如何在覆盖 CRA Jest 配置时消除“运行所有测试的意外无效模式”警告？

Question

yarn test每当我在基于create-react-app 的React 应用程序中使用时，我都会在测试运行之前遇到长时间无效的测试模式警告。这些测试运行良好，但那个尴尬的警告并不那么方便。我有两个担忧：

• 我的配置中是否缺少某些内容导致出现这种情况？
• 有没有办法消除警告？

您的使用--具体是说它后面的所有内容实际上都是文件模式。So--config=jest.config.ts根本不被解释为一个选项，而令人困惑的错误是由于react-scripts test命令试图将其理解为文件模式而产生的。选项必须先于--
