public class test1 {
    public String baseUrl = "http://smsys.co/SQA_DEMO/";
    String driverPath ="C:\\Users\\Dell\\Desktop\\selenium\\chromedriver_win32\\chromedriver.exe";
    public WebDriver driver;

    @BeforeTest
    public void launchBrowser() {
        System.setProperty("webdriver.chrome.driver",driverPath);
        WebDriver driver = new ChromeDriver();
        driver.manage().window().maximize();
        driver.get(baseUrl);
