与 Jest 一起使用时 Firebase 模拟器发生泄漏

Question

我正在使用 firebase 模拟器来运行我的笑话测试：

\n

包.json：

\n

{\n"scripts": {\n    "test": "firebase emulators:exec --only firestore --project sample jest",\n  },\n}\n

\n

笑话.config.json：

\n

{\n  "preset": "ts-jest",\n  "testEnvironment": "node",\n  "modulePathIgnorePatterns": ["<rootDir>/lib/"]\n}\n

\n

当我运行时，我收到以下消息

\n

\n

工作进程未能正常退出，已被强制退出。这可能是由于拆卸不当导致测试泄漏造成的。尝试使用 --detectOpenHandles 运行来查找泄漏。

运行时--detectOpenHandles我什么也没看到

正常吗？

Answer 1

您可以通过按顺序而不是并行运行所有测试来解决此问题。

所以代替这个：

jest --watch

尝试这个：

jest --watch --runInBand
