Not able to open Chrome headless from Selenium

问题

I am using maven here.Here is my Selenium code:

DesiredCapabilities capb = DesiredCapabilities.chrome();
    capb.setCapability("chrome.binary","/Applications/Google Chrome.app/Contents/MacOS/Google Chrome");
    ChromeOptions options = new ChromeOptions();
    options.addArguments("--headless","--disable-gpu", "--no-sandbox","--remote-debugging-port=9222");
    capb.setCapability(ChromeOptions.CAPABILITY, options);
    System.setProperty("webdriver.chrome.driver","/Users/nitinkumar/TEST/chromedriver");
    try{
    ChromeDriver driver = new ChromeDriver(capb);
    driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
    driver.get("https://qa.cmnetwork.co");
    driver.quit();
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }

when I run "mvn test" it starts the chrome in GUI mode. but It should open in Headless mode. I have chrome vesrion 59.0, OS X yosemite(10.10.5), chromedriver 2.30 and Selenium 3.4.0.

回答1:

It won't open in GUI mode. Just the chrome launcher icon will be opened. And it is an expected behaviour.

You have to remove the argument --remote-debugging-port. That will block the launched headless Chrome. So the script will never move forward.And you will get a chrome not reachable error

So change the arguments like

options.addArguments("--headless","--disable-gpu", "--no-sandbox");

Also, there is no need for --no-sandbox. As per Official doc only --headless and --disable-gpu flags are enough

Unless you have multiple versions of chrome installed, there is no need for DesiredCapabilities as well.

So the simple code for headless-chrome

    ChromeOptions options = new ChromeOptions();
    options.addArguments("--headless","--disable-gpu");
    System.setProperty("webdriver.chrome.driver","/Users/nitinkumar/TEST/chromedriver");

    ChromeDriver driver = new ChromeDriver(options);
    driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
    driver.get("https://qa.cmnetwork.co");
    driver.quit();
