Nit: doctype.

Done.

You don't need an onload handler. Just put the script at the end of the page.

Done.

+  if (!window.testRunner)
+    return;
+
+  window.testRunner.dumpAsText();
+  drag();
+}
+
+
+function drag() {
+
+  var testElem = document.getElementById("text");
+  testElem.addEventListener("mousemove", function(event) {
+      event.preventDefault();
+  }, false);
+
+  var text_x = testElem.offsetLeft;
+  var text_y = testElem.offsetTop;
+
+  eventSender.mouseMoveTo(text_x, text_y);
+  eventSender.mouseDown();
+
+  // Start the selection
+  eventSender.mouseMoveTo(text_x, text_y + 1);
+
+  // Create the selection
+  eventSender.mouseMoveTo(text_x + 10, text_y + 10);
+  eventSender.mouseUp();
+
+  var range = window.getSelection().getRangeAt(0);
+  var result = range.toString().length > 0 ? "SUCCESS" : "FAILED";

You should use js-test.js instead of rolling this logic yourself.

Done.

+  document.getElementById("result").innerHTML = result;
+
+  window.testRunner.notifyDone();

+<p>Test for <a href="https://code.google.com/p/chromium/issues/detail?id=346473">bug
+346473</a>: Text selection should happen even if mousemove event is cancelled,
+since there is no default action specified for mousemove event in the spec which
+is to be prevented on defaultPrevent.</p>

"defaultPrevent"

Also since this is easy to test manually, you should explain how.
