From 4e26f84abfbbfa88a66f8a3b7e5ea9e494d3caf3 Mon Sep 17 00:00:00 2001 From: Tomas Glozar Date: Thu, 26 Jun 2025 14:34:03 +0200 Subject: [PATCH] rtla/tests: Add tests for actions Add a bunch of tests covering most of both --on-threshold and --on-end. Parts sensitive to implementation of hist/top are tested for both.
