我在spring-mvc有项目。我在mockito中写了一个测试用例，下面是代码：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:applicationContext.xml"})
@Configurable
public class ABCControllerTest {
@InjectMocks
CustomerController instance;
@Mock
Service paymentService;
@Mock
OfferService offerService;
@Mock
CategoryRepository categoryRepository;
@Mock
Category category;
@Mock
RuleService ruleService ;
private MockMvc mockMvc;
public PaymentCustomerControllerTest() {
}
@Before
public void setup() {
// this must be called for the @Mock annotations above to be processed
// and for the mock service to be injected into the controller under
// test.
MockitoAnnotations.initMocks(this);
mockMvc = MockMvcBuilders.standaloneSetup(instance).build();
}
@Test
public void testGetNewCashback() throws Exception {
int a= 100;
int b=200;
// System.out.print(mockMvc);
try{
mockMvc.perform(
get("repo/getTotalSum?Id=306187C35A5C98A1B01E3DCDE8BAC1DA&visitId=306187C35A5C98A1B01E3DCDE8BAC1DA&mobileStatus=0"))
.andExpect(MockMvcResultMatchers.status().isOk());
}catch(Exception ex){
System.out.print(ex.getMessage());
}
a = 100;
}
@Test
public void testGetNewCashback() throws Exception {
ResultDTO result = instance.getTotalSum(Id, visitId, mobileStatus);
assertEquals(result, expResult);
// TODO review the generated test code and remove the default call to fail.
fail("The test case is a prototype.");
}
}
这是我的pom文件：

at the value of mock is getting null, so getting null pointer exception. I googled out, changed spring version to 4.0.0Release, still same.
有什么想法吗？感谢。
更改为独立后：我收到java.lang.Exception：mvc的值为null。这是我的代码
@RunWith(MockitoJUnitRunner.class)
@ContextConfiguration({"classpath:applicationContext.xml"})
@WebAppConfiguration
public class PaymentCustomerControllerTest {
@Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
@Before
public void setUp() {
MockitoAnnotations.initMocks(this);
CustomerController instance = new CustomerController();
mockMvc = MockMvcBuilders.standaloneSetup(instance).build();
}
@Test
public void testGetNewCashback() throws Exception {
if(mockMvc==null){
throw new Exception("mvc is having null value");
}
mockMvc.perform(
get("info/getInfo?Id=306&visitId=30618&mobileStatus=0"))
.andExpect(MockMvcResultMatchers.status().isOk());
}
答案 0 :(得分：-1)
如果您想使用Mockito进行测试，则必须使用MockitoJUnitRunner而不是SpringJUnit4ClassRunner
