handy little Selenium helper method to wait for a condition from the server side

WaitForCondition.cs

/*
Usage:

WaitForCondition(
() => _selenium.GetAttribute(string.Format("//div[@id='{0}']@style", divIdToWatch)).IndexOf("block") >= 0,
5000);

*/

private static void WaitForCondition(Func<bool> condition, int timeoutInMilliseconds)
{
    const int wait = 500;

    var attempts = timeoutInMilliseconds / wait;
    for (var attempt = 0; attempt < attempts; attempt++)
    {
        if (condition())
            break;
        Thread.Sleep(wait);
    }
}
