I just want to be able to execute: > make fast-check for fast checks (you decide what are and what are not) > make slow-check for slow checks, non overlapping, meaning that if you want to runa ll the checks, you'll have to use fast and then slow. The idea is to generalize the interface we use for the tests between all the ovirt projects so from ci we don't have to go keeping specific scripts for each provect and for each project version. And be able to run the fast checks (on each patchset, merges included) and the slow ones (on each merge only) separated so we can give feedback faster and not start the slow ones. Then after that goes the building of the rpm, and then the functional tests. And last the release if relevant. On patch: fast_check On merge: fast_check -> slow_check -> build -> functional_check -> release That flow is generic for all the projects, so each project will have to implement the same interface to run each step (I don't really care if it's make fast-check or just a bash script that runs whatever you need underneath, the key is not having to specify any options if possible and running just one line, the same everywhere). That simplifies a LOT the maintenance of the jenkins jobs, and allows to change the way checks are run bound to the version of the product. Next step is to specify the required dependencies inside the project, so the dependencies for the tests are also stored in the repo and bound to the code, and installed in the test env on demand so no more issues with versioning or new dependencies. Right now that is hardcoded in the job itself, making it break if any future version needs a different dependency list. Not sure yet what's the best way to do that though, maybe a simple puppet manifest would be the way to go... because having a requirements.txt file is python specific and not all the projects we have are python or use distutils at all.
