can't start test dbunit+h2 problem detected: org.dbunit.dataset.NoSuchTableException

Hello, everybody!
At the beginning, sorry for my mistakes in English that i can make in future.
This is my first experience to participate in forums in english.

I try test my DAO layer in the application with dbunit and local database h2.
Here is my dataset.xml

Code :

---

<?xml version='1.0' encoding='UTF-8'?>
<dataset>
    <Employer idEmployer="10" company_name="JetBrains" phone="237643627" email="jetBrains@soft.com"/>
    <Vacancy idVacancy="8" employer_id="10" vacancy_name="java-programmer" vacancy_status="free" last_date="1990-09-24" salary="10000"/>
</dataset>

---

And my test class:

Code :

---

package testDaoLayer;
 
import org.dbunit.DBTestCase;
import org.dbunit.dataset.IDataSet;
import org.dbunit.dataset.ITable;
import org.dbunit.dataset.xml.FlatXmlDataSetBuilder;
import org.dbunit.operation.DatabaseOperation;
 
import java.io.File;
import java.io.FileInputStream;
import java.sql.SQLException;
 
import static org.dbunit.PropertiesBasedJdbcDatabaseTester.*;
import static org.junit.Assert.*;
 
public class TestDao extends DBTestCase{
 
    private IDataSet loadedDataSet=null;
 
    public TestDao() throws SQLException{
        super();
        System.setProperty(DBUNIT_DRIVER_CLASS, "org.h2.Driver");
        System.setProperty(DBUNIT_CONNECTION_URL, "jdbc:h2:~/test.public");
        System.setProperty(DBUNIT_USERNAME, "sa");
        System.setProperty(DBUNIT_PASSWORD, "root");
    }
 
    @Override
    protected IDataSet getDataSet() throws Exception {
        loadedDataSet = new FlatXmlDataSetBuilder().build(new FileInputStream("dataset.xml"));
        return loadedDataSet;
    }
 
    protected DatabaseOperation getSetUpOperation(){
        return DatabaseOperation.REFRESH;//CLEAN_INSERT;
    }
 
    protected DatabaseOperation getTearDownOperation() {
        return DatabaseOperation.NONE;
    }
 
    public void testCheckingLoadedData() throws Exception {
        // Execute the tested code that modify the database here
        //        ...
 
        // Fetch database data after executing your code
        IDataSet databaseDataSet = getDataSet();//getConnection().createDataSet();
        ITable actualTable = databaseDataSet.getTable("Employer");
 
        // Load expected data from an XML dataset
        IDataSet expectedDataSet = new FlatXmlDataSetBuilder().build(new File("dataset.xml"));
        ITable expectedTable = expectedDataSet.getTable("Employer");
 
        // Assert actual database table match expected table
        assertEquals(expectedTable, actualTable);
 
 
//        assertNotNull(loadedDataSet);
//        int rowCount = loadedDataSet.getTable("Employer").getRowCount();
    }
}

But when I run this test I get the exception:
