[pve-devel] [PATCH ha-manager v3 12/15] test: add test cases for rules config

Fri Jul 4 20:16:52 CEST 2025
Add test cases to verify that the rule checkers correctly identify and
remove HA rules from the rules to make the rule set feasible. For now,
there only are HA Node Affinity rules, which verify:
- Node Affinity rules retrieve the correct optional default values
- Node Affinity rules, which specify the same HA resource more than
once, are dropped from the rule set
