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删除一个测试，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？我和jest有一个类似的问题： 在我不断地向“XXXX.test.js”文件添加更多测试之后，在某个时候，除了一些测试之外，它失败了，错误是“无法创建属性”\u调用了数字“10”。因此，我尝试增加超时时间，但没有帮助

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

我想我们都在尝试做同样的事情（Udemy）：

将这段代码放在每个测试文件的顶部 
Number.prototype.\u called={}；

我更改了安装文件中的jest
超时设置，它对我有效：

将这一行添加到
setup.js
中，用于jest:


jest.setTimeout（30000）；

更改超时解决了部分问题：）


在每个测试文件的顶部添加“Number.prototype._called={}；”对我来说很有用。重构这行代码的一种方法是将其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。
这很有效！谢谢
