💡 Key Insight: Android + Selenium opens
3x more career paths!

Basic Selenium Automation Framework (Java):

// Base Test Class
public class BaseTest {
    WebDriver driver;

    @BeforeMethod
    public void setUp() {
        driver = new ChromeDriver();
        driver.manage().window().maximize();
        driver.get("https://example.com");
    }

    @AfterMethod
    public void tearDown() {
        driver.quit();
    }
}

// Login Test
public class LoginTest extends BaseTest {
    @Test
    public void testValidLogin() {
        driver.findElement(By.id("username")).sendKeys("tester");
        driver.findElement(By.id("password")).sendKeys("password123");
        driver.findElement(By.id("login-btn")).click();

        String expected = "Dashboard";
        String actual = driver.getTitle();
        Assert.assertEquals(actual, expected);
    }

    @Test
    public void testInvalidLogin() {
        driver.findElement(By.id("username")).sendKeys("invalid");
        driver.findElement(By.id("password")).sendKeys("invalid");
        driver.findElement(By.id("login-btn")).click();

        String error = driver.findElement(By.id("error-msg")).getText();
        Assert.assertTrue(error.contains("Invalid"));
    }
}

Key Components:
✅ WebDriver setup
✅ TestNG annotations
✅ Assertions
✅ Page Object Model

Page Object Model Framework (Android Devs Love This):

// Page Object Class
public class LoginPage {
    WebDriver driver;

    // Locators
    By usernameField = By.id("username");
    By passwordField = By.id("password");
    By loginButton = By.id("login-btn");

    // Constructor
    public LoginPage(WebDriver driver) {
        this.driver = driver;
    }

    // Methods - like Android View interactions!
    public void enterUsername(String username) {
        driver.findElement(usernameField).sendKeys(username);
    }

    public void enterPassword(String password) {
        driver.findElement(passwordField).sendKeys(password);
    }

    public void clickLogin() {
        driver.findElement(loginButton).click();
    }

    public String getPageTitle() {
        return driver.getTitle();
    }
}

// Test using Page Objects
public class LoginTest {
    @Test
    public void testLogin() {
        LoginPage loginPage = new LoginPage(driver);
        loginPage.enterUsername("tester");
        loginPage.enterPassword("password123");
        loginPage.clickLogin();

        Assert.assertEquals(loginPage.getPageTitle(), "Dashboard");
    }
}

Android Developers will find this familiar:
- Page Objects = Activities/Fragments
- Locators = View IDs
- Methods = UI interactions

💡 Key Insight: The pattern is
identical to Android UI testing!
