<p>Test for <a href="https://bugs.webkit.org/show_bug.cgi?id=18837">Bug 18837: Database panel fails to display tables if any value is NULL</a>.</p>
<p>To test:</p>
<ol>
    <li>Open the Inspector</li>
    <li>Go to the Databases panel</li>
    <li>Click on the <code>DisplaySQLNull</code> table inside the <code>InspectorTest</code> database</li>
</ol>
<p>If the contents of the table appear (a single row with the value
"<code>null</code>" in the <code>test</code> column), you have passed the
test.</p>
