Java – selenium asynchronous script cannot be executed

Why do I get selenium 2.25 when I try to execute an asynchronous script Exception for 0

//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 scripts:

var result = true;
function getResult(callback){
    window.setTimeout(function(){callback(true);},3000);
}

This raises 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)

If I remove setTimeout from my script and I call a callback, it works But that's not what I want

thank you.

Solution

It is very strange that the API timed out within 2 ms

I guess the script timeout is incorrectly configured in some way (< = 0sec) Since your window timeout occurs after 3 seconds, try setting the script timeout to a value greater than 3 seconds before making a call like this:

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

This may work
