I am using the lock() in my company. The helper-plugin finds a port but two jobs on one machine are so predicable that this mechanism would not be reliable. It happened to me in my company. The helper may help but it does not guarantee anything.
There are tests which work but they are not much reliable if e.g. the machine is overloaded by neighboring job on the same machine. For instance ParallelComputerBuilderTest computes exec time of parallel test which can be perfectly computed. The delays are 0.5 second and they should be longer. It's obvious why. The next is the Integration Test 1295 which has some race condition. See another e-mail in our mailing list. I am discussing it already with the person who created the IT and the native library too. It does not make sense to have parallel CI jobs unless I will improve these tests. The point is first to understand the internals of the project from the history and the other things will come by themselves. After the improvements are made the parallel execution can be used and the likelihood that one test breaks due to concurrency is lower. Notice we have 1400 tests altogether and 21 Jenkins jobs and none of the tests must fail. We should make a deal. We should not directly commit to the master unless we make a code review together in a particular branch. The branch should be open with name e.g. SUREFIRE-12345 which would be the name of Jira issue. I use to have one commit per branch (wasn't last time I know) and I use *git --amend* till it's acceptable. The commit has name "[SUREFIRE-12345] Title in JIRA". It's too late. Let's talk tomorrow evening. Cheers Tibor On Sun, Feb 18, 2018 at 11:26 PM, Olivier Lamy <ol...@apache.org> wrote: > what is the issue with helper-plugin?
