I have created some test cases in Eclipse. But while running the testng.xml file it opens in a new browser every time. How do I run it in single browser? I am calling below for each test case, so it opens in a new browser each time.

@BeforeClass
    public static void setup()
    {           
        System.setProperty("webdriver.chrome.driver", "E:\\Selenium Jar\\chromedriver.exe");
        ChromeOptions options = new ChromeOptions();
        options.addArguments("--disable-extensions");
        driver = new ChromeDriver(options);
        driver.manage().window().maximize();            
    }
