WebDriverManager for automatic driver management in Selenium Java - Build an Automation Script

Automate browser launch using WebDriverManager

Preconditions (2)

Step 1: Use WebDriverManager to setup ChromeDriver automatically

Step 2: Launch a new Chrome browser instance

Step 3: Navigate to 'https://example.com'

Step 4: Verify the page title is 'Example Domain'

Step 5: Close the browser

✅ Expected Result: Chrome browser opens, navigates to 'https://example.com', page title matches 'Example Domain', and browser closes without errors

Automation Requirements - Selenium WebDriver with WebDriverManager

Assertions Needed:

Assert that the page title equals 'Example Domain'

Best Practices:

Use WebDriverManager to manage driver binaries automatically

Use explicit waits if needed (not required here as page loads quickly)

Close the browser in a finally block or use try-with-resources

Use By locators only when interacting with page elements (not needed here)

Automated Solution

Selenium Java

import io.github.bonigarcia.wdm.WebDriverManager;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import static org.junit.jupiter.api.Assertions.assertEquals;

public class WebDriverManagerTest {
    public static void main(String[] args) {
        WebDriver driver = null;
        try {
            // Setup ChromeDriver automatically
            WebDriverManager.chromedriver().setup();

            // Launch Chrome browser
            driver = new ChromeDriver();

            // Navigate to example.com
            driver.get("https://example.com");

            // Verify page title
            String title = driver.getTitle();
            assertEquals("Example Domain", title);

            System.out.println("Test Passed: Page title is 'Example Domain'");
        } catch (AssertionError e) {
            System.out.println("Test Failed: " + e.getMessage());
        } finally {
            if (driver != null) {
                driver.quit();
            }
        }
    }
}

This code uses WebDriverManager to automatically download and setup the correct ChromeDriver binary for the current system. This removes the need to manually download or set system properties for the driver.

We create a ChromeDriver instance to launch the browser, then navigate to 'https://example.com'. We get the page title and assert it equals 'Example Domain' using JUnit's assertEquals method.

The try-finally block ensures the browser closes even if the assertion fails, preventing leftover browser processes.

This simple example shows how WebDriverManager simplifies driver management and how to verify page title with Selenium.

Common Mistakes - 4 Pitfalls

Manually downloading and setting driver path instead of using WebDriverManager

Not closing the browser after test execution

Using Thread.sleep() to wait for page load

Catching generic Exception instead of AssertionError for test assertions

Bonus Challenge

Now add data-driven testing to open multiple URLs and verify their titles
