有人能帮我吗？我尝试了很多解决方案，但没有一个对我有效：(
如果我从测试文件中的所有测试中选择一个测试，它可以正常工作如果我再次添加删除的测试，则会发生错误这个错误可能是因为时间问题而发生的吗
将这段代码放在每个测试文件的顶部Number.prototype._called = {};
我在设置文件中更改了jesttimeOut设置，它对我有效：
将此行添加到setup.js中以开玩笑：jest.setTimeout(30000);
更改超时解决了部分问题：(
添加"；Number.protype._called=｛｝"重构这行代码的一种方法是将它添加到测试目录中的setup.js文件中，而不是将其添加到每个测试文件中。
我对jest也有类似的问题：在我不断向'XXXX.test.js'文件添加更多测试后，在某个时候，除了一些测试之外，它会失败，并出现错误"无法在数字"10"上创建属性"_called"；。所以，我试着增加超时时间，但无济于事。
我的解决方案是：我制作了另一个测试文件"XXXX_part2.tests.js"，然后将所有新测试复制到该文件中并运行测试。这为我解决了问题。
我认为我们都在努力做同样的事情(Udemy(：
