[英]Mockito Tests Pass individually but fail as part of a suite
I have a case where my mockito tests all pass individually but can fail when run as part of a testing suite.我有一个案例,我的模拟测试全部单独通过,但作为测试套件的一部分运行时可能会失败。 I am using mockito version 2.9.0我正在使用 mockito 版本 2.9.0
My test class is as follows我的测试类如下
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.BDDMockito;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;
import com.cache.CacheServices;
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(value={"classpath:generalConfig/generalConfigMocks-context.xml"})
public class GeneralConfigAPIClientTest {
private MockMvc mockMvc;
@Autowired
CacheServices cacheServices;
@Autowired
IGeneralConfigServices generalConfigServices;
@Autowired
private WebApplicationContext wac;
/**
* Set up the test context, initialize the mockMvc.
* */
@Before
public void setUp() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}
@Test
public void testEmptyGeneralConfigCache_FailureFalseReturned() throws Exception {
BDDMockito.given(cacheServices.emptyCacheContents(BDDMockito.anyString())).willReturn(false);
this.mockMvc.perform(get("/generalConfig/emptyGeneralConfigCache"))
.andExpect(status().isOk())
.andReturn();
BDDMockito.verify(cacheServices, BDDMockito.times(1)).emptyCacheContents(BDDMockito.anyString());
}
@Test
public void testEmptyGeneralConfigCache_SuccessTrueReturned() throws Exception {
BDDMockito.given(cacheServices.emptyCacheContents(BDDMockito.anyString())).willReturn(true);
this.mockMvc.perform(get("/generalConfig/emptyGeneralConfigCache"))
.andExpect(status().isOk())
.andReturn();
BDDMockito.verify(cacheServices, BDDMockito.times(1)).emptyCacheContents(BDDMockito.anyString());
}
}
The contents of generalConfig/generalConfigMocks-context.xml are as follows generalConfig/generalConfigMocks-context.xml 的内容如下

A sample error response I get from running my tests is as follows我从运行测试中得到的示例错误响应如下
org.mockito.exceptions.verification.TooManyActualInvocations:
cacheServices.emptyCacheContents(

);
Wanted 1 time:

But was 2 times. Undesired invocation:

Can anyone offer any insights as to why my tests are passing individually but failing as a group任何人都可以提供有关为什么我的测试单独通过但作为一个组失败的任何见解
Reason: your test load one application context with bean mock inside. 原因:您的测试在内部使用bean mock加载一个应用程序上下文。 The bean mocks are dirty after any test. 任何测试后豆粪都很脏。 You have a dirty application context also. 您也有一个脏的应用程序上下文。
Solution: you have to clean bean mock. 解决方案:你必须清理bean mock。 Using Mockito.reset(mocks) after each test. 每次测试后使用Mockito.reset(模拟)。 I've found sth similar: How to clean up mocks in spring tests when using Mockito 我发现类似: 如何在使用Mockito时在弹簧测试中清理模拟
I am late in the game, but thought that this could be useful for people that are still experiencing the same issue(source: https://reflectoring.io/clean-unit-tests-with-mockito/ ):我在游戏中迟到了,但认为这对仍然遇到相同问题的人可能有用(来源: https : //reflectoring.io/clean-unit-tests-with-mockito/ ):
class CityServiceImplTest {
// System under Test (SuT)
private CityService cityService;
// Mock
private CityRepository cityRepository;
@BeforeEach
void setUp() {
cityRepository = Mockito.mock(CityRepository.class);
cityService = new CityServiceImpl(cityRepository);
}
// Test cases omitted for brevity.
}
With this approach, I eliminated the @SpringBootTest annotation altogether and made the test class very light weight.通过这种方法,我完全消除了 @SpringBootTest 注释,并使测试类的重量非常轻。
I faced with this problem too and solved the problem like this;我也遇到了这个问题,解决了这个问题;
Added these 3 annotations to my test classs:将这 3 个注释添加到我的测试类中:
@RunWith(SpringRunner.class)
@TestPropertySource(properties = {
"spring.jpa.hibernate.ddl-auto=none"
})
@SpringBootTest
Created Mocks with:创建的模拟:
@InjectMocks
private ImplService service;
@Mock
private MailService mailService;
In the set up:在设置中:
@Before
public void setUp() {
LockAssert.TestHelper.makeAllAssertsPass(true);
MockitoAnnotations.initMocks(this);
// In case if you are using "environment" in your
ReflectionTestUtils.setField(service, "environment", "testEnvironment");
....
}
