laforge gerrit-no-reply at lists.osmocom.orglaforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bsc/+/21973 ) Change subject: handover_test: add test_congestion_favor_best_target_rxlev.ho_vty ...................................................................... handover_test: add test_congestion_favor_best_target_rxlev.ho_vty The aim is to pin the current basic behavior of handover decision 2, before modifying the algorithm conditions to fix some bugs in upcoming patches -- so far no test ensures this particular detail.
