I have a Node CLI being tested with Travis. The tests all complete successfully however it seems that Jest hangs for eternity until Travis decides it has had enough and fails the build. The tests exit cleanly in debug mode and locally, and I have tried all manner of Jest options, e.g. reduce concurrency, attempt to identify open handles, but to no avail.
Latest build: https://travis-ci.com/wpk-cli/wpk/jobs/192792401
