- Collections
- File handling
Basic Java Example
public class LoginTest {
public static void main(String[] args) {
String username = "admin";
String password = "admin123";
if (username.equals("admin") && password.equals("admin123")) {
System.out.println("Login credentials are valid");
} else {
System.out.println("Invalid credentials");
}
}
}
9. Object-Oriented Programming for Selenium
Object-Oriented Programming concepts are important when developing maintainable Selenium automation frameworks.
- Class
- Object
- Inheritance
- Polymorphism
- Encapsulation
- Abstraction
These concepts are especially useful when implementing Page Object Model, reusable components, base classes, utilities, and framework architecture.
10. Selenium Environment Setup
A Selenium automation environment generally consists of Java, an IDE, Selenium libraries, a browser, browser automation support, and a build or dependency management tool such as Maven.
Typical Project Structure
SeleniumProject
│
├── src
│ ├── test
│ └── main
│
├── pom.xml
├── testng.xml
└── README.md
11. First Selenium Automation Script
A basic Selenium program creates a WebDriver instance, opens a web page, performs browser operations, and finally closes the browser.
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class FirstSeleniumTest {
public static void main(String[] args) {
WebDriver driver = new ChromeDriver();
driver.get("https://www.google.com");
System.out.println(driver.getTitle());
driver.quit();
}
}
12. Selenium WebDriver Browser Automation
WebDriver provides commands for controlling browsers programmatically.
Common WebDriver Operations
driver.get("https://example.com");
driver.getTitle();
driver.getCurrentUrl();
driver.navigate().back();
driver.navigate().forward();
driver.navigate().refresh();
driver.quit();
13. Locating Web Elements
Locators allow Selenium to identify elements on a web page.
Common Selenium Locators
| Locator | Example |
| ID | By.id("username") |
| Name | By.name("email") |
| Class Name | By.className("login-button") |
| Tag Name | By.tagName("input") |
| Link Text | By.linkText("Login") |
| Partial Link Text | By.partialLinkText("Log") |
| CSS Selector | By.cssSelector("#username") |
| XPath | By.xpath("//input[@id='username']") |
14. Working with WebElements
Once an element has been located, Selenium provides methods for interacting with it.
WebElement username = driver.findElement(By.id("username"));
username.clear();
username.sendKeys("admin");
username.click();
Common WebElement Methods
- click()
- sendKeys()
- clear()
- getText()
- getAttribute()
- isDisplayed()
- isEnabled()
- isSelected()
15. Browser Automation with Chrome, Firefox and Edge
The course curriculum includes browser automation using Chrome, Firefox, and Edge.
WebDriver chromeDriver = new ChromeDriver();
WebDriver firefoxDriver = new FirefoxDriver();
WebDriver edgeDriver = new EdgeDriver();
16. Handling Forms
Selenium can automate common web form interactions such as entering text, selecting options, clicking buttons, checking checkboxes, and submitting forms.
driver.findElement(By.id("name")).sendKeys("John");
driver.findElement(By.id("email")).sendKeys("[email protected]");
driver.findElement(By.id("submit")).click();
17. Handling Alerts and Popups
Selenium provides the Alert interface for interacting with JavaScript alerts.
Alert alert = driver.switchTo().alert();
System.out.println(alert.getText());
alert.accept();
Common Alert Operations
- accept()
- dismiss()
- getText()
- sendKeys()
18. Handling Frames and Iframes
Frames and iframes contain separate document contexts. Selenium must switch to the frame before interacting with elements inside it.
driver.switchTo().frame("paymentFrame");
driver.findElement(By.id("cardNumber")).sendKeys("123456");
driver.switchTo().defaultContent();
19. Multiple Windows and Tabs
Selenium supports handling multiple browser windows and tabs using window handles.
String parentWindow = driver.getWindowHandle();
Set windows = driver.getWindowHandles();
for (String window : windows) {
if (!window.equals(parentWindow)) {
driver.switchTo().window(window);
}
}
20. Mouse and Keyboard Actions
The Actions class is used for advanced user interactions such as mouse hover, drag and drop, right-click, double-click, and keyboard interactions.
Actions actions = new Actions(driver);
actions.moveToElement(element).perform();
actions.doubleClick(element).perform();
actions.contextClick(element).perform();
actions.dragAndDrop(source, target).perform();
21. File Upload and Download Handling
Selenium can automate file upload controls when the web page exposes a file input element.
WebElement upload = driver.findElement(By.id("fileUpload"));
upload.sendKeys("C:\\files\\document.pdf");
File download validation generally requires browser configuration, filesystem validation, or additional Java utilities depending on the application and test requirements.
22. Selenium Waits and Synchronization
Modern web applications often load elements dynamically. Selenium automation therefore needs synchronization strategies.
Types of Waits
- Implicit Wait
- Explicit Wait
- Fluent Wait
Explicit Wait Example
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
WebElement loginButton = wait.until(
ExpectedConditions.elementToBeClickable(By.id("login"))
);
loginButton.click();
23. Dynamic Web Elements
Dynamic elements may change their attributes, location, availability, or content during execution. Stable locators and proper synchronization are important when automating such applications.
- Use reliable locators
- Avoid unnecessary hard-coded delays
- Use explicit waits for important conditions
- Use relative XPath or CSS selectors where appropriate
- Design reusable synchronization utilities
24. TestNG Framework
TestNG is a testing framework commonly used with Selenium for organizing, executing, grouping, parameterizing, and validating automated test cases.
Common TestNG Features
- Annotations
- Assertions
- Test execution
- Data-driven testing
- Parallel execution
- Grouping
- Test configuration
Basic TestNG Example
import org.testng.annotations.Test;
public class LoginTest {
@Test
public void verifyLogin() {
System.out.println("Login test executed");
}
}
25. TestNG Annotations
| Annotation | Purpose |
| @BeforeSuite | Runs before the complete test suite |
| @BeforeTest | Runs before configured test execution |
| @BeforeClass | Runs before test methods in a class |
| @BeforeMethod | Runs before each test method |
| @Test | Defines a test method |
| @AfterMethod | Runs after each test method |
| @AfterClass | Runs after test methods in a class |
| @AfterSuite | Runs after the complete test suite |
26. Assertions and Validations
Assertions verify whether actual application behavior matches the expected result.
Assert.assertEquals(
driver.getTitle(),
"Expected Title"
);
27. Data-Driven Testing
Data-driven testing separates test logic from test data. The same automation test can then be executed with multiple input values.
Possible Data Sources
- Excel
- CSV
- Properties files
- Database
- JSON
- TestNG DataProvider
TestNG DataProvider Example
@DataProvider(name = "loginData")
public Object[][] loginData() {
return new Object[][] {
{"admin", "admin123"},
{"user1", "user123"},
{"tester", "test123"}
};
}
@Test(dataProvider = "loginData")
public void loginTest(String username, String password) {
System.out.println(username + " - " + password);
}
28. Page Object Model
Page Object Model, commonly called POM, is an automation design pattern in which application pages are represented by Java classes. Locators and page interactions are maintained inside page classes, while test classes focus on test scenarios.
Example Page Object
public class LoginPage {
WebDriver driver;
By username = By.id("username");
By password = By.id("password");
By loginButton = By.id("login");
public LoginPage(WebDriver driver) {
this.driver = driver;
}
public void enterUsername(String value) {
driver.findElement(username).sendKeys(value);
}
public void enterPassword(String value) {
driver.findElement(password).sendKeys(value);
}
public void clickLogin() {
driver.findElement(loginButton).click();
}
}
29. Advantages of Page Object Model
- Improves code organization
- Reduces duplicate locators
- Makes maintenance easier
- Encourages reusable page actions
- Separates test logic from page implementation
- Supports scalable automation frameworks
30. Automation Framework Concepts
The course curriculum includes framework concepts, Page Object Model, data-driven framework, keyword-driven framework, hybrid framework design, and reusable test architecture.
Common Framework Types
| Framework | Description |
| Data-Driven | Separates test data from test logic |
| Keyword-Driven | Uses keywords to represent automation actions |
| Hybrid | Combines multiple framework approaches |
| Page Object Model | Organizes application pages into reusable classes |
31. Maven and Dependency Management
Maven can be used to manage project dependencies, build the project, and execute automation tests.
Typical Maven Dependency Categories
- Selenium WebDriver
- TestNG
- Apache POI
- Reporting libraries
- Logging libraries
32. Test Data with Excel and CSV

33. Parameterization
Parameterization allows the same test scenario to execute with different input values.
Username | Password
---------|---------
admin | admin123
user1 | user123
tester | test123
34. Test Reporting
Automation frameworks can generate execution reports that help teams understand passed tests, failed tests, skipped tests, execution time, and failure information.
The course curriculum mentions reporting tools such as ExtentReports and Allure.
35. Logging with Log4j
Logging provides information about the execution flow of an automation test. Logs can help identify where a test failed and what operations were executed before the failure.

↓
Browser Launched
↓
Application Opened
↓
Login Executed
↓
Validation Performed
↓

36. Debugging Failed Test Cases
Debugging is an important part of automation development. When a test fails, the tester should identify whether the failure is caused by the application, locator, synchronization, test data, browser, environment, or automation code.
Debugging Checklist
- Check the exception message
- Verify the locator
- Check page loading behavior
- Verify test data
- Check synchronization
- Review screenshots
- Review execution logs
- Reproduce the issue manually when required
37. Selenium Grid
Selenium Grid allows Selenium tests to execute remotely and can support parallel execution across different browser and environment combinations.
Grid Execution Concept
Test Suite
|
+---- Chrome
|
+---- Firefox
|
+---- Edge
|
+---- Different Operating Systems
38. Cross-Browser Testing
Cross-browser testing validates web application behavior across supported browsers.
| Browser | Example |
| Chrome | ChromeDriver |
| Firefox | FirefoxDriver |
| Edge | EdgeDriver |
39. Parallel Test Execution
Parallel execution allows multiple independent tests or browser sessions to execute concurrently. It can be useful for reducing total suite execution time when the environment and test architecture support safe parallel execution.
40. Remote Execution
Remote execution allows tests to run on a remote machine or Selenium Grid environment rather than directly on the local machine.

43. Headless Browser Testing
Headless testing runs browser automation without displaying the normal browser user interface. It can be useful in CI/CD environments and automated execution servers.
Chrome Headless Example
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless=new");
WebDriver driver = new ChromeDriver(options);
44. Browser Capabilities and Profiles
Browser options and capabilities allow testers to configure browser behavior before creating the WebDriver session.
ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized");
WebDriver driver = new ChromeDriver(options);
45. Screenshot Capture
Screenshots can be captured when tests fail or when visual evidence is required.
TakesScreenshot screenshot =
(TakesScreenshot) driver;
File source =
screenshot.getScreenshotAs(OutputType.FILE);
46. Video Capture
Video capture may be integrated through the surrounding test infrastructure or external tooling when execution evidence is required. The course curriculum includes screenshot and video capture as advanced automation topics.
47. API Testing Integration
