<title>Project Testing and Release Process</title>
<section id='test-daily-devel'>
<title>Day to Day Development</title>
<para>This section details how the project tests changes, through automation on the
Autobuilder or with the assistance of QA teams, through to making releases.</para>
<para>The project aims to test changes against our test matrix before those changes are
merged into the master branch. As such, changes are queued up in batches either in the
<filename>master-next</filename> branch in the main trees, or in user trees such as
<filename>ross/mut</filename> in <filename>poky-contrib</filename> (Ross Burton
helps review and test patches and this is his testing tree).</para>
<para>We have two broad categories of test builds, including "full" and "quick". On the
Autobuilder, these can be seen as "a-quick" and "a-full", simply for ease of sorting in
the UI. Use our Autobuilder console view to see where me manage most test-related items,
available at: <link linkend=""
>https://autobuilder.yoctoproject.org/typhoon/#/console</link>.</para>
<para>Builds are triggered manually when the test branches are ready. The builds are
monitored by the SWAT team. For additional information, see <link linkend=""
>https://wiki.yoctoproject.org/wiki/Yocto_Build_Failure_Swat_Team</link>. If
successful, the changes would usually be merged to the <filename>master</filename>
branch. If not successful, someone would respond to the changes on the mailing list
explaining that there was a failure in testing. The choice of quick or full would depend
on the type of changes and the speed with which the result was required.</para>
<para>The Autobuilder does build the <filename>master</filename> branch once daily for
several reasons, in particular, to ensure the current <filename>master</filename> branch
does build, but also to keep <filename>yocto-testresults</filename> (<link linkend=""
>http://git.yoctoproject.org/cgit.cgi/yocto-testresults/</link>), buildhistory
(<link linkend="">http://git.yoctoproject.org/cgit.cgi/poky-buildhistory/</link>),
and our sstate up to date. On the weekend, there is a master-next build instead to
ensure the test results are updated for the less frequently run targets.</para>
<para>Performance builds (buildperf-* targets in the console) are triggered separately every
six hours and automatically push their results to the buildstats repository at: <link
linkend="">http://git.yoctoproject.org/cgit.cgi/yocto-buildstats/</link>. </para>
<para>The 'quick' targets have been selected to be the ones which catch the most failures or
give the most valuable data. We run 'fast' ptests in this case for example but not the
ones which take a long time. The quick target doesn't include *-lsb builds for all
architectures, some world builds and doesn't trigger performance tests or ltp testing.
The full build includes all these things and is slower but more comprehensive.</para>

<section id='test-yocto-project-autobuilder-overview'>
<title>Release Builds</title>
<para>The project typically has two major releases a year with a six month cadence in April
and October. Between these there would be a number of milestone releases (usually four)
with the final one being stablization only along with point releases of our stable
branches.</para>
<para>The build and release process for these project releases is similar to that in <link
linkend="test-daily-devel">Day to Day Development</link>, in that the a-full target
of the Autobuilder is used but in addition the form is configured to generate and
publish artefacts and the milestone number, version, release candidate number and other
information is entered. The box to "generate an email to QA"is also checked.</para>
<para>When the build completes, an email is sent out using the send-qa-email script in the
<filename>yocto-autobuilder-helper</filename> repository to the list of people
configured for that release. Release builds are placed into a directory in <link
linkend="">https://autobuilder.yocto.io/pub/releases</link> on the Autobuilder which
is included in the email. The process from here is more manual and control is
effectively passed to release engineering. The next steps include:<itemizedlist>
<listitem>
<para>QA teams respond to the email saying which tests they plan to run and when
the results will be available.</para>
</listitem>
<listitem>
<para>QA teams run their tests and share their results in the yocto-
testresults-contrib repository, along with a summary of their findings.
</para>
</listitem>
<listitem>
<para>Release engineering prepare the release as per their process. </para>
</listitem>
<listitem>
<para>Test results from the QA teams are included into the release in separate
directories and also uploaded to the yocto-testresults repository alongside
the other test results for the given revision.</para>
</listitem>
<listitem>
<para>The QA report in the final release is regenerated using resulttool to
include the new test results and the test summaries from the teams (as
headers to the generated report).</para>
</listitem>
<listitem>
<para>The release is checked against the release checklist and release readiness
criteria.</para>
</listitem>
<listitem>
<para>A final decision on whether to release is made by the YP TSC who have
final oversight on release readiness.</para>
