Example How To Handle Page Synchronization and Loading In Angular JS Site using Webdriver


This method helps you to wait till Progress bar still on page.

public void HoldTillPageSynchronizationCompletes()
        {
            bool isPageInProgress = HoldTillElementIsVisible(By.CssSelector("div[class=Progress]"), 5);
            if (isPageInProgress)
            {
                var stopWatch = new Stopwatch();
                stopWatch.Start();
                while (stopWatch.Elapsed.TotalMinutes < _waitTimeOut)
                {
                    string isPageStillInProgress = WebDriver.FindElement(By.CssSelector("table[id=mydivimg]")).GetAttribute("style");
                    if (isPageStillInProgress.Contains("display: none;"))
                    {
                        stopWatch.Stop(); break;
                    }
                }
            }
        }


This method helps you to wait till search records visible on page.

public void HoldTillRecordLoadInPageCompletes()
        {
            bool isLoadRecordInProgress = HoldTillElementIsVisible(By.CssSelector("div[style=display: block;]"), 5);
            if (isLoadRecordInProgress)
            {
                var stopWatch = new Stopwatch();
                stopWatch.Start();
                while (stopWatch.Elapsed.TotalMinutes < _waitTimeOut)
                {
                    string isLoadRecordStillInProgress = WebDriver.FindElement(By.CssSelector("div[id=load_Summary]")).GetAttribute("style");
                    if (isLoadRecordStillInProgress.Contains("display: none;"))
                    {
                        stopWatch.Stop(); break;
                    }
                }
            }
        }

This is a common method helps you to hold for finding the element. In this element surely visible on the page but after sometime.

protected bool HoldTillElementIsVisible(By by, int timeOut = -1)
        {
            //Wait For Element
            if (timeOut == -1)
            {
                timeOut = this._waitTimeOut;
            }
            try
            {
                WebDriverWait wait = new WebDriverWait(WebDriver, TimeSpan.FromSeconds(timeOut));
                wait.Until(ExpectedConditions.ElementIsVisible(@by));
                return true;
            }
            //Exception Handling
            catch (Exception)
            {
                return false;
            }
        }
