Getting IllegalArgumentException while running test with Spring

I am trying to do test as follow:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { 
  "classpath:test-context.xml"
})
public class EventTest {

  @Autowired private DataSource dataSource;
  JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);

  @Test
  public void testEvent(){
    String sql = "select * from event";
    List<Map<String, Object>> resultSet = jdbcTemplate.queryForList(sql);
    System.out.println(resultSet);
  }
}

In test-context.xml I have

<jdbc:embedded-database id="datasource">
    <jdbc:script  location="classpath:schema.sql" />
    <jdbc:script  location="classpath:data.sql" />
</jdbc:embedded-database>

Still I am getting exception

java.lang.IllegalArgumentException: Property 'dataSource' is required
  at org.springframework.jdbc.support.JdbcAccessor.afterPropertiesSet(JdbcAccessor.java:134)
  at org.springframework.jdbc.core.JdbcTemplate.<init>(JdbcTemplate.java:165)

Any suggestion?
