BR, Jani.</pre> </blockquote> The purpose of the <code>kms_feature_discovery</code> test is to verify that all necessary configurations are in place. If a DP 2.1 SST monitor is not connected in the CI environment, the test will be skipped, indicating that SST UHBR coverage is missing. Since DP 2.1 SST support is already provided by existing tests, this test simply confirms whether the appropriate monitor is available to enable that coverage.
