我的Java

public class LaunchApplication {
    private String LAUNCHAPPLICATION_STATUS=null;
    private String LAUNCHAPPLICATION_MESSAGE=null;


    @Test
    @Parameters({"RUN_USING_SG","BROWSER_CODE","URL","TITLE","PLATFORM","VERSION"})
    public void LAUNCHAPPLICATION(String RunUsingSG,String BrowserCode,String URL,String Title,String Platform,String Version) throws MalformedURLException
    {
        try
        {
            System.out.println(System.getProperty("user.dir"));
            DesiredCapabilities dc=new DesiredCapabilities();
            if(BrowserCode.equalsIgnoreCase("IE32"))
            {
                System.setProperty("webdriver.ie.driver",System.getProperty("user.dir")+"/AllDrivers/IEDriverServer_32bit_OS.exe");
                dc.setBrowserName("internet explorer");
                dc.setVersion(Version);
                Config.driver = new InternetExplorerDriver();

            }
            if(BrowserCode.equalsIgnoreCase("IE64"))
            { 
                System.setProperty("webdriver.ie.driver",System.getProperty("user.dir")+"/AllDrivers/IEDriverServer_64bit_OS.exe");
                dc.setBrowserName("internet explorer");
                dc.setVersion(Version);
                Config.driver = new InternetExplorerDriver();
            }
            if(BrowserCode.equalsIgnoreCase("FF"))
            { 
                FirefoxProfile firefoxProfile = new FirefoxProfile();
                dc.setBrowserName("firefox"); 
                dc.setVersion(Version);
                Config.driver=new FirefoxDriver();
            }
            if(RunUsingSG.equalsIgnoreCase("Y"))
            {
                Config.driver=new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),dc);

            }

            if(Platform.equalsIgnoreCase("WINDOWS"))
            {dc.setPlatform(org.openqa.selenium.Platform.WINDOWS);}
            Config.driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
            Config.driver.get(URL);
            Config.driver.manage().window().maximize();
            //perform final validation
            if(Config.driver.getTitle().toLowerCase().equalsIgnoreCase(Title))
            {
                LAUNCHAPPLICATION_STATUS="PASS";
                LAUNCHAPPLICATION_MESSAGE="EXPECTED BROWSER TITLE:"+Title+", ACTUAL BROWSER TITLE :"+Config.driver.getTitle()+", FOR THE URL:"+URL;
            }


        }//end of try

        catch(Exception generalException)
        {
            LAUNCHAPPLICATION_STATUS="FAIL";
            LAUNCHAPPLICATION_MESSAGE= "EXPECTED BROWSER TITLE:"+Title+", ACTUAL BROWSER TITLE :"+Config.driver.getTitle()+", FOR THE URL:"+URL+". DETAILS:Exception Occoured:"+generalException.getLocalizedMessage();

        }
    }

    //@BeforeTest
     //public void f1(ITestContext ctx) {

        //  if(ctx.getCurrentXmlTest().getParameter("EXECUTE").equals("NO"))
          //    {
            //  throw new SkipException("skiping this test case");
            //}


}

我在通过testng执行时在上面的代码中得到空指针异常的错误。我不知道为什么？当我通过junit执行它工作正常？所以任何帮助？我想这可能发生了因为我已经宣布LAUNCHAPPLICATION_STATUS = null;或任何其他问题。

TestNGContentHandler.endElement()中发生异常，这是一个非常强烈的暗示，问题出在XML文件中，而不是LaunchApplication类。在这种情况下，根据问题的最终结果，可能值得提交针对TestNG的错误以提供更清晰的错误消息。

尝试创建一个基本的“hello world”@Test，以便您可以验证TestNG（以及您的TestNG配置）的运行情况。如果失败，我们知道这是一个配置问题。否则，如果它有效，您可以将其缩小到特定的问题测试。
