Change The Download Path For IE using C# !

We can change the download path in IE which helps to verify the download file using Webdriver in IE.

RegistryKey rKey = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Internet Explorer\Main", true);

            if (rKey != null)

              rKey.SetValue("Default Download Directory", @"E:\E$", RegistryValueKind.String);

For disabling Download Prompt, we can use ESC key by Selenium or change IE settings using RegEdit.

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;
            }
        }

Create Logging In Webdriver !

private static IWebDriver IEWebDriver()

        {

            //Get The Machine Processor Architecture

            String getProcessorArchitecture = Microsoft.Win32.Registry.GetValue(

                "HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\Session Manager\\Environment"

                , "PROCESSOR_ARCHITECTURE", null).ToString();

            //Get IE Driver Path

            String getIeDriverPath =

                (Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase)

                + "\\..\\..\\..\\..\\ExternalAssemblies\\" + ((getProcessorArchitecture == "x86") ? "x86" : "x64")).Replace("file:\\", "");

            //Start Internet Explorer Driver Service

            InternetExplorerDriverService ieservice = InternetExplorerDriverService.CreateDefaultService(getIeDriverPath);

            ieservice.LoggingLevel = InternetExplorerDriverLogLevel.Trace;

            //Get Log Execution Path

            String getExecutingPath = new FileInfo(Assembly.GetExecutingAssembly().Location).DirectoryName;

            ieservice.LogFile = Path.Combine(getExecutingPath, "Log", "IEDriver" + DateTime.Now.Ticks + ".log");

            //Set Internet Explorer Options

            InternetExplorerOptions options = new InternetExplorerOptions

                                                  {

                                                      IntroduceInstabilityByIgnoringProtectedModeSettings = true,

                                                      UnexpectedAlertBehavior = InternetExplorerUnexpectedAlertBehavior.Ignore,

                                                      IgnoreZoomLevel = true,

                                                      EnableNativeEvents = true,

                                                      RequireWindowFocus = true,

                                                  };

            //Create Internet Explorer Driver Object

            IWebDriver webDriver = new InternetExplorerDriver(ieservice, options, TimeSpan.FromMinutes(20));

            //Set WebDriver Page Load Time

            webDriver.Manage().Timeouts().SetPageLoadTimeout(TimeSpan.FromSeconds(timeOut));

            //Set The Cursor Position Center of the Screen

            Cursor.Position = new Point(Screen.PrimaryScreen.Bounds.Width / 2, Screen.PrimaryScreen.Bounds.Height / 2);

            return webDriver;

        }

Selenium : Scroll Automatically Before Click On Element

If you want to click() on a WebElement, but it is not showing because it is in invisible state. So, we need scroll the WebElement to make it in visible state and perform click() action.

((JavascriptExecutor) webDriver).executeScript "arguments[0].scrollIntoView(true);", webelementObject); 

Handle 'HTML text editor' in selenium RC and WebDriver

We could not directly insert text in the HTML editor. To automate the HTML editor we need to first click on the Show view source image button in the Editor tool box and then we can able to insert text in HTML editor text area.

WebDriver.FindElement(By.Id("viewsource")).Click();

WebDriver.FindElement(By.Id("txtHTMLEditor_textarea")).SendKeys("This is my Text!");

Webdriver Handling IEdriver.exe path of 32/64 bit machine !

Webdriver handling IEdriver.exe for 32 Bit and 64 bit machine. Now, we don’t need to bother to change every time the path for IEdriver.exe for 32/64 bit machine. Just add the below code and keep both IEdriver.exe file in a folder and it would automatically choose according to machine configuration.

String processorArchitecture = Microsoft.Win32.Registry.GetValue(

                "HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\Session Manager\\Environment"

                , "PROCESSOR_ARCHITECTURE", null).ToString();

            string ieDriverPath =

                (Path.GetDirectoryName(

                System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase)

                + "\\..\\..\\..\\..\\ExternalAssemblies\\" + ((processorArchitecture == "x86") ? "x86" : "x64")).Replace("file:\\", "");

Webdriver Ignoring UnexpectedAlertBehavior and Zoom Level

With 'UnexpectedAlertBehavior' option we can do any work in front like chatting while in background window scripts are executing and 'IgnoreZoomLevel ' we can also run scripts at any zoom level.

InternetExplorerOptions options = new InternetExplorerOptions

                                                  {

                                                      IntroduceInstabilityByIgnoringProtectedModeSettings = true,

                                                      UnexpectedAlertBehavior = InternetExplorerUnexpectedAlertBehavior.Ignore,

                                                      IgnoreZoomLevel = true                                                     

                                                  };

IWebDriver webDriver = new InternetExplorerDriver(ieDriverPath, options, TimeSpan.FromMinutes(10));            webDriver.Manage().Timeouts().SetPageLoadTimeout(TimeSpan.FromSeconds(timeOut));

return webDriver;
