It would be nice if this light infrastructure were shared with all tests. I am
not sure how to do it, though.

+  completed = true;
+  // a bit of a hack just to try to get the script to stop running at this point
+  throw "completed";
+}
+
+function fail(message) {
+  if (completed) throw "completed";
+
+  console.log("FAIL: " + message);
+  chrome.test.fail(message);
+  complete();
+}
+
+function succeed() {
+  if (completed) throw "completed";
+
+  chrome.test.pass();
+  complete();
+}
+
+window.onerror = function(message, url, code) {
+  if (completed) return;
+
+  fail(message);
+};
+
+function expectTrue(test, message) {
+  if (!test) {
+    fail(message);
+  }
+}
+
+var expected = [
+  {"children": [
+    {"children": [], "id": "1", "parentId": "0", "title":"Bookmarks bar"},
+    {"children": [], "id": "2", "parentId": "0", "title":"Other bookmarks"}
+    ],
+   "id": "0", "title": ""
+  }
+];
+
+function compareTrees(left, right) {
+  console.log("compare");
+  console.log(JSON.stringify(right));
+  console.log(JSON.stringify(left));
+  // TODO(erikkay): do some comparison of dateAdded
+  if (left == null && right == null) {
+    console.log("both left and right are NULL");
+    return true;
+  }
+  if (left == null || right == null)
+    return false;
+  if (left.length < right.length)
+    return false;
+  for (var i = 0; i < left.length; i++) {
+    if (left[i].id != right[i].id)
+      return false;
+    console.log(left[i].title + " ? " + right[i].title);
+    if (left[i].title != right[i].title)
+      return false;
+    if (!compareTrees(left[i].children, right[i].children))
+      return false;
+  }
+  return true;
+}
+
+chrome.bookmarks.getTree(function(results) {
+  expectTrue(compareTrees(results, expected),
+             "getTree() result doesn't match expected");
+  expected = results;
