You should see 5 lines with "SUCCESS" below:
<script>
if (window.layoutTestController)
    layoutTestController.dumpAsText();

function checkExpected(actual, expected)
{
    if (actual != expected)
        document.writeln("<p>FAILURE: expected \"" + expected + "\", actual \"" + actual + "\"</p>");
    else
        document.writeln("<p>SUCCESS (value: \"" + actual + "\")</p>");
}

var metaTag = document.getElementById("test");
checkExpected(metaTag, "[object HTMLMetaElement]");
checkExpected(metaTag.name, "foo");
checkExpected(metaTag.scheme, "bar");
checkExpected(metaTag.httpEquiv, "content-type");
checkExpected(metaTag.content, "text/html; charset=UTF-8");
</script>
