<p>This method can be safely called at any time, including between or outside tests. It is designed for use by plugins and integration layers.</p>

<p>In general, you should not use this method and instead throw an error. QUnit automatically finds and reports uncaught errors. The following are handled by default and should not be connected to <code class="language-plaintext highlighter-rouge">QUnit.onUncaughtException()</code> a second time:</p>
