From 9da74836740d9c753fb6cd270f7c75c5258836de Mon Sep 17 00:00:00 2001 From: "Matthieu Baerts (NGI0)" Date: Fri, 23 Feb 2024 21:17:53 +0100 Subject: [PATCH] selftests: mptcp: lib: catch duplicated subtest entries It is important to have a unique (sub)test name in TAP, because some CI environments drop tests with duplicated name. When adding a new subtest entry, an error message is printed in case of duplicated entries. If there were duplicated entries and if all features were expected to work, the script exits with an error at the end, after having printed all subtests in the TAP format. Thanks to that, the MPTCP CI will catch such issues early.
