Java + Selenium Automation Example:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.By;

public class LoginTest {
    public static void main(String[] args) {
        // Set up WebDriver
        WebDriver driver = new ChromeDriver();
        driver.get("https://demo.com/login");

        // Find elements and interact
        driver.findElement(By.id("username")).sendKeys("tester");
        driver.findElement(By.id("password")).sendKeys("password123");
        driver.findElement(By.id("login-btn")).click();

        // Verify login success
        String expectedTitle = "Dashboard";
        String actualTitle = driver.getTitle();

        if (actualTitle.equals(expectedTitle)) {
            System.out.println("Login Test: PASSED");
        } else {
            System.out.println("Login Test: FAILED");
        }

        driver.quit();
    }
}

Key Features:
✅ Java + Selenium WebDriver
✅ Element locators (ID, XPath, CSS)
✅ Browser automation
✅ Assertions and verification

TestNG Framework Example:

import org.testng.annotations.Test;
import org.testng.annotations.BeforeMethod;
import org.testng.Assert;

public class LoginTestNG {

    @BeforeMethod
    public void setUp() {
        // Setup WebDriver
        System.out.println("Setting up browser...");
    }

    @Test(priority = 1)
    public void testValidLogin() {
        // Test valid login
        boolean result = login("tester", "password123");
        Assert.assertTrue(result, "Valid login should succeed");
    }

    @Test(priority = 2)
    public void testInvalidLogin() {
        // Test invalid login
        boolean result = login("wrong", "wrong");
        Assert.assertFalse(result, "Invalid login should fail");
    }

    @Test(priority = 3, dependsOnMethods = {"testValidLogin"})
    public void testLoginAfterLogout() {
        // Test login after logout
        logout();
        boolean result = login("tester", "password123");
        Assert.assertTrue(result, "Login after logout should work");
    }

    @Test(expectedExceptions = Exception.class)
    public void testLoginWithEmptyCredentials() {
        // Test empty credentials - should throw exception
        login("", "");
    }

    private boolean login(String username, String password) {
        // Login logic
        return username.equals("tester") && password.equals("password123");
    }

    private void logout() {
        // Logout logic
        System.out.println("Logging out...");
    }
}

Key Features:
✅ TestNG annotations
✅ Test prioritization
✅ Dependencies between tests
✅ Exception testing
