在Maven中運行TestNG測試失敗，因為拆卸方法

Question

我在Maven上運行testNG測試時遇到問題，問題是我認為我的測試既沒有並行執行也不以正確的順序執行，我之所以這樣說是因為每次我執行call mvn test來使用我的測試時，得到錯誤：

Running com.pruebas.seleniumGridTestNG.dataDrivenParallelXML.TestLanzadorIdealistaTestNG
Configuring TestNG with: org.apache.maven.surefire.testng.conf.TestNG652Configurator@4ba33d48
Tests run: 3, Failures: 1, Errors: 0, Skipped: 2, Time elapsed: 0.484 sec <<< FAILURE!
tearDown(com.pruebas.seleniumGridTestNG.dataDrivenParallelXML.TestLanzadorIdealistaTestNG)  Time elapsed: 0.348 sec  <<< FAILURE!
java.lang.NullPointerException
    at com.pruebas.seleniumGridTestNG.dataDrivenParallelXML.TestLanzadorIdealistaTestNG.tearDown(TestLanzadorIdealistaTestNG.java:118)

顯然，我正在嘗試在測試類上執行@AfterClass方法，這就是為什么我得到NULL異常的原因。

public class TestLanzadorIdealistaTestNG {

    private RemoteWebDriver driver;
    @Parameters({ "browser","platformBrowser","versionBrowser","URL_NODE_HUB" })

    @Test
    public void generoDriver(String browser, String platformBrowser,String versionBrowser,String URL_NODE_HUB) throws InterruptedException, MalformedURLException{

        DesiredCapabilities cap = null;
        Platform plataform = null;


        /**
         * - INICIO - Controlamos la plataforma en la que se va a lanzar el test
         */

        if (platformBrowser.equals("MAC")){
            plataform = Platform.MAC;
        }

        if (platformBrowser.equals("WINDOWS"))
        {
            plataform  = Platform.WINDOWS;
        }

        if (platformBrowser.equals("LINUX")){
            plataform = Platform.LINUX;
        }

        if (platformBrowser.equals("")) // caso por defecto
        {
            plataform = Platform.ANY;
        }
        /**
         * -FIN- Controlamos la plataforma en la que se va a lanzar el test
         */


        /**
         * - INICIO - logica para lanzar segun version del navegador
         */

        if (browser.equals("firefox"))
        {
            cap = DesiredCapabilities.firefox();
            cap.setPlatform(plataform);
            cap.setBrowserName(browser);
            cap.setVersion(versionBrowser);
        }else if (browser.equals("chrome")) {
            cap = DesiredCapabilities.chrome();
            cap.setPlatform(plataform);
            cap.setBrowserName(browser);
            cap.setVersion(versionBrowser);
        } else if(browser.equals("internet explorer")){
            cap = DesiredCapabilities.internetExplorer();
            cap.setPlatform(plataform);
            cap.setBrowserName(browser);
            cap.setVersion(versionBrowser);
        } else if (browser.equals("safari")){
            cap = DesiredCapabilities.safari();
            cap.setPlatform(plataform);
            cap.setBrowserName(browser);
            /**
             * - INICIO - Controlamos el caso en que no pusimos version de navegador alguna
             */

            if (versionBrowser.equals("")){
                cap.setVersion("");
            }
            else
            {
                cap.setVersion(versionBrowser);
            }
            /**
             * - FIN - Controlamos el caso en que no pusimos version de navegador alguna
             */

        } 

        /**
         * - FIN - logica para lanzar segun version del navegador
         */
        cap.setJavascriptEnabled(true); 
        driver = new RemoteWebDriver(new URL(URL_NODE_HUB), cap);

    }

/**

 * habitacion y vacacional es desactivado y no posible de seleccionar en el area

@Test (dependsOnMethods={"generoDriver"})
    public void ComprarDeactivateHabitacionVacacional() throws InterruptedException, MalformedURLException{
        com.pruebas.seleniumGridTestNG.dataDrivenParallelXML.ManejadorPrograma manejador = new com.pruebas.seleniumGridTestNG.dataDrivenParallelXML.ManejadorPrograma(driver);
        manejador.logicaPrograma();

}

@AfterTest
public void tearDown(){
        driver.quit();
}

這是我的pom.xml文件：
