JEST tests complete successfully but returns exit status 1

[muthukrishnanm]

I run JEST tests using npm run test:jest and the corresponding entry in package.json is

"test:jest": "jest --config=./jest.config.js",

All tests run successfully, but returns with exit code 1

I am not sure why the process exits with status code 1 even though all tests pass.

Repro please, or it didn't happen

Hi @thymikee

This happens in our repo and I am not able to create a reproducible sample repo. But what I could say is that the following command runs successfully,

node /workspace/vc/vco/src/server/node/node_modules/.bin/jest --config=./jest.config.js

whereas when running JEST cases via npm is failing.

$ npm run test:jest

Can you try with yarn as well then? Maybe it's an issue with npm itself, try upgrading Node

[muthukrishnanm]

I did a little more debugging and I could see that the exit code of the JEST execution (even when not run in npm context) is 1.

$node /workspace/vc/vco/src/server/node/node_modules/.bin/jest --config=./jest.config.js

<Runs all the tests successfully >

$ echo $?
1

[thymikee]

Anyway, without a repro there's nothing I can do. Please make sure you're on the latest version and try to come up with a minimal case by filtering out some tests until you get a correct exit code.

I'm running into same issue, test passess successfully but jest returns status code 1 and npm errors.

PASS  src/test/restart.test.ts
  √ restart (3438ms)

Not sure if it's related but I'm using TypeScript and doing a async test with child processes and this seems so far to be the only case where I've encountered such behaviour. Though there seems to be no difference whether I'm running with ts-jest transform or directly against built js files. Oh and everything is updated to latest versions.

[mikkotikkanen]

As an update to this, it also seems to fail with Yarn

 PASS  src/test/restart.test.ts

error Command failed with exit code 1.

Same thing happens to me as for OP, if I run Jest directly from node_modules/.bin/jest it run through successfully but when ran as npm script it returns exit code 1. Happens with both v24.x and v25.x.

Same issue here, any solutions?

Edit: Upgrading node to latest version solved the issue for me

Getting the same here pretty frequently when running in CI. It is intermittent but frequent enough to have started slowing things down.

Did you guys find a solution?

I'm seeing the same issue and now CI is failing all buddy builds.

Also getting this on our CI (Codeship):

Here's the command being run:

jest --no-cache "--maxWorkers=1"

Jest 25.2.7

We are upgrading from React Native 59 to 61 which has brought a new Jest version with it.

I'm going to try downgrading back to Jest 24 and see if tests pass again.

[alexisponcet]

Same problem with yarn only v1.21.1 (jest v.25.2.3)
