我在下面有 void 方法,我想得到嘲笑。
public void updateEmployee(EmployeeDto dto) {
Employee d = convertToEntity(dto);
employeeRepository.updateEmployee(d.getEmployeeName(), d.getEmployeeDescription(),
d.getEmployeeOwnerEmployeeId(), d.getEmployeeCode(), d.getStatus());
}
但是我得到了以下错误。
org.mockito.exceptions.misusing.NotAMockException:
Argument passed to when() is not a mock!
Example of correct stubbing:
doThrow(new RuntimeException()).when(mock).someMethod();

测试方法
@RunWith(PowerMockRunner.class)
@PrepareForTest({StatusEnum.class})
public class EmployeeServiceTest {
@Mock
private Employee employeeMock;
@InjectMocks
private EmployeeServiceImpl employeeServiceImpl;
@Mock
private EmployeeRepository employeeRepositoryMock;
@Mock
private EmployeeDto employeeDtoMock;
@Mock
private StatusEnum statusEnum;
@Mock
private Exception ex;
List<String> employeeNames = new ArrayList<>();
@Before
public void setup() {
// To mock static methods or class
mockStatic(StatusEnum.class);
}
@Test
public void test_UpdateEmployee() {
doNothing().when(employeeServiceImpl).saveEmployee(any(EmployeeDto.class));
employeeServiceImpl.updateEmployee(employeeDtoMock);
/*doAnswer((i) -> {
System.out.println("Employee setName Argument = " + i.getArgument(0));
assertTrue("Pankaj".equals(i.getArgument(0)));
return null;
}).when(employeeServiceImpl).updateEmployee(employeeDtoMock);*/
}
}
这里的例外对我来说似乎很清楚,employeeServiceImpl
似乎不是模拟。 你是如何实例化的?在球场上使用Mockito.mock
或@Mock
?
---编辑
为了澄清我的答案,在@Before
(或测试类中的等效项)中,使用 mockito 实例化您的服务:
this.employeeService = Mockito.mock(EmployeeService.class);
或
@Mock
private EmployeeService employeeService;
然后它应该起作用。
---编辑 所以看到你如何注入你的模拟,我想我可能会明白发生了什么。 事实上,@InjectMocks
不会让你EmployeeService a mock
.它允许 mockito 知道让你的框架创建 bean 并在其中注入你创建的模拟。
在这里,如果您已将存储库声明为这样的模拟
@Mock
private EmployeeRepository employeeRepository;
然后,将在employeeService
实例中注入EmployeeRepository
类型的模拟,这不是模拟。
然后,如果它实际上是您要模拟的存储库,则应将其放在测试的when
中,例如:
doNothing().when(employeeRepository).saveEmployee(any(EmployeeDto.class));
employeeServiceImpl.saveEmployee(employeeDtoMock);
然后调用您的服务将进入您的服务saveEmployee
函数,但是当它到达模拟存储库时,它将按预期工作。
如果它实际上是您要模拟的整个服务,则使用@Mock
而不是@InjectMocks
来实例化它。
