Spring: "NoSuchBeanDefinitionException: No bean named 'dataSource' is defined" when testing

I have been trying to test the DAO layer of an application, however I keep getting this error.

Here is the Test class

RegionDAOTest.java

import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.teamw.ibt.dao.impl.RegionDAOImpl;
import com.teamw.ibt.model.Region;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(locations = "classpath:app-context.xml")
public class RegionDAOTest extends AbstractDAOTest {

 @Autowired
 private JdbcTemplate jdbcTemplate;
 private RegionDAOImpl regionDAOImpl;

 @Before
 public void setUp(){
     regionDAOImpl = new RegionDAOImpl();
     regionDAOImpl.setJdbcTemplate(jdbcTemplate);
 }

 @After
 public void tearDown(){
 }

 @Test
    public void testContext() {
        assertNotNull(regionDAOImpl);
    }

 @Test
 public void FindByCodeTest() {
    Region region = regionDAOImpl.findByCode("1");
    assertEquals('1', region.getCode());
    assertEquals("Region 1", region.getName());
 }
}

RegionDAOImpl.java

@Repository
public class RegionDAOImpl implements RegionDAO {

@Autowired
private JdbcTemplate jdbcTemplate;

public RegionDAOImpl() {

}

@Autowired
public RegionDAOImpl(JdbcTemplate jdbcTemplate) {
    this.jdbcTemplate = jdbcTemplate;
}

@Autowired
public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
    this.jdbcTemplate = jdbcTemplate;
}


public void insert(Region region) {
    String query = "INSERT INTO IBT.REGION (code, name) VALUES ('" + region.getCode() + "','" + region.getName() + "');";
    jdbcTemplate.update(query);
}

public Region findByCode(String code) {
    String query = "SELECT * FROM IBT.REGION WHERE CODE = '" + code + "';";
    return jdbcTemplate.query(query, new ResultSetExtractor<Region>() {
        @Override
        public Region extractData(ResultSet rs) throws SQLException, DataAccessException {
            if (rs.next()) {
                return new Region(
                    rs.getString("code"),
                    rs.getString("name")
                );
            }

            return null;
        }
    });
}
}

app-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://ift.tt/GArMu6"
  xmlns:xsi="http://ift.tt/ra1lAU" 
  xsi:schemaLocation="http://ift.tt/GArMu6
  http://ift.tt/QEDs1e ">

<!-- Initialization for data source -->
 <bean id="dataSource" 
   class="org.springframework.jdbc.datasource.DriverManagerDataSource">
   <property name="driverClassName" value="org.h2.Driver"/>
   <property name="url" value="jdbc:h2:mem"/>
   <property name="username" value="SA"/>
   <property name="password" value="test"/>
 </bean>

 <bean id="JdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="dataSource"></property>
 </bean>

<bean id="regionDAOImpl" name="regionDAOImpl" class="com.teamw.ibt.dao.impl.RegionDAOImpl">
  <constructor-arg ref="jdbcTemplate"/>
</bean>
</beans>

As far as I know, I have set up everything correctly, but for some reason it says dataSource is not defined.
