I want to try out headless chrome, but I am running into this issue, that I can't start the driver in headless mode. I was following google documentation. am I missing something ? The code execution gets stuck in var browser = new ChromeDriver();
line
Here is my code:
var chromeOptions = new ChromeOptions { BinaryLocation = @"C:\Users\2-as Aukstas\Documents\Visual Studio 2017\Projects\ChromeTest\ChromeTest\bin\Debug\chromedriver.exe", DebuggerAddress = "localhost:9222" }; chromeOptions.AddArguments(new List<string>() {"headless", "disable-gpu" }); var browser = new ChromeDriver(chromeOptions); browser.Navigate().GoToUrl("https://stackoverflow.com/"); Console.WriteLine(browser.FindElement(By.CssSelector("#h-top-questions")).Text);
Post version 59, Chrome supports headless execution. ChromeOptions class is utilized to modify the default characteristics of the browser. The addArguments method of the ChromeOptions class is used for headless execution and headless is passed as a parameter to that method.
Which command starts the google chrome web browser in headless mode? As we have already seen, you just have to add the flag –headless when you launch the browser to be in headless mode. With CLI (Command Line Interface), just write: chrome \<br> – headless \ # Runs Chrome in headless mode.
ChromeOptions options = new ChromeOptions() options. addArgument("headless"); ChromeDriver driver = new ChromeDriver(options); In the above code, the browser is instructed to run in the headless mode using the addArgument() method of the ChromeOptions class provided by the Selenium WebDriver.
The easiest way to get started with headless mode is to open the Chrome binary from the command line. If you've got Chrome 59+ installed, start Chrome with the --headless flag: Note: Right now, you'll also want to include the --disable-gpu flag if you're running on Windows. See crbug.com/737678. chrome should point to your installation of Chrome.
While working with Selenium Client 3.11.x, ChromeDriver v2.38 and Google Chrome v65.0.3325.181 in Headless mode you have to consider the following points : You need to add the argument --headless to invoke Chrome in headless mode. For Windows OS systems you need to add the argument --disable-gpu
All major browsers like Chrome, Firefox, Microsoft Edge support headless mode. Running automated UI scripts in a headless browser may lower test execution time but not that much significantly. You can experience a little better performance during automated UI scripts execution.
You can download Chrome Canary and use headless with it. After installation set BinaryLocation to point to chrome canary also comment out the DebuggerAddress line (it forces chrome to timeout): Show activity on this post. For you that did not get reference for ChromeDriver. Use this step :
UPDATE
Chrome version 60 is out so all you need to do is to download Chromdriver and Selenium via Nuget and use this simple code and everything works like a charm. Amazing.
using OpenQA.Selenium; using OpenQA.Selenium.Chrome; ... var chromeOptions = new ChromeOptions(); chromeOptions.AddArguments("headless"); using (var browser = new ChromeDriver(chromeOptions)) { // add your code here }
DATED
There is a solution until the official release of Chrome 60 will be released. You can download Chrome Canary and use headless with it. After installation set BinaryLocation to point to chrome canary also comment out the DebuggerAddress line(it forces chrome to timeout):
var chromeOptions = new ChromeOptions { BinaryLocation = @"C:\Users\2-as Aukstas\AppData\Local\Google\Chrome SxS\Application\chrome.exe", //DebuggerAddress = "127.0.0.1:9222" }; chromeOptions.AddArguments(new List<string>() { "no-sandbox", "headless", "disable-gpu" }); var _driver = new ChromeDriver(chromeOptions);
