From be6ef728fd36049ea3822a54909a995bdecf6dd0 Mon Sep 17 00:00:00 2001 From: "Hongzhi.Song" Date: Fri, 29 Jun 2018 02:16:20 -0400 Subject: oeqa/runtime: Add testcases for kernel sample We are going to let runtime test support kernel tests. Now we just add kernel self-contained sample tests. And we plan to add overall kernel tests in the future. This patch is just add kernel samples test which contains about 13 tests enabled by kernel-sample.scc. So it needs statement, KERNEL_FEATURES_append += " features/kernel-sample/kernel-sample.scc" in local.conf.
