Building an automation framework

Building an automation framework

Learn to build a Java automation framework. Set up project structure. Create reusable components. Implement test cases. Integrate with CI/CD pipelines.

Examples

// Example 1: Setting up project structure
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class TestBase {
    protected WebDriver driver;
    public void setup() {
        System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
        driver = new ChromeDriver();
    }
    public void teardown() {
        if (driver != null) {
            driver.quit();
        }
    }
}

// Example 2: Creating reusable components
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
public class LoginPage {
    private WebDriver driver;
    private By usernameField = By.id("username");
    private By passwordField = By.id("password");
    private By loginButton = By.id("login");
    
    public LoginPage(WebDriver driver) {
        this.driver = driver;
    }
    
    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();
    }
}

// Example 3: Implementing test cases
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import static org.junit.Assert.assertTrue;
public class LoginTest extends TestBase {
    private LoginPage loginPage;
    
    @Before
    public void setUp() {
        setup();
        loginPage = new LoginPage(driver);
        driver.get("https://example.com/login");
    }
    
    @Test
    public void testLoginSuccess() {
        loginPage.enterUsername("testuser");
        loginPage.enterPassword("testpass");
        loginPage.clickLogin();
        assertTrue(driver.getTitle().contains("Dashboard"));
    }
    
    @After
    public void tearDown() {
        teardown();
    }
}
