Answer 1

What are the versions of your Chrome browser, chromedriver and Selenium? I tried with:

1. Chrome Version 62.0.3202.75 (Official Build) (64-bit)
2. chromedriver 2.33
3. Selenium 3.6.0

The following code:

    System.setProperty("webdriver.chrome.driver", "/pathTo/chromedriver);

    ChromeOptions chromeOptions = new ChromeOptions();
    chromeOptions.addArguments("--headless");

    ChromeDriver driver = new ChromeDriver(chromeOptions);
    driver.get("https://the-internet.herokuapp.com/login");
    System.out.println(driver.getTitle());

Note: In current versions of Selenium and ChromeDriver replace:

    chromeOptions.addArguments("--headless");

with

    chromeOptions.setHeadless(true);

Ref: https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/chrome/ChromeOptions.html#setHeadless-boolean- Also you must set Window size otherwise it renders in mobile mode and you may not get certain elements in the page.

    chromeOptions.addArguments("--window-size=1200x600");

Tested on chromedriver 2.42.591071 with Selenium 3.14.0

The output:

The Internet

Take a look to Getting Started with Headless Chrome about the browser support versions.

Answer 2

options.addArguments("headless");
capabilities.setCapability(ChromeOptions.CAPABILITY, options);

This worked for me. Chromedriver Version:2.37
