CircleCI Jest tests keep failing

Build Environment Running Tests
1

My Jest tests run locally, without any problems whatsoever. I can see them fail, and pass. However when i run my tests, through the CircleCI CI/CD pipeline, they always fail. I can install dependencies and run builds, without issue. The only test that fails to do anything is the one, for running my unit tests. My project is on GitHub.

Console error

#!/bin/bash -eo pipefail

npm info it worked if it ends with ok

I figured it out. FYI for anyone else who has this problem. It was the version of node i was using, node:4.8.2. Once i updated it to node:current the test script worked. So just make sure that you are running an up to date, stable release of node. https://circleci.com/docs/2.0/circleci-images/#nodejs
