From 4468e4ff3cb79e95cf87c49582bec86e44a32cca Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sebastian=20G=C5=82=C4=85b?= Date: Fri, 11 Oct 2024 12:45:09 +0200 Subject: [PATCH] [nrf fromlist] tests: boards: nrf: coresight_stm: Add performance test for STM MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extend STM testing with verification whether STM benchmark results are below predefined thresholds. Set thresholds arbitrarily. Add tests that allow code coverage calculation.
