From 3e707b07f582c12ed78fa5516a97bf701bf0634c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micka=C3=ABl=20Sala=C3=BCn?= Date: Thu, 12 Dec 2024 18:42:21 +0100 Subject: [PATCH] selftests: ktap_helpers: Fix uninitialized variable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit __ktap_test() may be called without the optional third argument which is an issue for scripts using `set -u` to detect uninitialized variables and potential bugs. Fix this optional "directive" argument by either using the third argument or an empty string. This is required for the next commit to properly test script execution control.
