Lets create a TestNG project

2. Create a class as TestNGClass

3. Create following class

   1.LoginPage.class

   2.HomePage.class

   3.FBLoginTest.class

Here goes the code:

LoginPage class

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;

public class LoginPage {

    @FindBy(id = "email")
    private WebElement username;
    
    @FindBy(id = "pass")
    private WebElement password;
    
    @FindBy(xpath = ".//input[@data-testid='royal_login_button']")
    private WebElement login;
    
    WebDriver driver;
    
    public LoginPage(WebDriver driver){
        this.driver = driver;
         PageFactory.initElements(driver, this);
    }
    public void enterUserName(String name){
        username.clear();
        username.sendKeys(name);
    }
    
    public void enterPassword(String passwrd){
        password.clear();
        password.sendKeys(passwrd);
    }
    

    public HomePage clickLoginButton(){
        login.click();
        return new HomePage(driver);
    }
}

HomePage class.

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;

public class HomePage {

    @FindBy(id = "userNavigationLabel")
    private WebElement userDropdown;
    
    WebDriver driver;
    
    public HomePage(WebDriver driver){
        this.driver = driver;
        PageFactory.initElements(driver, this);
    } 
    
    public boolean isUserLoggedIn(){
        return userDropdown.isDisplayed();
    }
    
}

FBLoginTest class

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.Test;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.AfterClass;

import com.testng.pages.HomePage;
import com.testng.pages.LoginPage;

public class FBLoginTest {
    
    WebDriver driver;
    LoginPage loginPage;
    HomePage homePage;
    
    @BeforeClass
    public void openFBPage(){
        driver = new FirefoxDriver();
        driver.get("https://www.facebook.com/");
        loginPage = new LoginPage(driver);
    }
    
    @Test
    public void loginToFB(){
        loginPage.enterUserName("");
        loginPage.enterPassword("");
        homePage = loginPage.clickLoginButton();
        Assert.assertTrue(homePage.isUserLoggedIn());
    }
    
    @AfterClass
    public void closeBrowser(){
        driver.quit();
    }

}

Here comes the testng xml: Right click on Project create a xml file and copy paste this content.

<?xml version="1.0" encoding="UTF-8"?>
<suite name="Suite">
  <test name="Test">
    <classes>
      <class name="com.testng.FBLoginTest"/>
    </classes>
  </test> <!-- Test -->
</suite> <!-- Suite -->
