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

I'm using Jest to unit test my Sails JS application.

When the tests pass and finish, I'm getting this error:

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.

I set Jest timeout to 10000.

I also tried using Jest fake timers.

I've done the research before posting this question, but haven't found a good solution.

CodePudding user response：

I think my case is specific to how sails work, but I'll add the fix for reference:

NODE_ENV=test jest --runInBand
