創建EntityManager + Junit + HSQLDB的問題

我收到奇怪的問題。我正在嘗試進行集成測試，但實體管理器創建器無法正常工作。創建EntityManager + Junit + HSQLDB的問題

public class RepositoryTest { 

    protected static EntityManagerFactory factory; 
    protected static EntityManager em; 

    @BeforeClass 
    public static void setUpPersistence() { 
     factory = Persistence.createEntityManagerFactory("db-test"); 
     em = factory.createEntityManager(); 
     em.getTransaction().begin(); 
    } 

    @AfterClass 
    public static void tearDown() { 
     em.getTransaction().commit(); 
     em.close(); 
     factory.close(); 
    } 
} 

public class GrupoRepositoryTest extends RepositoryTest { 

    private GrupoRepository repository; 

    @Before 
    public void setUp() { 

     this.repository = new GrupoRepositoryImpl(em); 
    } 
} 


@Entity 
@Table(name = "grupos") 
public class Grupo implements Model{ 

    @Id 
    @GeneratedValue 
    @Column(name = "id") 
    private Long id; 

    @Column(name = "nome") 
    private String nome; 

    public Grupo() { 
    } 

    public Grupo(Long id, String nome) { 
     this.id = id; 
     this.nome = nome; 
    } 

    //gets and sets 
}

的日誌出現在這裏：

STOPS HERE!

，並給出了異常Caused by: java.sql.SQLException: No suitable driver found for jdbc: hsqldb: mem: db-test。

爲了解決這個例外，我做到了在setUpPersistence（）（甚至不知道它是否是最好的解決方案）：

try { 
    Class.forName ("org.hsqldb.jdbcDriver"); 
    connection = DriverManager.getConnection ("jdbc: hsqldb: mem: db-test", "sa", ""); 
} Catch (Exception ex) { 
    ex.printStackTrace(); 
}

其後，當道路試驗給出了錯誤：
