Thanks, that give me and Idea. The solution is this:

@BeforeClass
public static void setUpBeforeClass() throws Exception {
        String[] args = new String[0];
        if(QCoreApplication.instance() ==null){
            QCoreApplication.initialize(args);
            QJdbc.initialize();
           
            try {
                Class.forName("org.h2.Driver");
            }
            catch (Exception ex) {
                System.err.println(ex);
            }
        }
       
        QSqlDatabase db = QSqlDatabase.addDatabase(QJdbc.ID);
        db.setDatabaseName("jdbc:h2:databases/clientes/clientes");
        db.setUserName("sa");
        db.setPassword("");
       
        if (db.open()) {
            System.out.println("Conexión realizada!");
        } else {
            System.err.println("Conexión fallida!");
            System.err.println(db.lastError().text());
        }
        return;
    }

    @AfterClass
    public static void tearDownAfterClass() throws Exception {
        QSqlDatabase.database().close();
    }

This is the only way that I found the fix the problem, because Junit4 
doesn´t support beforeSuit or afterSuite  test Tags or anything similar.

Thanks for the help.
