          In regular circumstances you shouldn't use this interface, since you not
          only override default log level, but also the one supplied at test execution
          time. Prefer to use runtime parameters <a class="link" href="../../utf_reference/rt_param_reference/log_level.html" title="log_level"><code class="computeroutput"><span class="special">--</span><span class="identifier">log_level</span></code></a>
