I am having some problems getting my concourse jobs to execute sequentially. The reason I am trying to do this is because our current set up results in all jobs being executed immediately. This overwhelms our testing resources and causes false failures. I have tried every permutation that I can think of around serial: true and none of it has worked. Attached in a picture of the pipeline in question.
What I would like is anytime the tests are executed, either manually via the start-pipeline job or the twice per day timer, that jobs 1, 2, 3, and 4 are executed sequentially (or in pairs). Is this something that can be done easily?
