From 55bbc8ff4987d05b7d2f2d513caabd0a58fec021 Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Fri, 12 Oct 2018 23:54:13 +0200 Subject: [PATCH] selftests: pmtu: Allow selection of single tests As number of tests is growing, it's quite convenient to allow single tests to be run. Display usage when the script is run with any invalid argument, keep existing semantics when no arguments are passed so that automated runs won't break. Instead of just looping on the list of requested tests, if any, check first that they exist, and go through them in a nested loop to keep the existing way to display test descriptions.
