Selenium WebDriver: My Setup for Automated Regression Testing

When I joined the FK IT Solution project, regression testing was taking 3+ hours per release cycle. Manual clicks through 50+ test cases, repeated every time a developer merged code. I proposed automating the critical path — and by the end, we cut that time in half.

My Stack

Selenium WebDriver (Java)
TestNG for test management and reporting
Maven for dependency management
ChromeDriver (headless for CI)

Project Structure

  test/
    java/
      base/
        BaseTest.java       ← WebDriver init/teardown
      pages/
        LoginPage.java      ← Page Object Model
        ProductPage.java

Page Object Model — LoginPage Example

public class LoginPage {
    private WebDriver driver;
@FindBy(id = "email") private WebElement emailField;
    @FindBy(id = "password") private WebElement passwordField;
    @FindBy(css = "button[type='submit']") private WebElement submitBtn;
    @FindBy(css = ".error-message") private WebElement errorMsg;
public LoginPage(WebDriver driver) {
        this.driver = driver;
        PageFactory.initElements(driver, this);
    }
public void login(String email, String password) {
        emailField.clear();
        emailField.sendKeys(email);
        passwordField.clear();
        passwordField.sendKeys(password);
        submitBtn.click();
    }
public String getErrorMessage() {
        return errorMsg.getText();
    }
}

Data-Driven Testing with TestNG

@DataProvider(name = "loginData")
public Object[][] loginData() {
    return new Object[][] {
        {"valid@email.com", "validPass123", true},
        {"invalid@email.com", "wrongPass", false},
        {"", "", false},
        {"sql@test.com", "' OR '1'='1", false},
    };
}
@Test(dataProvider = "loginData")
public void testLogin(String email, String pass, boolean shouldSucceed) {
    LoginPage loginPage = new LoginPage(driver);
    loginPage.login(email, pass);
if (shouldSucceed) {
        Assert.assertTrue(driver.getCurrentUrl().contains("/dashboard"));
    } else {
        Assert.assertFalse(loginPage.getErrorMessage().isEmpty());
    }
}

What Automated, What Didn't

Automated successfully:

Login/logout flows
Product search and filtering
Add to cart, update quantity
Coupon code application

Kept manual:

Visual/UI design checks
First-run exploratory testing
Payment gateway (sandbox limits)
