Mockito 模拟如何返回在 void 方法中修改的输入参数

如何解决Mockito 模拟如何返回在 void 方法中修改的输入参数

我正在尝试编写一个方法的测试并模拟在该方法中调用的调用。

我在这里尝试了 2 种方法，第一种是 doNothing(..) 用于设置一个输入参数的中间调用，这是有效的。

我想尝试的第二种方法是它是否可以返回/设置该输入 arg 但由于它是一个 void 方法，我对如何这样做有点困惑。我添加了一些试验作为评论，但希望得到一些教导和答案。

另外，想知道一种方法是否比其他方法更好。

我要测试的方法是populateProfile(..)

public abstract class BaseA {

    @Inject
    protected BaseUtils baseUtils;

    protected void populateProfile(Person person,final Profile profile) {
        if (profile == null) {
            return;
        }
        // THIS CALL
        baseUtils.populateAddressHelper(person,profile);

        Phone phone = profile.getPrimaryPhone() != null ? profile.getPrimaryPhone() : profile.getSecondaryPhone();
        if (phone != null) {
            person.setPhone(phone.getNumber());
        }
        Email email = profile.getEmail();
        if (email != null) {
            person.setEmail(email.getAddress());
        }
    }
}

Child class

public class Child extends BaseA {

...
}

BaseUtils class where the intermediary calls take place

@Component
class BaseUtils {
public void populateAddressHelper(Person person,final Profile profile) {
        Address profileAddress = profile.getAddress();
        if (profileAddress != null) {

            String streetAddress = null;
            if (profileAddress.getAddressLine1() != null) {
                streetAddress = profileAddress.getAddressLine1();
                if (profileAddress.getAddressLine2() != null) {
                    streetAddress += profileAddress.getAddressLine2();
                }
            }
            SMAddress mainAddress = populateMainAddress(streetAddress,profileAddress.getCity(),profileAddress.getState(),profileAddress.getPostalCode(),profileAddress.getCountry());

            person.setMainAddress(mainAddress);
        }
    }

    public SMAddress populateMainAddress(final String streetAddress,final String city,final String state,final String postalCode,final String countryCode) {

        SMAddress mainAddress = new SMAddress();
        mainAddress.setAddress(streetAddress);

        if (city != null) {
            mainAddress.setSuburb(city);
        }
        if (state != null) {
            mainAddress.setState(state);
        }
        if (postalCode != null) {
            mainAddress.setPostcode(postalCode);
        }
        if (countryCode != null && !countryCode.isEmpty()) {
            CountryCodeEnum codeEnum = CountryCodeEnum.valueOf(countryCode);
            mainAddress.setCountry(codeEnum.getName());
        }
        return mainAddress;
    }
}

Test for populateProfile(..)

@RunWith(MockitoJUnitRunner.class)
public class ChildTest extends BaseTest {

    @Mock
    private BaseUtils baseUtils;

    @InjectMocks
    Child child = new Child();

    @Before
    public void init() {
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void populateProfileTest() {
        Person person = new Person();
        UserData userData = createUserData();
        Profile profile = userData.getBusinessProfile();

//        SMAddress mainAddress = mock(SMAddress.class);
//        doReturn(mainAddress).when(baseUtils).populateMainAddress(anyString(),anyString(),anyString());

        doNothing().when(baseUtils).populateMainAddressHelper(person,profile);

        child.populateProfile(person,profile);
        //assertEquals(profile.getAddress().getCity(),person.getMainAddress().getSuburb());
        assertEquals(profile.getEmail().getAddress(),person.getEmail());
        assertEquals(profile.getPrimaryPhone().getNumber(),person.getPhone());
        //assertNotNull(person.getMainAddress());
        verify(baseUtils,times(1)).populateMainAddressHelper(person,profile);
        //verify(baseUtils).populateMainAddress(anyString(),anyString());
    }
