import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class WebDriverTest {
    private WebDriver driver;

    @BeforeMethod
    public void setUp() {
        // Set up WebDriver instance
        System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
        driver = new ChromeDriver();
    }

    @Test
    public void testExample() {
        // Test logic using WebDriver
        driver.get("https://www.example.com");
