With the current implementation, meson handles which tests to run, and the command line. This gives us a clean interface from which to run tests. Note that the following command will run the tests requested: $ meson test ring_autotest ring_perf_autotest acl_autotest Meson itself supports two methods of launching tests from the same binary: argv and env variables. In this implementation, the DPDK_TEST env is set by the test runner - and the user doesn't have to use it manually at all, and it is not exported in the shell after the tests have run. In short - I don't see added value in reworking this to argc argv, or in using terminal tricks like echo "test" | sudo ./test. Actually, the current method has an easter egg included: If a developer is focused on a single test-case (TDD anyone? :), then they could use the DPDK_TEST env var as a feature, $ export DPDK_TEST=ring_autotest and run that test automatically when the binary is launched.
