Jest has detected the following 1 open handle potentially keeping Jest from exiting: TCPSERVERWRAP

I still haven’t found a perfect solution, but for the moment I went for this workaround :

jest --config ./test/jest-e2e.json --forceExit

The –forceExit option kill the openHandles somehow and unlock everything.
Yet, I’m still looking for the “proper way” of handling that issue.
