UI User Testing for a Website - Selenium

here's a way to get Selenium to wait while the 'ajaxLoadingIcon' is showing:

private void waitOnAjaxLoading(ISelenium selenium)

{

for (int second = 0; ; second++)

{

if (second >= 60) Assert.Fail("timeout");

try

{

if (!selenium.IsElementPresent("BusyDiv_undefined")) break;

}

catch (Exception)

{ }

Thread.Sleep(1000);

}

}
