UnitTest SpringBatch FieldSetMapper

Question

я получил следующий заказ FieldSetMapper

import org.springframework.batch.item.file.mapping.FieldSetMapper; 
import org.springframework.batch.item.file.transform.FieldSet; 
import org.springframework.validation.BindException; 

import de.BasicProperty; 

public class PersonItemFieldSetMapper implements FieldSetMapper<PersonItem> { 

    @Override 
    public PersonItem mapFieldSet(final FieldSet fieldSet) throws BindException { 
     PersonItem person = new PersonItem(); 
     person.setLastName(fieldSet.readString(BasicProperty.BASICPROP_LASTNAME)); 
     person.setFirstName(fieldSet.readString(BasicProperty.BASICPROP_FIRSTNAME)); 
     person.setEmployeeType(fieldSet.readString("EmployeeType")); 
     person.setFormOfAdress(fieldSet.readString(BasicProperty.BASICPROP_FORMOFADDRESS)); 
     person.setEMail(fieldSet.readString(BasicProperty.BASICPROP_EMAIL)); 
     person.setUpn(fieldSet.readString(BasicProperty.BASICPROP_UPN)); 
     person.setWorkforceId(fieldSet.readString(BasicProperty.BASICPROP_WORKFORCE_ID)); 
     person.setInstitute(fieldSet.readString(BasicProperty.BASICPROP_INSTITUTE)); 
     person.setPhoto(fieldSet.readString(BasicProperty.BASICPROP_PHOTO)); 

     return person; 
    } 

} 

В настоящее время я пытаюсь написать юнит-тест для этого преобразователя. Первый вопрос: Это разумно? Второй вопрос: Как я могу это достичь?

Answer 1

Да, вы можете написать тестовые случаи для mapFieldSet()

You can always write such test cases to make sure your mapping are good! 
// Using EasyMock to mock FieldSet 
@Test 
public void mapFieldSetTest() 
{ 
    FieldSet mockFieldSet = EasyMock.createMock(FieldSet.class); 

    EasyMock.expect(mockFieldSet.readString("LNAME")).andReturn("Doe"); 
    EasyMock.expect(mockFieldSet.readString("FNAME")).andReturn("John"); 
    EasyMock.expect(mockFieldSet.readString("ETYPE")).andReturn("PART-TIME"); 
    EasyMock.expect(mockFieldSet.readString("FADDRESS")).andReturn("191, Santa Clara"); 
    EasyMock.expect(mockFieldSet.readString("EMAIL")).andReturn("john.Doe@fb.com"); 
    EasyMock.expect(mockFieldSet.readString("UPN")).andReturn("1111111111"); 
    EasyMock.expect(mockFieldSet.readString("WFID")).andReturn("22222222"); 
    EasyMock.expect(mockFieldSet.readString("INS")).andReturn("CA University College"); 
    EasyMock.expect(mockFieldSet.readString("PIC")).andReturn("c:\\john_doe.jpg"); 

    EasyMock.replay(mockFieldSet); 

    // call the method under test 
    PersonItem actual = fieldSetMapper.mapFieldSet(mockFieldSet); 

    EasyMock.verify(mockFieldSet); 

    // assert actual data by getters.. 
}
