Pull request overview

Ensures the sys_vars test session_track_system_variables_basic.test is skipped when the ha_example (EXAMPLE) plugin is not built/available, preventing failures in configurations where $HA_EXAMPLE_SO is unset.

Changes:

• Add --source include/have_example_plugin.inc to gate the test on availability of the EXAMPLE plugin.
