The <span class="emphasis"><em>Unit Test Framework</em></span> provides the decorator <a class="link" href="../utf_reference/testing_tool_ref/decorator_timeout.html" title="timeout (decorator)"><code class="computeroutput"><span class="identifier">timeout</span></code></a> that specifies a time-out
for a specific <span class="bold"><strong>test case</strong></span>, The argument time
(in seconds) sets the maximum allowed duration of a test case. If this time
is exceeded the test case is forced to stop and is reported as failure.
