In the following code, from "Secrets of the JavaScript Ninja," why does "Another test." show up in red font?
<html>
<head>
<title>Test Suite</title>
<script>
(function() {
var results;
this.assert = function assert(value, desc) {
var li = document.createElement("li");
li.className = value ? "pass" : "fail";
li.appendChild(document.createTextNode(desc));
results.appendChild(li);
if (!value) {
li.parentNode.parentNode.className = "fail";
}
return li;
};
this.test = function test(name, fn) {
results = document.getElementById("results");
results = assert(true, name).appendChild(
document.createElement("ul"));
fn();
};
})();
window.onload = function() {
test("A test.", function() {
assert(true, "First assertion completed");
assert(true, "Second assertion completed");
assert(true, "Third assertion completed");
});
test("Another test.", function() {
assert(true, "First test completed");
assert(false, "Second test failed");
assert(true, "Third assertion completed");
});
test("A third test.", function() {
assert(null, "fail");
assert(5, "pass")
});
};
</script>
<style>
#results li.pass { color: green; }
#results li.fail { color: red; }
</style>
</head>
<body>
<ul id="results"></ul>
</body>
</html>
