I\'m working on a C# Selenium-WebDriver. After send key, I want to wait few seconds. I do the following code to wait for 2 seconds.

    I would avoid at all cost using something like that since it slows down tests, but I ran into a case where I didn't had other choices.

    public void Wait(double delay, double interval)
    {
        // Causes the WebDriver to wait for at least a fixed delay
        var now = DateTime.Now;
        var wait = new WebDriverWait(myWebDriver, TimeSpan.FromMilliseconds(delay));
        wait.PollingInterval = TimeSpan.FromMilliseconds(interval);
        wait.Until(wd=> (DateTime.Now - now) - TimeSpan.FromMilliseconds(delay) > TimeSpan.Zero);
    }
    

    It's always better to observe the DOM somehow, e.g.:

    public void Wait(Func condition, double delay)
    {
        var ignoredExceptions = new List() { typeof(StaleElementReferenceException) };
        var wait = new WebDriverWait(myWebDriver, TimeSpan.FromMilliseconds(delay)));
        wait.IgnoreExceptionTypes(ignoredExceptions.ToArray());
        wait.Until(condition);
    }
    
    public void SelectionIsDoneDisplayingThings()
    {
        Wait(driver => driver.FindElements(By.ClassName("selection")).All(x => x.Displayed), 250);
    }
