Linux Kernel Testing Results by Linaro Feb 7th Edition
Tom Gall
This report is broken up into two parts, OpenEmbedded and Android. These are the two operating systems we are using to run a battery of tests in order to find regressions in the kernel as new patches are added.
The general list of tests that Linaro runs can be found at https://lkft.linaro.org/tests/
When we look for regressions tests often fall into 3 categories of results. Pass, Fail (a regression, exactly what we want to find) and Known Failure where there is a past history with the testcase. Often known failures are flaky testscases that need to be fixed.
