I know there is a way in Selenium to launch a browser (at least in Chrome) and later attach to that instance. Can you do the same thing through Atata?
Here is the sample that starts Chrome and then attaches Atata (ChromeDriver instance) to the created Chrome.
// Set static or find available port number:
int chromePort = 9222;
// Run Chrome process:
Process chromeProcess = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = #"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe",
Arguments = $"https://demo.atata.io/ --new-window --remote-debugging-port={chromePort} --user-data-dir=C:\\Temp"
}
};
chromeProcess.Start();
// Create Atata context attached to the Chrome:
AtataContext.Configure()
.UseChrome()
.WithOptions(x => x.DebuggerAddress = $"127.0.0.1:{chromePort}")
.Build();
// Do some actions using Atata:
Go.To<OrdinaryPage>(url: "https://demo.atata.io/products")
.PageTitle.Should.Contain("Products");
// Clean up (just don't do it exactly like here. Use "using (...)", etc.):
AtataContext.Current.Dispose();
chromeProcess.CloseMainWindow();
chromeProcess.Dispose();
The main thing to attach to Chrome is .UseChrome().WithOptions(x => x.DebuggerAddress = $"127.0.0.1:{chromePort}").

The problem is that I need to get the PID of IE browser instances so that I can close the IE browser(Working in C#).
I launched the IE browser using Selenium and then used Driver Service class as :-
InternetExplorerDriverService driverdetails = InternetExplorerDriverService.CreateDefaultService();
Console.WriteLine(driverdetails.Port);
The plan is to get the port and then have its child process. I am able to do so using a debugger by entering the value of Port manually. But, the port fetched by driverdetails.Port was not the actual port used by my driver.
Is there any was, I can find the Port for any given driver service?
For IE i have an alternative to launch IE and get the URL with port which says http://localhost:. However, this is not the case with other browsers. My want is to make the generic code and hence I am using the Driver Service object.
As far as I know, the InternetExplorerDriverService's ProcessID property gets the process ID of the running driver service executable, and we can't get the IE browser instance PID through the InternetExplorer webdriver. If you want to get the PID, you could try to use the Process class.
From your description, it seems that you want to close the IE tab or window by using the IE Webdriver. If that is the case, I suggest you could use InternetExplorerDriver WindowHandles to get the opened windows, then use the switchto method to switch the window and check the url or title, finally, call the Close method to close the IE window. Please refer to the following sample code:
private const string URL = #"https://dillion132.github.io/login.html";
private const string IE_DRIVER_PATH = #"D:\Downloads\webdriver\IEDriverServer_x64_3.14.0"; // where the Selenium IE webdriver EXE is.
static void Main(string[] args)
{
InternetExplorerOptions opts2 = new InternetExplorerOptions() { InitialBrowserUrl = "https://www.bing.com", IntroduceInstabilityByIgnoringProtectedModeSettings = true, IgnoreZoomLevel = true };
using (var driver = new InternetExplorerDriver(IE_DRIVER_PATH, opts2))
{
driver.Navigate();
Thread.Sleep(5000);
//execute javascript script
var element = driver.FindElementById("sb_form_q");
var script = "document.getElementById('sb_form_q').value = 'webdriver'; console.log('webdriver')";
IJavaScriptExecutor jse = (IJavaScriptExecutor)driver;
jse.ExecuteScript(script, element);
InternetExplorerDriverService driverdetails = InternetExplorerDriverService.CreateDefaultService(IE_DRIVER_PATH);
Console.WriteLine(driverdetails.Port);
// open multiple IE windows using webdriver.
string url = "https://www.google.com/";
string javaScript = "window.open('" + url + "','_blank');";
IJavaScriptExecutor jsExecutor = (IJavaScriptExecutor)driver;
jsExecutor.ExecuteScript(javaScript);
Thread.Sleep(5000);
//get all opened windows (by using IE Webdriver )
var windowlist = driver.WindowHandles;
Console.WriteLine(windowlist.Count);
//loop through the list and switchto the window, and then check the url
if(windowlist.Count > 1)
{
foreach (var item in windowlist)
{
driver.SwitchTo().Window(item);
Console.WriteLine(driver.Url);
if(driver.Url.Contains("https://www.bing.com"))
{
driver.Close(); //use the Close method to close the window. The Quit method will close the browser window and dispose the webdriver.
}
}
}
Console.ReadKey();
}
Console.ReadKey();
}
I'm trying to launch a specific URL using Firefox. But I'm only able to open Firefox browser and not able to launch that URL.
class BrowserHelper
{
IWebDriver driver;
string path = Path.Combine(Environment.CurrentDirectory, #"gecko\\");
public void Navigate(string url)
{
path = path.Replace(#"\", #"\\");
var driverService = FirefoxDriverService.CreateDefaultService(path);
driverService.HideCommandPromptWindow = true;
if (driver == null)
{
driver = new FirefoxDriver(driverService);
}
driver.Url = url;
driver.Navigate().GoToUrl(driver.Url);
driver.Manage().Window.Maximize();
}
}
class Realtest
{
BrowserHelper BH = new BrowserHelper();
public void test()
{
string search ="apple";
BH.Navigate("https://www.google.com/search?q=" + search);
}
}
And I can only get this page:
Here's the final URL I want to launch: https://www.google.com.sg/search?q=apple
Any suggestions? Thanks in advance.
I have tried the below code (in Java), and it's working fine by launching the browser and loading the URL also.
System.setProperty("webdriver.gecko.driver","Drivers/geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.google.com.sg/search?q=apple");
So I feel the problem is with geckodriver version and FireFox browser installed in your local machine. I would suggest you update FireFox and geckodriver to the latest version.
There is also a pretty easy solution using the command line with c#.
Simply execute the following command to open a new Firefox Tab with the given URL:
start firefox wikipedia.de
You can also start a new Firefox instance if you wish:
start firefox -new-instance wikipedia.de
Last but not least the .Net Code to execute the commands in CLI:
System.Diagnostics.Process.Start(new System.Diagnostics.ProcessStartInfo()
{
Arguments = "/c start firefox wikipedia.de",
CreateNoWindow = true,
FileName = "CMD.exe"
});
There is also a lot of other stuff that can be done with Firefox commandLine paramters. You an find all of them here:
https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options?redirectlocale=en-US&redirectslug=Command_Line_Options
This also works with chrome and opera, simply call
start opera wikipedia.de
instead of firefox.
You do not need to set driver.Url, remove that line.
driver.Navigate().GoToUrl(url);
driver.Manage().Window.Maximize();
Also, if you simply want to launch a single URL without interacting with the page, then Selenium is overkill.
My company has purchased the CoolUtils TotalPDFPrinterX from https://www.coolutils.com/TotalPDFPrinterX
I make an HTTP PUT from Postman to the API and I get “Could not get any response”.
When running on my Windows machine the PDF prints fine however on the server the site crashes and in the event log I get the error "A process serving application pool '[MY_APP_POOL]' failed to respond to a ping. The process id was '[MY_PROCESS_ID]'."
Here is my C# code:
PDFPrinterX ppx = new PDFPrinterX();
ppx.Print(fileName, printerName, "-ap Default");
if (ppx.ErrorMessage != null)
{
WriteToSQL(id, false, ppx.ErrorMessage, 2);
Console.WriteLine(ppx.ErrorMessage);
}
By writing to the event log I know the site crashes on this line: PDFPrinterX ppx = new PDFPrinterX(); I have also surrounded the above code with a try catch and no exception is thrown. The site still crashes.
Things I have tried:
Uninstalling and Reinstalling the CoolUtils software
Giving EVERYONE Full control to the site folder and the CoolUtils program folder
Creating a C# desktop application using the same code. THIS WORKS FINE ON THE SERVER. It's just the ASP site that crashes.
Does anyone know what might be causing this?
The more I research this thing online the more I'm inclined to say that ActiveX which is the X in PDFPrinterX doesn't seem to work well when hosted in IIS.
I've seen a few forums where they say it works fine when they debug on localhost but when deployed to server is crashes.
...works fine when used inside localhost(Visual studio)
One of their feature pages shows that it requires Win 2000/NT/XP/2003/Vista/7
You should look into whether your server supports ActiveX components that can work in conjunction with IIS.
Looking at one of their other products support page: TotalPDFConverterX:
the following note in my opinion may also apply to TotalPDFPrinterX, given its dependency on ActiveX as well.
Note: Pay attention to some details during installation Total PDF Converter X:
Do not forget to register ActiveX in your web-server account.
Total PDF Converter X supports only Internet Explorer, Mozilla and Firefox browsers.
ActiveX works only with 32-bit internet information server. 64-bit server is not supported. Use command line version instead.
Thanks to #Nkosi I was able to find a workaround.
ActiveX works only with 32-bit internet information server. 64-bit server is not supported. Use command line version instead.
Our IIS server is 64 bit so that is what probably caused the site to hang up.
Buttt... the command line still worked in printing the PDFs on the server.
Client side code (makes the HTTP POST):
private void SendToPrinter(string fileName, string printerName, int id, decimal documentSequence)
{
// use http client to make a POST to the print api
using (var client = new HttpClient())
{
// compile the values string to transfer in POST
// should finish to look something like this:
// C:\print.pdf&PRTFTW_OFIT&ValShip-155320-1
var values = new Dictionary<string, string>
{
{ "", fileName + "&" + printerName + "&ValShip-" + id + "-" + documentSequence},
};
// URL encode the values string
var content = new FormUrlEncodedContent(values);
// make the POST
// DEBUG
var response = client.PostAsync("http://localhost:54339/api/print", content);
// retrieve the response
var responseString = response.Result.ToString();
}
}
Server side code (receives the HTTP POST):
using System;
using System.Net.Http;
using System.Web;
using System.Web.Http;
namespace api.valbruna.print.Controllers
{
public class PrintController : ApiController
{
// POST api/print
public HttpResponseMessage Post(HttpRequestMessage request)
{
try
{
// parse the content recieved from the client
var content = request.Content.ReadAsStringAsync().Result;
// decode the content, certain characters such as
// '&' get encoded to URL lingo such as '%26'
content = HttpUtility.UrlDecode(content);
// split the string into 3 seperate parts
String[] str = content.Split('&');
// remove the equal sign from the first string
str[0] = str[0].Trim('=');
// compile the arguments command line string
// should finish to look something like this:
// "C:\Program Files (x86)\CoolUtils\Total PDF PrinterX\PDFPrinterX.exe" "C:\print.pdf" -p"\\PRINTERS\PRTFTW_OFIT" -ap Default -log "C:\inetpub\logs\CoolUtils\log-ValShip-155320-4.txt" -verbosity detail"
String arguments = "\"" + str[0] + "\" -p\"\\\\PRINTERS\\" + str[1] +
"\" -ap Default -log \"C:\\inetpub\\logs\\CoolUtils\\log-" + str[2] +
".txt\" -verbosity detail";
// file location for PDFPrinterX.exe
String file = #"C:\Program Files (x86)\CoolUtils\Total PDF PrinterX\PDFPrinterX.exe";
// start the process
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
startInfo.FileName = file;
startInfo.Arguments = arguments;
process.StartInfo = startInfo;
process.Start();
return new HttpResponseMessage() { Content = new StringContent(content) };
}
catch (Exception e)
{
return new HttpResponseMessage() { Content = new StringContent(e.Message) };
}
}

I need to know the process ID of the browser (or tab if google chrome) which execute the IWebDriver GoToUrl method.
I found this on stack overflow: Find PID of browser process launched by Selenium WebDriver
However, my browser is already opened. For the worse case, if it's google chrome, I need the process ID of the tab which went on the URL.
Reason
I use Fiddler to capture requests, and when I capture the requests, I can access the process ID. I need to match it with browser which did the GoToUrl.
If you ran the code that executed IWebDriver to start the Chrome browser then you can add more code that will get the PID for you.
You don't state which language you are using. Below is an example you can use for C# and Selenium. There would be the same implementation for other languages (like Java) but I am only working in C#.
Chrome allows you to supply your own user-defined command-line arguments. So you can add an argument named "scriptpid-" with the PID (Windows Process ID) of your currently running program. ChromeDriver passes your argument to Chrome in the command-line. Then using Windows WMI calls retrieve this PID from the command-line of the running Chrome ...
public static IntPtr CurrentBrowserHwnd = IntPtr.Zero;
public static int CurrentBrowserPID = -1;
ChromeOptions options = new ChromeOptions();
options.AddArgument("scriptpid-" + System.Diagnostics.Process.GetCurrentProcess().Id);
IWebDriver driver = new ChromeDriver(options);
// Get the PID and HWND details for a chrome browser
System.Diagnostics.Process[] processes = System.Diagnostics.Process.GetProcessesByName("chrome");
for (int p = 0; p < processes.Length; p++)
{
ManagementObjectSearcher commandLineSearcher = new ManagementObjectSearcher("SELECT CommandLine FROM Win32_Process WHERE ProcessId = " + processes[p].Id);
String commandLine = "";
foreach (ManagementObject commandLineObject in commandLineSearcher.Get())
{
commandLine += (String)commandLineObject["CommandLine"];
}
String script_pid_str = (new Regex("--scriptpid-(.+?) ")).Match(commandLine).Groups[1].Value;
if (!script_pid_str.Equals("") && Convert.ToInt32(script_pid_str).Equals(System.Diagnostics.Process.GetCurrentProcess().Id))
{
CurrentBrowserPID = processes[p].Id;
CurrentBrowserHwnd = processes[p].MainWindowHandle;
break;
}
}
CurrentBrowserHwnd should contain the HWND of your Chrome window.
CurrentBrowserPID should contain the Process ID of your Chrome window.
I've been trying for a couple weeks now to run a non-elevated web browser from an elevated process, I have tried various things, duplicating the explorer token, using the WinSafer Apis mentioned here and various other techniques that all failed. Finally I decided to use Microsoft's suggestion of using the Task Scheduler to run the application.
I used the Task Scheduler Managed Wrapper, at first I tried running explorer.exe and passing the url as a command but that did not work so I created a dummy executable that'll launch the site using Process.Start.
Here is how I create the task:
public static void LaunchWin8BrowserThroughTaskScheduler(string sURL)
{
String RunAsUserExecPath = AppDomain.CurrentDomain.BaseDirectory + "URLLaunch.exe";
String Command = string.Format("-w \"{0}\"", sURL);
using (TaskService ts = new TaskService())
{
TaskDefinition td = ts.NewTask();
td.RegistrationInfo.Description = "URL Launch";
td.Principal.LogonType = TaskLogonType.InteractiveToken;
TimeTrigger trigger = new TimeTrigger(DateTime.Now.AddSeconds(2))
{
Enabled = true,
EndBoundary = DateTime.Now.AddSeconds(10)
};
td.Triggers.Add(trigger);
td.Actions.Add(new ExecAction( RunAsUserExecPath, Command, null));
td.Settings.StartWhenAvailable = true;
//Delete the task after 30 secs
td.Settings.DeleteExpiredTaskAfter = new TimeSpan(0,0,0,30);
ts.RootFolder.RegisterTaskDefinition("URL Launch", td, TaskCreation.CreateOrUpdate, null, null, TaskLogonType.InteractiveToken);
}
}
and this is the code to my dummy executable:
static void Main(string[] args)
{
if(args.Length<=1)
return;
string sCmd = args[0];
string sArg = args[1];
if(string.IsNullOrEmpty(sCmd)||string.IsNullOrEmpty(sArg))
return;
switch (sCmd)
{
case "-w":
{
Process prs = Process.Start(sArg);
}
break;
}
}
This method is working, and the browser is indeed launched non-elevated and I was able to confirm that by checking the Elevated column in Windows 8's task manager.
The only nuance here is that the browser is not launched as the top most window, it is running in the background and I think its got to do with the fact that its being run through task scheduler.
This is causing me problems especially with Modern UI browsers because Windows does not switch to them when a page is launched. I can see that the page has been successfully launched in Chrome, for example, while running in Windows 8 mode, but the fact that it does not switch to the browser just defies the whole purpose of this workaround.
I thought about using SetForegroundWindow but sadly running a URL like the example above or through explorer.exe, Process.Start returns null.
I was wondering if someone can help me fix this and be able to run the browser in foreground.
Regards
I've been able to solve the issue with a very simplistic method.
Just write a shortcut file to somewhere like the TempFolder and execute it through explorer.exe likes so:
public static void GoURL(string url)
{
string sysPath = Environment.GetFolderPath(Environment.SpecialFolder.System);
string ExplorerPath = Path.Combine(Directory.GetParent(sysPath).FullName,
"explorer.exe");
string TempDir = Environment.GetFolderPath(Environment.SpecialFolder.InternetCache);
string shortcutPath = Path.Combine(TempDir, "Mylink.url");
urlShortcutToTemp(url, shortcutPath);
System.Diagnostics.Process.Start(ExplorerPath, shortcutPath);
}
private static void urlShortcutToTemp(string linkUrl, string shortcutPath)
{
using (StreamWriter writer = new StreamWriter(shortcutPath))
{
writer.WriteLine("[InternetShortcut]");
writer.WriteLine("URL=" + linkUrl);
writer.Flush();
}
}
The same solution can be applied to executables with lnk shortcuts.
