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();

但是当我想创建一个无头的selenium驱动程序而不是Chrome驱动程序时，代码就会失败：

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

为什么会这样？
