Simple configuration of Jest with ts-jest produces error "ReferenceError: describe is not defined" in runtime. Here minimal example: https://github.com/PFight/jest-ts-describe-not-defined-problem
What I configured wrong?

Wired answer but may help someone. but in my case @types
, tsconfig
, and everything was ok and I still have the error, by the end, I figured that spec
and test
are in exclude
array in tsconfig
removed it and the error is gone.

I had the same problem but I needed the testEnvironment to be node. The solution is to downgrade to "jest": "^24.9.0"
. It seems like there's a problem with the latest version when testEnvironment is set to node.
UPDATE
It looks like this issue has been fixed in jest 25.2.2 per this comment https://github.com/facebook/jest/issues/9538#issuecomment-604522345 I haven't tested it though.

I had same problem in node v10.14.1.
Just update node to v10.16.2 and error was fixed.

Or you can add the type definitions for jest like this in your tsconfig:
"include": ["node_modules/@types", "test/**/**.ts"],
And add the types via installing it with npm -i @types/jest
I can't push to your repo though creating a PR is not possible..

Found the problem. It was next row in jest.config.js:
testEnvironment: 'node',
Just removed it and error was fixed.
