Question

public static void main(String[] args) throws IOException {
    RbnRunner runner = new RbnRunner();
    runner.run();

}

public void run() throws IOException {

    System.setProperty("webdriver.chrome.driver", "/Users/me/samples/Adam_milford/src/chromedriver");

    WebDriver driver = new ChromeDriver();

but when I want to init a headless selenium driver instead of Chrome driver, the code failes:

public static void main(String[] args) throws IOException {
    WebDriver driver = new HtmlUnitDriver();

why is that?

Usually, the actual problem is the one shown at the `Caused By:` line; a `ClassNotFoundException`. In case there are several `Cause By:` clauses, focus on the last one. — SJuan76, Oct 11 '16 at 08:32
