Можно ли наследовать тестовую аннотацию?

Я пытаюсь сделать авто-тест testng + selenium, но теперь я застрял.

У меня есть интерфейс, базовый класс и тестовый класс. Когда я запускаю testng, он не работает, потому что методы @beforeXXX и @afterXXX не вызываются, а NPE - thow. Консоль также не содержит мой выходной txt, просто сообщение об ошибке.

Можете ли вы помочь мне исправить это, изменив мой testng.xml или добавив некоторый вспомогательный класс?

Это мой интерфейс

public interface PrepareTestNG {

    @BeforeSuite
    public abstract void beforeSuit();

    @AfterSuite
    public abstract void afterSuit();

    @BeforeTest
    public abstract void beforeTest();

    @AfterTest
    public abstract void afterTest();

    @BeforeGroups
    public abstract void beforeGroups();

    @AfterGroups
    public abstract void afterGroups();

    @BeforeClass
    public abstract void beforeClass();

    @AfterClass
    public abstract void afterClass();

    @BeforeMethod
    public abstract void beforeMethod();

    @AfterMethod
    public abstract void afterMethod();
}

Это мой базовый класс

public abstract class BasicTest implements PrepareTestNG {
    protected WebDriver driver;

    public void beforeSuit() {
        System.out.println(">> suit ");
    }

    public void afterSuit() {
        System.out.println("<< suit");
    }

    public final void beforeTest() {
        driver = new HtmlUnitDriver(true);
        System.out.println(">> test");
    }

    public final void afterTest() {
        if (driver != null) {
            driver.quit();
        }
        driver = null;
        System.out.println("<< test");
    }

    @Test
    public abstract void verifyUserName();
}

И это мой тестовый класс

public class HomePageTest extends BasicTest {
    private Home homePage;

    @Test
    public void verifyTitle() {
        Assert.assertEquals("商城首页", homePage.getTitle());
        Assert.assertEquals(Url.HOME_PAGE, homePage.getUrl());
    }

    @Override
    public void beforeGroups() {
        System.out.println(">> group");
    }

    @Override
    public void afterGroups() {
        System.out.println("<< group");
    }

    @Override
    public void beforeClass() {
        driver.get(Url.HOME_PAGE);
        homePage = new Home(driver);
        System.out.println(">> class");
    }

    @Override
    public void afterClass() {
        homePage = null;
        System.out.println("<< class");
    }

    @Override
    public void beforeMethod() {
        System.out.println(">> method");
    }

    @Override
    public void afterMethod() {
        System.out.println("<< method");
    }

    @Override
    public void verifyUserName() {
        Assert.assertEquals("nobody", homePage.getUserName());
    }
}

Testng.xml настраивается следующим образом:

<suite name="suite">
    <test name="test" verbose="5">
        <packages>
            <package name="base">
                <exclude name="LoginPageTest" />
            </package>
        </packages>
    </test>
</suite>

и вывод consolo:
