how to write junit test cases for Row Mapper class in spring
<p>Hi This is my Row Mapper class.</p>

<pre><code>public class UserRowMapper implements RowMapper&lt;UserData&gt; {

    @Override
    public UserData mapRow(ResultSet resultSet, int line) throws SQLException {
        UserData userData = new UserData();  
        try
        {
            userData.setUserID(resultSet.getString("User_ID"));
            userData.setUserName(resultSet.getString("User_Name"));  
            userData.setUserPassword(resultSet.getString("User_Password"));  
            userData.setUserRole(resultSet.getString("User_Role")); 
            userData.setUserStatus(resultSet.getString("User_Status")); 
            userData.setUserLogStatus(resultSet.getString("UserLog_Status")); 
            userData.setUserAccountName(resultSet.getString("User_AccountName")); 
            userData.setUserAccountID(resultSet.getString("User_AccountID")); 
            userData.setUserEmailID(resultSet.getString("User_EmailID")); 
            userData.setUserPasswordStatus(resultSet.getString("User_Password_ExpiryStatus")); 
            userData.setUserIDStatus(resultSet.getString("User_ID_Status")); 
            userData.setAcatTenantID(resultSet.getLong("acatTenant_ID")); 
            userData.setUserRoleCode(resultSet.getLong("User_Role_Code")); 
            userData.setUserSkillSetCode(resultSet.getLong("User_SkillSet_Code")); 
            userData.setUserAccountCode(resultSet.getLong("User_Account_Code")); 

            return userData;
        }
        catch (EmptyResultDataAccessException e)

<p>The above classes are my Row Mapper and Model class.i do not know how to write  junit test class for Row Mapper class .please any one guide me how to write junit test  for these classes.</p>

<p>Hi here is my Junit test code for above classes.</p>

<pre><code>public class UserRowMapperTest {
   UserRowMapper userRowMapper=null;

    @Before
    public void runBeforeEachTest(){
        userRowMapper= new UserRowMapper();

    }
    @After
    public void runAfterEachTest(){
        userRowMapper=null;
    }
    @Test
    public void testMapRow(){
        userRowMapper.mapRow(resultSet, line);
    }    
}
</code></pre>
