我是TDD和mockito的新手,我正在尝试将mocks注入类中以执行单元测试,该类根据某些验证在方法中实例化其依赖项,我收到错误
测试类/方法
//Its interface
public interface UserService {
public Debt getCustomerDebt(String id);
}
//validator method
public static boolean isValidId(String id){
if(id != null && !id.isEmpty() && !id.trim().equals("")){
return true;
}
return false;
}
public class UserServiceImpl implements UserService {
private Repository repo;
private WSDLCustomerDebt wsdlCostumerDebt;
public static final int USER_EXIST = 1;
public static final int USER_DOESNOT_EXIST = 0;
public UserServiceImpl(){
}
public Debt getCustomerDebt(String id) {
if(ValidatorHelper.isValidId(id)){
repo = new RepositoryImpl();
int exist = repo.getCustomer(id);
if(exist==USER_EXIST){
wsdlCostumerDebt = new WSDLCustomerDebtImpl();
List<Date> meses = wsdlCostumerDebt.obtenerMeses(id);
if(meses.size()>0){
int totalDebt = 0;
for (Date mes : meses){
totalDebt += wsdlCostumerDebt.obtenerDeuda(mes, id);
}
return new Debt(id, BigDecimal.valueOf(totalDebt));
}else{
return new Debt(id, BigDecimal.valueOf(0));
}
}
}
return null;
}
}
模拟类repositoryimpl
public class RepositoryImpl implements Repository {
public int getCustomer(String id) {
int y = Integer.valueOf(1);
return y;
}
}
wsdl模拟了类
//Interface
public interface WSDLCustomerDebt {
public List<Date> obtenerMeses(String customerId);
public Integer obtenerDeuda(Date month, String customerId);
}
public class WSDLCustomerDebtImpl implements WSDLCustomerDebt {
public List<Date> obtenerMeses(String customerId) {
return null;
}
public Integer obtenerDeuda(Date month, String customerId) {
Integer y = Integer.valueOf(11);
return y;
}
}
域名类债务
public class Debt {
private String id;
private BigDecimal debt;
public Debt(String id, BigDecimal debt) {
super();
this.id = id;
this.debt = debt;
}
//Getters and setters ....
}
最后测试课程
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.MockitoAnnotations;
public class UserServiceImplTest {
@Mock
private Repository repo;
@Mock
private WSDLCustomerDebt wsdlCustomerDebt;
@InjectMocks
private UserServiceImpl userService;
@Before
public void init(){
//repo=Mockito.mock(Repository.class);
//when(wsdlcustomer.obtenerDeuda(D, customerId))
MockitoAnnotations.initMocks(this);
}
@Test
public void noExistingCustomer(){
//Given:
String id = "123";
//When:
Mockito.when(repo.getCustomer(id)).thenReturn(0);
Debt debt = userService.getCustomerDebt(id);
Mockito.verify(repo.getCustomer(Mockito.any(String.class)));
//Then:
assertNull(debt);
}
}
这是我得到的错误,我试图避免使用构造函数或任何getter / setter并通过参数接收模拟,也许它可能是由于一个虚拟错误引起的,但此时我并没有知道我做错了什么,事实上我认为问题的出现是因为模拟类中的return语句。我正在使用mockito版本1.9.5 btw
org.mockito.exceptions.misusing.NotAMockException:
Argument passed to verify() is of type Integer and is not a mock!
Make sure you place the parenthesis correctly!
See the examples of correct verifications:
verify(mock).someMethod();
verify(mock, times(10)).someMethod();
verify(mock, atLeastOnce()).someMethod();

答案 0 :(得分:2)
首先,您的服务不使用您正在注入的模拟,因为它在您调用方法时会创建一个新模拟。 repo应该是服务构造函数的参数。
其次,验证调用mock方法的正确语法不是
verify(mock.method())
但
verify(mock).method()
(如错误信息所示)。
所以,行
Mockito.verify(repo.getCustomer(Mockito.any(String.class)))
必须替换为
Mockito.verify(repo).getCustomer(Mockito.any(String.class))
