From e3350ba4a5b7573d4e14ee1dff8c414646435a04 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 4 Mar 2024 15:36:20 -0800 Subject: [PATCH] selftests: avoid using SKIP(exit()) in harness fixure setup selftest harness uses various exit codes to signal test results. Avoid calling exit() directly, otherwise tests may get broken by harness refactoring (like the commit under Fixes). SKIP() will instruct the harness that the test shouldn't run, it used to not be the case, but that has been fixed. So just return, no need to exit. Note that for hmm-tests this actually changes the result from pass to skip. Which seems fair, the test is skipped, after all.
