Question

In the code below, I attempt to wait until an element is visible:

var wait = new WebDriverWait(Driver.Instance, TimeSpan.FromSeconds(10));
wait.Until(ExpectedCon         


        

Answer 1

public void WaitForElementNotVisible(string id, int seconds)
    {

        try
        {
            var wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver, TimeSpan.FromSeconds(seconds));                   
            wait.Until(driver1 => !visibility(id));
            Console.WriteLine("Element is not visible..");
        }
        catch (WebDriverTimeoutException)
        {
            Assert.Fail("Element is still visible..");
        }


    }


    bool visibility(string id)
    {
        bool flag;
        try
        {
            flag = driver.FindElement(By.Id(locator)).Displayed;
        }
        catch (NoSuchElementException)
        {
            flag = false;
        }
        return flag;
    }
