    <para>
      To test the results, issue:
      <command>dbus-run-session ninja test</command>. The tests
      require an active X session to run correctly. It is not necessary to
      run a  separate D-bus session if not in a GNOME session, but it
      provides a clean environment in any case. One test,
      <filename>native-headless</filename>, is known to fail.
    </para>
    -->
    <para>
      The test suite requires debug functions enabled in the build, and
      an external program called <command>xvfb-run</command>.
      If you wish to run the tests, you should
      download and install it before running <command>meson</command>.
      You can obtain it from
      <ulink url="&sources-anduin-http;/mutter/xvfb-run">xvfb-run</ulink>, and
      install it in <filename class="directory">/usr/bin</filename>.
      <command>xvfb-run</command> needs <command>Xvfb</command> at runtime,
      and <command>Xvfb</command> can be installed from either
      <xref linkend='xorg-server'/> or <xref linkend='xwayland'/>.
      You should also replace the
      <parameter>--buildtype=release -Dtests=false</parameter> in
      the <command>meson</command> command, with
      <parameter>--buildtype=debugoptimized -Dtests=true</parameter>.
      The test suite requires the mutter schema to be installed on the
      system, so it is better to run the tests after installing the package.
