Not exactly the simplest command, compared to just "sudo /path/to/dpdk-test --no-huge -m512 -- debug_autotest" Using sudo -E is what I tend to prefer in this case. :-) > > > * Calling tests as an execute action when doing a git rebase > > I am pretty sure I used DPDK_TEST= in rebase execute actions in the past too. > This probably works too: > $ git rebase -i HEAD^ -x 'DPDK_TEST=debug_autotest > build/app/test/dpdk-test --no-huge -m 512' > > > > > > Yes, again in both cases, other workarounds are generally available (e.g. > > sudo -E, and exporting to environemtn before rebase), but also generally > > less convenient. > > You find it less convenient when you want to run multiple tests. > I don't have that use case but I don't mind taking it. > Can you simply adjust the commitlog, or propose a new wording I can > take when applying? > Would just replacing the first paragraph as below be suitable? Since it's only a single sentence, the second paragraph can also be merged straight in with it to leave a 1-paragraph commit log message. "While having the ability to run a test based off the DPDK_TEST environment variable is useful, it's sometimes more convenient to specify the test name as a commandline parameter to a test binary." /Bruce
