Same here, although having distaf-libs-gluster in the man distaf framework might be good too. Many frameworks also provide plugins of some kind, I see the libs as something like a plugin. In the end, I do not really care very much. Just check with whoever is writing test-cases that need library extensions. Hopefully the library changes are rare (on future) and new test-cases do not need any framework/libs modifications. Once the libs are (more) stable, maybe move them to the main distaf repo. > > Library functions and test cases both go into a subdirectory inside > > glusterfs.git.

Gluster git has tests + distaf-libs-gluster ( We can even avoid > packaging these two for now.

This makes it much easier for writing and running test cases. All the tests that we do in the CentOS CI should only install RPMs, that makes it very simple to run the same tests on different environments. At the moment we package the tests/ directory for non-official builds already. We do not want to provide the glusterfs-regression-tests RPM in repositories for users where they can install the package and easily break their existing deployment. But installing the package on a test-machine with the matching binary RPMs makes testing pretty smooth.
