

tracemalloc.clear_traces()
obj, obj_traceback = allocate_bytes(obj_size)
