Sample java application to test using headless selenium server

 

public class App 
{
    private static void googleExampleThatSearchesFor(final String searchString) throws MalformedURLException {
        WebDriver driver =
                new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), DesiredCapabilities.chrome());

        WebElement searchField = driver.findElement(By.name("q"));
        searchField.sendKeys(searchString);
        System.out.println("Page title is: " + driver.getTitle());
        searchField.submit();

        (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver driverObject) {
                return driverObject.getTitle().toLowerCase().startsWith(searchString.toLowerCase());
            }
        });

How to create a headless Selenium Server vagrant box

Vagrantfile:

Vagrant.configure(“2”) do |config|
config.vm.box = “bento/ubuntu-16.04”
config.ssh.forward_agent = true

config.vm.network “forwarded_port”, guest: 4444, host: 4444

config.vm.provision ‘setup’, type: ‘shell’, path: ‘setup.sh’
config.vm.provision ‘cleanup’, type: ‘shell’, path: ‘cleanup’

end
