Unable to execute Selenium asynchronous script

Question

Why am I getting an exception with selenium 2.25.0 when trying to execute asynchronous script. ``` //navigate to my test page. String script = "var callback = arguments[arguments.length - 1];" + "getResult(callback)"; Object result = ((JavascriptExecutor)driver).executeAsyncScript(script, ""); System.out.println(result); ``` The test page contains the following script: ``` var result = true; function getResult(callback){ window.setTimeout(function(){callback(true);}, 3000); } ``` This throws an exception: ``` FAILED: testSeleniumAsync org.openqa.selenium.TimeoutException: Script execution failed. Script: var callback = arguments[arguments.length - 1];getResult(callback); Timed out waiting for asyncrhonous script result after 2 ms (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 11 milliseconds Build info: version: '2.25.0', revision: '17482', time: '2012-07-18 22:18:01' System info: os.name: 'Linux', os.arch: 'amd64', os.version: '3.2.0-27-…

Accepted Answer

Its very strange that the API is timing out in 2 ms.

I am guessing that the script time out is somehow incorrectly configured (<= 0sec). Since your window timeout occurs after 3 secs, try setting the script time out to some value greater than 3 secs, before you make the call.

Like so:

```
driver.manage().timeouts().setScriptTimeout(5, TimeUnit.SECONDS);
```

That might work.
