When running tests in headless chromedriver, the tests fail with errors like "Element not interactable", "element click intercepted" (in the same places). But when I run normal chromedriver the tests pass. I identify elements by XPath.
Why is this happening and how can it be fixed?
Examples of my Chromedriver settings:
Headless:
var options = new ChromeOptions();
options.AddArguments("headless");
driver = new ChromeDriver(options);
Normal:
driver = new OpenQA.Selenium.Chrome.ChromeDriver();

I am trying to automate testing of an electron application (from third party vendor) using Selenium and C# and am getting the error: OpenQA.Selenium.WebDriverException : Cannot start the driver service on http://localhost:. Attached is the piece of code.
ChromeOptions options = new ChromeOptions();
ChromeDriverService chromeService = ChromeDriverService.CreateDefaultService(#"C:\Selenium\chromedriver_win32_1",
#"<path to exe of electron application>");
options.AddArgument("–no-sandbox");
options.AddArgument("–disable-dev-shm-usage");
driver = new ChromeDriver(chromeService, options, TimeSpan.FromSeconds(180));
Actual result:
OpenQA.Selenium.WebDriverException : Cannot start the driver service on http://localhost:
Expected Result: driver instance is created successfully
NOTE: The electron application is launched successfully. Also when I remove the path to exe of electron application there is no error and driver instance is created successfully
There can be different problems but when I am testing electron apps, I prefer to use following kind of options to set binary.
Maybe following kind of code block can solve your issue.
ChromeOptions options = new ChromeOptions();
options.setBinary(binaryPath);
options.addArguments("--app=" + argPath);
options.AddArgument("–no-sandbox");
options.AddArgument("–disable-dev-shm-usage");
options.setCapability("chromeOptions", options);
driver = new ChromeDriver(options);
I want to load a new Selenium ChromeDriver that is using Chrome as if I open Chrome from my dock (Essentially it'll have all my extensions, history, etc.)
When I use the following code:
ChromeOptions options = new ChromeOptions();
options.AddArgument("user-data-dir=C:\\Users\\User\\AppData\\Local\\Google\\Chrome\\User Data\\");
options.AddArgument("disable-infobars");
options.AddArgument("--start-maximized");
ChromeDriver chromeDriver = new ChromeDriver(options);
It loads the Chrome browser with me signed into my Gmail and with all my extensions, just like I want, but the rest of my code:
chromeDriver.Navigate().GoToUrl("https://www.youtube.com/");
doesn't execute. But when I use the following
ChromeOptions options = new ChromeOptions();
options.AddArgument("user-data-dir=C:\\Users\\Andrea\\AppData\\Local\\Google\\Chrome\\User Data\\Default");
options.AddArgument("disable-infobars");
options.AddArgument("--start-maximized");
ChromeDriver chromeDriver = new ChromeDriver(options);
The rest of my code executes perfectly (Notice the 'Default' added to the end of the first Argument). Any tips or suggestions on how I can get the first block of code (The one without 'Default' on the end) to execute the rest of my program would be great. Thanks!
I know this is an old question, but what worked for me is to do remove the "C:\" and replace all of the backslashes with forward slashes. So, with that from the original question, this should work to load the default profile:
options.AddArgument("user-data-dir=/Users/User/AppData/Local/Google/Chrome/User Data");
The Default Chrome Profile which you use for your regular tasks may contain either/all of the following items:
History
Bookmarks
Cookies
Extensions
Themes
Customized Fonts
All these configurations untill and unless are part of your Test Specification it would be a overkill to load them into the session initiated by Selenium WebDriver. Hence it will be a better approach if you create a dedicated New Chrome Profile for your tests and configure it with all the required configuration.
Here you will find a detailed discussion on How to create and open a Chrome Profile
Once you have created the dedicated New Chrome Profile for your tests you can easily invoke the Chrome Profile as follows:
ChromeOptions options = new ChromeOptions();
options.AddArgument("user-data-dir=C:\\Users\\User\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 2");
options.AddArgument("disable-infobars");
options.AddArgument("--start-maximized");
ChromeDriver chromeDriver = new ChromeDriver(options);
chromeDriver.Navigate().GoToUrl("https://www.youtube.com/");
Here you will find a detailed discussion on How to open URL through default Chrome profile using Python Selenium Webdriver
I have the same issue. I don't know how to fix it, I guess the root cause is white space in profile path.
I know a workaround for this. Just copy the C:\\Users\\Andrea\\AppData\\Local\\Google\\Chrome\\User Data to c:\myUserData (no space in the path).
Then add the argument.
options.AddArgument("user-data-dir=C:\\myUserData");
This is an Old question, but if you are facing this issue, all you have to do is close all tabs, Just shut down the chrome window..
Selenium can't use the data since it is already in use.
Hope you fond this helpful.
I am running chromedriver on windows server 2016 with IIS, i have my test project installed and invoking it with an MVC5 API. That all seems fine but chromedriver and chrome.exe only seems to open as a background processes.
The same code opens these fine locally, i am not using any of the driver flags for headless browsing either. if i return the drive page source i can see that chromedriver went to google and returned the correct html in my API.
It just does not work for normal / non headless tests with google or our application.
var driver = x.StartWebDriver();
driver.Manage().Window.Maximize();
driver.Navigate().GoToUrl("http://www.google.com");
return driver.PageSource;
Any ideas?
I have got the same issue and this is how I solve this:
Open a command prompt and navigate to your ChromeDriver location.
Execute chromedriver.exe and you will see the message as below.
image here
In the image above you see chrome driver is listening on port 9515.
Now change your code as below, rebuild and call you api to execute your test.
ChromeOptions options = new ChromeOptions();
//set your chromeoptions here
Uri uri = new Uri("http://localhost:**9515");
_driver = new RemoteWebDriver(uri, options);
Open the chrome driver and note the port number(eg:5353)
In java:
System.setProperty(chromeDriverName, chromeDriverLocation);
ChromeOptions options = new ChromeOptions();
URL uri = new URL(chromeDriverPort);//http://localhost:5353
WebDriver driver = new RemoteWebDriver(uri, options);
your problem gets solved in is server.
I'm learning Selenium from the scratch and trying to run a test case on Firefox 50.0.1 using geckodriver I installed in VS2015 by selecting Selenium.WebDriver.GeckoDriver.Win64
However, when running the test I got an exception
Cannot start the driver service on localhost
What am I missing?
I was following some tutorials and performed step by step walk-through.
This is my code:
[TestMethod]
public void WebDriverSample()
{
IWebDriver webDriver;
//IWebDriver webDriver = new InternetExplorerDriver();
//Thread.Sleep(1000);
//webDriver.Dispose();
//webDriver = new ChromeDriver();
//Thread.Sleep(1000);
//webDriver.Dispose();
webDriver = new FirefoxDriver();
Thread.Sleep(1000);
webDriver.Dispose();
}
When using Firefox 47.0.2, I did not need to use geckodriver at all and it worked just fine.
Now, since browsers are getting updated, at some point I need to start using new versions. So, I need to find out what to do in order to be able to adapt to new changes and use geckodriver
Any suggestons?
When I create a new chrome driver in Selenium while Google Chrome is already running AND I am referencing the users settings/data (via user-data-dir). A new Chrome window will open, but my application will hang. The ChromeDriver console will display the following error each second: DevTools Request: 127.0.0.1:12585/json/version. DevTools request failed
Screenshot:
Code to instantiate the driver:
ChromeDriverService driverService = ChromeDriverService.CreateDefaultService();
//driverService.HideCommandPromptWindow = true;
driverService.EnableVerboseLogging = true;
string path = Environment.ExpandEnvironmentVariables("%LOCALAPPDATA%\\Google\\Chrome\\User Data");
ChromeOptions options = new ChromeOptions();
options.AddArguments("user-data-dir=" + path);
options.AddArguments("--start-maximized");
options.AddArguments("--disable-extensions");
IWebDriver driver = new ChromeDriver(driverService, options);
This will work perfectly fine in every instance if I do not try and load user settings/data. If I am trying to load user setting/data it will only work if there is no instance of Chrome running on the device already.
Versions:
Selenium v 2.47.0
ChromeDriver v 2.16.333243
Chrome v44.0.2403
What can I do to resolve this?
If anyone was looking for answer like me;
https://bugs.chromium.org/p/chromedriver/issues/detail?id=2443
This behavior is by design. Two instances of Chrome can't use the same user-data-dir at the same time. Otherwise they would try to update the same set of files and cause corruptions. So if an instance is already running, attempting to start another instance using the same user-data-dir will cause the second instance to ask the first instance to open a new window, and then the second instance exits.
