Jest: ReferenceError: You are trying to `import` a file after the Jest environment has been torn down

Question

我正在使用 Jest 对我的 Sails JS 应用程序进行单元测试。

测试通过并完成后，出现此错误：

Ran all test suites.

ReferenceError: You are trying to `import` a file after the Jest environment has been torn down. From test/controllers/foo/bar.test.js.

                                               ^

我将 Jest 超时设置为 10000。

我也试过使用 Jest 假计时器。

我在发这个问题之前做了研究，但是没有找到好的解决方案。

Answer 1

我认为我的案例是针对帆的工作原理的，但我会添加修复以供参考：

NODE_ENV=test jest --runInBand

参考：https://jestjs.io/docs/cli#--runinband
