python - 出生日期测试失败

Question

我是 python-django 编码的初学者。目前我正处于https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/Testing的挑战部分。我的测试进展顺利，除了def test_form_date_of_death_initially_set_to_expected_date(self)。错误是AssertionError: datetime.date(1900, 1, 1) != datetime.date(2020, 6, 11)据我了解，1900,1,1 是函数完成检查后返回给我的日期。但问题是我不知道这个日期是怎么出来的。我检查了我的文件，但看不到任何将其设置为 1900、1、1 的代码。如果未设置，这是默认日期吗？如果它本质上是默认的，我怎么设置测试作者的死亡日期，它仍然出现在 1900、1、1。如果有人可以帮助我，请不胜感激。谢谢
