我正在尝试在Spring Boot中测试我的代码，但是我发现了
java.lang.NullPointerException
运行代码时例外。这是我的模特：

和
package com.Loyalty.OpenLoyalty.Models.User.Projections;
import com.Loyalty.OpenLoyalty.Models.User.ol__user;
import java.util.ArrayList;
import java.util.List;
public class ol__users {
private List<ol__user> usersList;
public List<ol__user> getUsersList(){
if (usersList== null){
usersList=new ArrayList<>();
}
return usersList;
}
public void setUsersList(List<ol__user> usersList){
this.usersList= usersList;
}
}
我的控制器：
@GetMapping("/admin")
public ol__users getAllAdminUsers( ){
return userService.getAllAdminUsers();
}
我的服务：
@Service
public class userService {
@Autowired
private userRepository userRepository;
public ol__users getAllAdminUsers( ){
ol__users response = new ol__users();
ArrayList<ol__user> list=new ArrayList<>();
userRepository.find
Bydtype("admin").forEach(e ->list.add(e));
response.setUsersList(list);
return response;
}
}
和我的存储库：
@Repository
public interface userRepository extends JpaRepository<ol__user, String> {
List<ol__user> findBydtype(String dtype);
Optional<ol__user> findById(String id);
Boolean existsByUsername(String username);
ol__user findByUsername(String username);
ol__user findByEmail(String username);
ol__user findByEmailIgnoreCase(String email);
// @Query(value = "select count(*) as count from ol__user",nativeQuery = true)
}
最后是我的测试代码：
ExtendWith(MockitoExtension.class)
@RunWith(MockitoJUnitRunner.class)
public class Ol_userControllerTest {
@InjectMocks
Ol__userController Ol__userController;
@Mock
userRepository userRepository;
@Mock
userService userService;
@Test
@Transactional
public void testFindAll(){
ol__roles role=new ol__roles();
role.setName("tests");
role.setRole("Admin");
role.setIs_master(true);
Timestamp currentSqlTimestamp = new Timestamp(System.currentTimeMillis());
ol__user user1=new ol__user("anteaaa","nejatiaan","[email protected]","anteaaaaa","12345","admin",true,role,"123",currentSqlTimestamp);
ol__user user2=new ol__user("Nooria","Rajaee","[email protected]","Nooriaa","12345","admin",true,role,"123",currentSqlTimestamp);
List<ol__user> list = new ArrayList<ol__user>();
list.addAll(Arrays.asList(user1,user2));
Mockito.when(userRepository.findBydtype(any())).thenReturn(list);
//when
ol__users result = userService.getAllAdminUsers();
//then
assertThat(result.getUsersList().size()).isEqualTo(2);
assertThat(result.getUsersList().get(0).getFirst_name())
.isEqualTo(user1.getFirst_name());
}
}
我已经公开了我的代码，但我知道
Mockito.when(userRepository.findBydtype(any())).thenReturn(list);
将列表存储在其中，但是在下一行中，我的结果对象返回null，然后发生异常。我想知道我的问题在哪里吗？
是，因为您正在测试控制器并将模拟注入到控制器，所以控制器中的服务被模拟并且getAllAdminUsers()返回null。
您应该为控制器编写一个测试，为服务编写另一个测试
ExtendWith(MockitoExtension.class)
@RunWith(MockitoJUnitRunner.class)
public class ControllerTest {
@InjectMocks
private Ol__userController Ol__userController;
@Mock
private userRepository userRepository;
@Mock
private userService userService;
@Test
public void testFindAll(){
// Arrange
ol__roles role=new ol__roles();
role.setName("tests");
role.setRole("Admin");
role.setIs_master(true);
Timestamp currentSqlTimestamp = new Timestamp(System.currentTimeMillis());
ol__user user1=new ol__user("anteaaa","nejatiaan","[email protected]","anteaaaaa","12345","admin",true,role,"123",currentSqlTimestamp);
ol__user user2=new ol__user("Nooria","Rajaee","[email protected]","Nooriaa","12345","admin",true,role,"123",currentSqlTimestamp);
List<ol__user> list = new ArrayList<ol__user>();
list.addAll(Arrays.asList(user1,user2));
Mockito.when(ol__users result = userService.getAllAdminUsers()
).thenReturn(list);
// Act
List<ol__user> actual = Ol__userController.getAllAdminUsers();
// Assert
assertThat(actual.getUsersList().size()).isEqualTo(2);
assertThat(actual.getUsersList().get(0).getFirst_name())
.isEqualTo(user1.getFirst_name());
}
}
，服务测试
ExtendWith(MockitoExtension.class)
@RunWith(MockitoJUnitRunner.class)
public class ServiceTest {
@InjectMocks
private userService userService;
@Mock
private userRepository userRepository;
@Test
public void testFindAll(){
// Arrange
ol__roles role=new ol__roles();
role.setName("tests");
role.setRole("Admin");
role.setIs_master(true);
Timestamp currentSqlTimestamp = new Timestamp(System.currentTimeMillis());
ol__user user1=new ol__user("anteaaa","nejatiaan","[email protected]","anteaaaaa","12345","admin",true,role,"123",currentSqlTimestamp);
ol__user user2=new ol__user("Nooria","Rajaee","[email protected]","Nooriaa","12345","admin",true,role,"123",currentSqlTimestamp);
List<ol__user> list = new ArrayList<ol__user>();
list.addAll(Arrays.asList(user1,user2));
when(userRepository.findBydtype(any())).thenReturn(list);
// Act
ol__users result = userService.getAllAdminUsers();
//Assert
assertThat(result.getUsersList().size()).isEqualTo(2);
assertThat(result.getUsersList().get(0).getFirst_name())
.isEqualTo(user1.getFirst_name());
}
}
