I will keep investigating the possibilities of migrating everything to LF Jenkins. One difficulty we have is the "Jenkins Library" build which will fail on LF Jenkins due to the permission limitation we have. Will see what we can do. The tests for Jenkins Library code is suggested because if it fails, it may indicate every other builds using that branch will fail. The test has to be performed against a real Jenkins server, not a virtual JVM environment because Jenkins handles Groovy scripts differently. The way of testing Jenkins Library is it will try to create a job through Jenkins API and start the build and check result, which is against the permission scheme we have on LF Jenkins.
