Mockito说论点并不相同，但它们是相同的

Question

这是我要测试的方法：

public class SelectionVariantUniqueConstraintValidatorImpl implements UniqueConstraintValidator {
    private SessionFactory sessionFactory;
    @Override
    public List<Criteria> buildValidationCriteria(Object entity, Serializable id, String[] propertyNames) {
        final SelectionVariant selectionVariant = (SelectionVariant) entity;
        final Session session = sessionFactory.getCurrentSession();
        final Criteria criteria = session.createCriteria(SelectionVariant.class);
        criteria.add(Restrictions.eq("client", selectionVariant.getClient()));
        criteria.add(Restrictions.eq("variant.variantName", selectionVariant.getVariant().getVariantName()));
        return new ArrayList<Criteria>(Arrays.asList(criteria));
    }
    @Required
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
}

这是我的测试：

@RunWith(MockitoJUnitRunner.class)
public class SelectionVariantUniqueConstraintValidatorImplTest {
    SelectionVariantUniqueConstraintValidatorImpl selectionVariantUniqueConstraintValidator
            = new SelectionVariantUniqueConstraintValidatorImpl();
    @Mock
    private SessionFactory sessionFactory;
    @Mock
    private Session session;
    @Mock
    private Criteria criteria;
    @Before
    public void setUp() throws Exception {
        selectionVariantUniqueConstraintValidator.setSessionFactory(sessionFactory);
    }
    @Test
    public void testBuildValidationCriteria() throws Exception {
        Mockito.when(sessionFactory.getCurrentSession()).thenReturn(session);
        Mockito.when(session.createCriteria(SelectionVariant.class)).thenReturn(criteria);
        SelectionVariant selectionVariant = new SelectionVariant();
        Client client = new ClientBuilder().businessKey("HPD").description("desc").version(0).id(1L).build();
        selectionVariant.setClient(client);
        selectionVariantUniqueConstraintValidator.buildValidationCriteria(selectionVariant, null, null);
        Mockito.verify(criteria,Mockito.atLeastOnce()).add(Restrictions.eq("client", selectionVariant.getClient()));
    }
}

这就是我在控制台中看到的：

Argument(s) are different! Wanted:
criteria.add(
    client=Client{id=1, businessKey='HPD', description='desc', version=0}
);
-> at com.innflow.ebtam.dao.hibernate.variant.SelectionVariantUniqueConstraintValidatorImplTest.testBuildValidationCriteria(SelectionVariantUniqueConstraintValidatorImplTest.java:48)
Actual invocation has different arguments:
criteria.add(
    client=Client{id=1, businessKey='HPD', description='desc', version=0}
);
-> at com.innflow.ebtam.dao.hibernate.variant.SelectionVariantUniqueConstraintValidatorImpl.buildValidationCriteria(SelectionVariantUniqueConstraintValidatorImpl.java:36)

我缺少什么？

编辑：

等于client.java中的方法如下：

@Override
public boolean equals(Object o) {
    if (this == o) return true;
    if (o == null || (getClass() != o.getClass() && !(o instanceof Client))) return false;
    Client client = (Client) o;
    if (businessKey != null ? !businessKey.equals(client.getBusinessKey()) : client.getBusinessKey() != null)
        return false;
    return true;
}

编辑：

client.java中的hashcode方法：

@Override
public int hashCode() {
    return businessKey != null ? businessKey.hashCode() : 0;
}

编辑：

这使得测试工作：

Mockito.verify(criteria,Mockito.atLeastOnce()).add(Restrictions.eq("client", Mockito.any(Client.class)));

Answer 1

criteria.add的参数不是 Client，而是限制的返回值。eq，一种简单的表达。

SimpleExpression从 Object继承了其.quals-hethod，因此，由于您在测试中构造一个新的参数，即使它们包含相同的 Client。

一种比较参数的方式是您打算实现这样的org.hamcrest.Matcher：

class SimpleExpressionMatcher extends ArgumentMatcher<SimpleExpression> {
    private SimpleExpression simpleExpression;
    public SimpleExpressionMatcher(SimpleExpression simpleExpression) {
        this.simpleExpression = simpleExpression;
    }
    @Override
    public boolean matches(Object argument) {
        @SuppressWarnings({"unchecked", "rawtypes"})
        SimpleExpression otherSimpleExpression = (SimpleExpression) argument;
        // somehow compare the SimpleExpressions, possibly like this:
        // this.simpleExpression.toString().equals(otherSimpleExpression.toString());
    }
}

然后这样验证：

 Matcher<SimpleExpression> matcher = new SimpleExpressionMatcher(Restrictions.eq("client", selectionVariant.getClient()));
 Mockito.verify(criteria).add(Mockito.argThat(matcher));
