From 6a954ce5834c8026adecff8478c3d827640bc647 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Sun, 4 Apr 2021 11:33:14 +0100 Subject: oeqa/concurrencytest: Fix display of test stdout/stderr If oe-selftest is run with -j, the output to stdout/stderr is being lost at present. Capture this and display it upon test failure. We have code that previously tried to enable this but it wasn't functioning correctly. This should give more usable error reports on the autobuilder. This code will mix stdout and stderr as the output is streamed from the test server without markup. This is most in keeping with subunit/testools though and the easiest way to handle the various challenges here as far as I can see.
