Raghavendra has been working on a patchset that does a better job of
segregating tests by module. I'll let him explain the specifics.
tests directory uses two different taxonomies today. One is by type of tests where you find bugs/ performance/ basic/ etc. The other of type of feature where you have features/ experimental/ bitrot/ georep/ etc. I am working on moving all into first category where we have
1. functional/ basic
2. regression
3. performance (example: measure time for kernel untar with and without patch)
4. integration (tests with samba/qemu/nfs-ganesha)
5. stress (ambitious for now, mentioned for completeness)
6. upgrade/update (we should not be breaking updates)
My vision in this regard is something like this:
* A patchset gets Verified +1.
* A meta job is kicked off which determines regression jobs to run.
If the patch only touches GFAPI, we kick off the GFAPI regression tests. If
it touches multiple modules, we kick off the tests for these specific
modules.
As explained in the other reply this is not that trivial. Most of the components do interact with each other and may break the functionality. It is only modules which provide alternate functionality like AFR, EC and JBR that can be tested exclusive manner.
* The results for each platform are aggregated under our current labels similar
to how we aggregate results of multiple tests into one label for smoke.
This is possible.
Am I being too ambitious here? Is there something I'm missing?
