python - 我写了一个 LockedList 装饰器。我该如何测试它？

Question

from threading import Lock
from threading import Thread

class LockedList(list):
    def __init__(self, *args, **kwargs):
        self._lock = Lock()
        super(LockedList, self).__init__(*args, **kwargs)

    def remove(self, elem):
        with self._lock:
            super(LockedList, self).remove(elem)

    def insert(self, i, elem):
        with self._lock:
            super(LockedList, self).insert(i, elem)

    def __contains__(self, elem):
        with self._lock:
            super(LockedList, self).__contains__(elem)


list = [2, 3, 4]
for i in range(100):
    t1 = threading.Thread(target=list.insert(i, i))
    if i % 2 == 0:
        t2 = threading.Thread(target=list.remove(i))

#10 output
for i in range(len(list)):
    if i % 10 == 0 and i != 0:
        print()
    print(list[i], end=' ')

我为使用locked_list 装饰器编写了这段代码。但我不知道如何测试它。测试代码是否正确？我想通过使用线程来测试 list.insert() 和 list.remove() 是否会导致竞争条件。
