I'm doing automation with Selenium - Page object Model & TestNG & Java. I have 2 testcases in 2 class files and i want to run all my tests in parallelReference Image I passed driver and test object to all my pages. When running my testng.xml with parallel="classes" two browser windows opened and only in one window, tests is running. The other window is closed. Eclipse showed me Null pointer exception. Answer: Later i understood that this is about usage of static in ExtentReport initialization. I corrected my code in reporter class.

Test Class-1:

public class CreateXCase extends SeleniumBase
{
    @BeforeTest(alwaysRun=true )
    public void setTestDetails()
    {
        author = System.getProperty("user.name"); 
        testcaseName="Verify that X case is successfully created";
        testcaseDec = "Create X Case";
        category="Regression";
    }


    @Test(priority=2,groups = {"Regression"})
    public  void createCaseWithNewParticipants() throws Exception
    {
        new LoginPage(driver, test).login().quickNavigation_CASE()
        .navigateToCreateCase().enterApplicantInformation()
        .navigateToCaseSection().createCase();
    }
}

Test Class-2:

public class CreateYcase extends SeleniumBase
{
    @BeforeTest(alwaysRun=true )
    public void setTestDetails()
    {
        author = System.getProperty("user.name"); 
        testcaseName="Verify that Y case is successfully created";
        testcaseDec = "Create Y Case";
        category="Regression";
    }

     @Test(priority=1,groups = {"Regression"})
     public  void createCaseWithNewParticipants() throws Exception
     {
        new LoginPage(driver,test).login().quickNavigation_CASE()
        .navigateToCreateCase().enterApplicantInformation()
        .navigateToCaseSection().createCase();
    }

SeleniumBase.java:

public class SeleniumBase extends Reporter implements Browser, Element 
{

    public static WebDriverWait wait;
    @BeforeMethod(alwaysRun=true )
    public void configureAndLaunch() throws IOException 
    {           
        driver = startApp(ReadPropertyFile.get("Browser"), ReadPropertyFile.get("URL"));
    }

    @Override
    @AfterMethod (alwaysRun=true )
    public void closeBrowser()
    {
        driver.quit();
    }


@Override
    public RemoteWebDriver startApp(String browser, String url) 
    {
        try 
        {
            if (browser.equalsIgnoreCase("chrome")) 
            {
                System.setProperty("webdriver.chrome.driver", "./drivers/chromedriver.exe");
                driver = new ChromeDriver();

            } 
            else if (browser.equalsIgnoreCase("firefox")) 
            {
                System.setProperty("webdriver.gecko.driver", "./drivers/geckodriver.exe");
                driver = new FirefoxDriver();

            } 
            else if (browser.equalsIgnoreCase("ie")) 
            {
                System.setProperty("webdriver.ie.driver", "./drivers/IEDriverServer.exe");
                driver = new InternetExplorerDriver();

            }
            driver.get(url);

            driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
            driver.manage().window().maximize();
            return driver;

        } 
        catch (Exception e) 
        {
            int a = e.toString().indexOf("Exception:");
            String str = e.toString().substring(0, a + 30);
            System.out.println(str + "Exception captured");

            System.err.println("The Browser Could not be Launched. Hence Failed");

        } 
        finally 
        {
            takeSnap();

        }
        return null;
    } 

Reporter.java:

public abstract class Reporter {

    public  RemoteWebDriver driver;

    public  ExtentHtmlReporter reporter;
    public  static ExtentReports extent;
    public  ExtentTest test;
    public String testcaseName, testcaseDec, author ;

What are the changes that you have already tried?Sebastian
@LeyonGudinho If we make static, it will not run in parallel. To be capable of running in parallel, we must keep it non-static.Arun
@Arun this is something to do with your ExtentReport variable and not webdriver so can you try making ExtentReports extent static. I will look into this tomorrow but meanwhile try my making report static.Leyon Gudinho
Making ExtentReports static should solve your issueLeyon Gudinho
If you still face the issue, use something that is popularly used. Extent tests using current local threads and ExtentReportsManager - github.com/swtestacademy/ExtentReportsExample Or github.com/vikas-thange/ExtentReports-TestNg-Integration Or github.com/djangofan/extent-reporting-exampleLeyon Gudinho

Making the ExtentReport variable 'extent' as static solved my issue. Eg: public static ExtentReports extent; I modified the code in my question also.

Since i have only one @Test in a class, parallel="methods" is of no use in my case.
