Serenity support for Firefox Gecko driver and Chrome driver

[Srinivas Aditya]

I am new to Serenity BDD framework. I was given a test automation framework that is not in use for quite a while.

I have latest Firefox ver 59 and Chrome ver 66 on my machine. I have Selenium 3.11. I know the Selenium 3 has to use the gecko driver for firefox.

The problem I am facing is that Selenium script launches firefox but is not navigating to the page and get this exception

FAILED net.thucydides.core.webdriver.UnsupportedDriverException

My serenity-core in dependencies is latest version serenity-core:1.9.14

I want to specify the gecko driver and test but don't know how to do it in my scenario below. I would request for help in configuring the gecko driver in this specific scenario. Following is my project structure

Features package -

@RunWith(SerenityRunner.class)
public class TestCaseName

@Managed
WebDriver driver;

@Steps
LoginSteps loginSteps

@Test
public void userLogin() 
{    
    loginSteps.userLogsIn();

}

Step class -
LoginPage loginPage

@Step
public void usedLogsIn() 
{ 
    loginPage.open();
}

PageObject class -
@DefaultUrl("The application url is mentioned here")
public class LoginPage extends net.serenitybdd.core.pages.PageObject

net.serenitybdd.core.pages.PageObject class has the following open method -
    final public void open() {
    open(OpenMode.CHECK_URL_PATTERNS)
    }
Could somebody please clarify the below things
1. Are latest versions of Firefox and Chrome supported?
2. If supported, where should I specify the gecko driver and chrome driver in the above code that I am using? Generally we do it using System.property. But I am not aware where to mention them in the above scenario.
