### Troubleshooting
When running on Jenkins, watch out for the [ProcessTreeKiller](https://wiki.jenkins.io/display/JENKINS/ProcessTreeKiller) when running multiple parallel test jobs on the same machine. If you are spawning simulators in one test job, Jenkins might kill all your simulators when the first test ends - causing errors in the remaining test jobs!
Use `BUILD_ID=dontKillMe` to prevent this from happening.
