Many developers would inject mocks in beans during tests through `@InjectMock` or using manual setters and often forget to set back the original field values which would leave the Spring context polluted and cause test failures in unrelated tests. 14 | 15 | @MockBean and @SpyBean solved this issue by providing Mockito injection directly in the Spring Context but introduced an undesirable side-effect: their usage dirties the context and may lead to the re-creation of new Spring contexts for any unique combination, which can be incredibly time-consuming. See [The Problems with @MockBean](https://www.baeldung.com/spring-tests#2-the-problems-withmockbean) 16 | 17 | ### The solution: 18 | 19 | Assuming you really need to run the test in the Spring Context, the most straight-forward solution is still to inject your mock/spy in your bean and reset it afterwards. 20 | 21 | **@MockInBean and @SpyInBean brings the convenience of @MockBean and @SpyBean and do just that:** 22 | 1. Set the mock/spy in the bean. 23 | 2. Replace the mock/spy by the original value afterwards. 24 | 25 | # Example: 26 | 27 | Assuming that you want to test the following service: 28 | ```java 29 | @Service 30 | public class MyService { 31 | 32 | @Autowired 33 | protected ThirdPartyApiService thirdPartyService; 34 | 35 | @Autowired 36 | protected ExpensiveProcessor expensiveProcessor; 37 | 38 | public void doSomething() { 39 | final Object somethingExpensive = expensiveProcessor.returnSomethingExpensive(); 40 | thirdPartyService.doSomethingOnThirdPartyApi(somethingExpensive); 41 | } 42 | 43 | } 44 | 45 | ``` 46 | 47 | You can write your test this way: 48 | ```java 49 | @SpringBootTest 50 | public class MyServiceTest { 51 | 52 | @MockInBean(MyService.class) 53 | private ThirdPartyApiService thirdPartyApiService; 54 | 55 | @SpyInBean(MyService.class) 56 | private ExpensiveProcessor expensiveProcessor; 57 | 58 | @Autowired 59 | private MyService myService; 60 | 61 | @Test 62 | public void test() { 63 | final Object somethingExpensive = new Object(); 64 | Mockito.when(expensiveProcessor.returnSomethingExpensive()).thenReturn(somethingExpensive); 65 | myService.doSomething(); 66 | Mockito.verify(thirdPartyApiService).doSomethingOnThirdPartyApi(somethingExpensive); 67 | } 68 | 69 | } 70 | ``` 71 | 72 | **What happens**: 73 | 74 | Before each test: 75 | - `MyServiceTest.thirdPartyService` will be created as a mock and injected in the target of @MockInBean: `MyService`. 76 | - `MyServiceTest.expensiveProcessor` will be created as a spy of the bean `expensiveProcessor` and injected in the target of @SpyInBean: `MyService`. 77 | 78 | After the tests of `MyServiceTest` are done: 79 | - `MyService.thirdPartyService` will be reset to the original Spring bean `thirdPartyService` 80 | - `MyService.expensiveProcessor` will be reset to the original Spring bean `expensiveProcessor` 81 | 82 | # Usage: 83 | 84 | Simply include the maven dependency (from central maven) to start using @MockInBean and @SpyInBean in your tests. 85 | ``` 86 | 87 | com.teketik 88 | mock-in-bean 89 | boot2-v1.9 90 | test 91 | 92 | ``` 93 | 94 | @MockInBean and @SpyInBean also support: 95 | - Injection in multiple Spring beans: *Repeat the annotation on your field*. 96 | - Injection in bean identified by name if multiple instances exist in the context: *Specify a `name` in your annotation*. 97 | 98 | Checkout the javadoc for more information. 99 | 100 | # Limitations: 101 | 102 | This approach has some limitations compared to the @MockBean/@SpyBean equivalent: 103 | - There is currently no isolation per thread. It is not advised to use this library in parallel test suites. (Parallel test execution is supported experimentally in https://github.com/antoinemeyer/mock-in-bean/tree/v2.1-RC). 104 | - Operations on beans happening within another bean's constructor will not be performed against the mocks since the mocks are injected directly into the fields. Do not use @MockInBean/@SpyInBean for beans that are manipulated in constructors. 105 | -------------------------------------------------------------------------------- /pom.xml: -------------------------------------------------------------------------------- 1 | 4 | 5 | 4.0.0 6 | com.teketik 7 | mock-in-bean 8 | boot2-v1.9 9 | Mock in Bean 10 | Surgically Inject Mockito Mock/Spy in Spring Beans 11 | https://github.com/antoinemeyer/mock-in-bean 12 | 13 | https://github.com/antoinemeyer/mock-in-bean 14 | scm:git:git://github.com/antoinemeyer/mock-in-bean.git 15 | scm:git:git@github.com:antoinemeyer/mock-in-bean.git 16 | 17 | 18 | 19 | 20 | The Apache License, Version 2.0 21 | http://www.apache.org/licenses/LICENSE-2.0.txt 22 | 23 | 24 | 25 | 26 | 27 | Antoine Meyer 28 | 29 | 30 | 31 | 32 | 1.8 33 | 1.8 34 | 35 | 36 | 37 | org.springframework.boot 38 | spring-boot-dependencies 39 | 2.6.15 40 | 41 | 42 | 43 | 44 | 45 | org.springframework.boot 46 | spring-boot-test 47 | 48 | 49 | org.springframework 50 | spring-test 51 | 52 | 53 | org.mockito 54 | mockito-core 55 | 56 | 57 | org.junit.jupiter 58 | junit-jupiter-api 59 | 60 | 61 | 62 | 63 | org.springframework.boot 64 | spring-boot-starter-aop 65 | test 66 | 67 | 68 | org.springframework.boot 69 | spring-boot-starter-test 70 | test 71 | 72 | 73 | org.springframework.boot 74 | spring-boot-starter-data-jpa 75 | test 76 | 77 | 78 | com.h2database 79 | h2 80 | test 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | org.apache.maven.plugins 89 | maven-source-plugin 90 | 91 | 92 | attach-sources 93 | 94 | jar 95 | 96 | 97 | 98 | 99 | 100 | org.apache.maven.plugins 101 | maven-javadoc-plugin 102 | 103 | 104 | attach-javadocs 105 | 106 | jar 107 | 108 | 109 | 110 | 111 | 112 | org.apache.maven.plugins 113 | maven-gpg-plugin 114 | 115 | 116 | sign-artifacts 117 | verify 118 | 119 | sign 120 | 121 | 122 | 123 | 124 | 125 | org.sonatype.plugins 126 | nexus-staging-maven-plugin 127 | true 128 | 129 | ossrh 130 | https://oss.sonatype.org/ 131 | true 132 | 133 | 134 | 135 | 136 | 137 | -------------------------------------------------------------------------------- /src/main/java/com/teketik/test/mockinbean/BeanFieldState.java: -------------------------------------------------------------------------------- 1 | package com.teketik.test.mockinbean; 2 | 3 | import org.springframework.test.context.TestContext; 4 | import org.springframework.util.ReflectionUtils; 5 | 6 | import java.lang.reflect.Field; 7 | 8 | class BeanFieldState extends FieldState { 9 | 10 | final Object bean; 11 | 12 | final Object originalValue; 13 | 14 | public BeanFieldState(Object bean, Field field, Object originalValue, Definition definition) { 15 | super(field, definition); 16 | this.bean = bean; 17 | this.originalValue = originalValue; 18 | } 19 | 20 | @Override 21 | public Object resolveTarget(TestContext testContext) { 22 | return bean; 23 | } 24 | 25 | public void rollback(TestContext testContext) { 26 | final Object target = resolveTarget(testContext); 27 | ReflectionUtils.setField(field, target, originalValue); 28 | } 29 | 30 | public Object createMockOrSpy() { 31 | return definition.create(originalValue); 32 | } 33 | 34 | } 35 | -------------------------------------------------------------------------------- /src/main/java/com/teketik/test/mockinbean/BeanUtils.java: -------------------------------------------------------------------------------- 1 | package com.teketik.test.mockinbean; 2 | 3 | import org.springframework.aop.TargetSource; 4 | import org.springframework.aop.framework.Advised; 5 | import org.springframework.aop.framework.AopProxyUtils; 6 | import org.springframework.aop.support.AopUtils; 7 | import org.springframework.context.ApplicationContext; 8 | import org.springframework.lang.Nullable; 9 | import org.springframework.util.Assert; 10 | import org.springframework.util.ReflectionUtils; 11 | 12 | import java.lang.reflect.Field; 13 | import java.util.Map; 14 | import java.util.Map.Entry; 15 | 16 | abstract class BeanUtils { 17 | 18 | private BeanUtils() { 19 | } 20 | 21 | /** 22 | *

Annotation used to inject a mockito {@link Mock} in a Spring Bean for the duration of a test. 14 | *

This is a convenient alternative to {@link MockBean @MockBean} that provides surgical mock injection without dirtying or polluting the Spring context:
15 | * Mocks are injected for every test method and the original Spring Beans(s) are re-injected after the test class is done. 16 | *


17 | *

Example:
18 | * Assuming you have the following service:
19 | *

20 |  * @Service
21 |  * public class MyService {
22 |  *
23 |  *     @Autowired
24 |  *     private ThirdPartyApi thirdPartyApi;
25 |  *
26 |  *     public Object returnSomethingFromThirdPartyApi() {
27 |  *         return thirdPartyApi.returnSomething();
28 |  *     }
29 |  * }
30 |  * 
31 | * You can create a test for your service with a mocked {@code ThirdPartyApi} like: 32 | *
33 |  * @SpringBootTest
34 |  * public class MyServiceTest {
35 |  *
36 |  *     @MockInBean(MyService.class)
37 |  *     private ThirdPartyApi thirdPartyApi;
38 |  *
39 |  *     @Autowired
40 |  *     private MyService myService;
41 |  *
42 |  *     @Test
43 |  *     public void test() {
44 |  *         final Object expected = new Object();
45 |  *         Mockito.when(thirdPartyApi.returnSomething()).thenReturn(expected);
46 |  *         final Object actual = myService.returnSomethingFromThirdPartyApi();
47 |  *         Assert.assertEquals(expected, actual);
48 |  *     }
49 |  * }
50 |  * 
51 | * {@code thirdPartyApi} will be a {@link Mock} that is recreated for every test method in {@code MyServiceTest} and {@code MyService}.
52 | * The original {@code ThirdPartyApi} Spring bean will be re-injected in {@code MyService} after all the tests of {@code MyServiceTest}. 53 | *
54 | *

In case the bean in which you are trying to inject a mock has multiple instances registered in the context, you can specify the {@link #name() name} of the bean: 55 | *

56 |  * @MockInBean(value = MyService.class, name = "nameOfMyService")
57 |  * private ThirdPartyApi thirdPartyApi;
58 |  * 
59 | *
60 | *

You can also inject your mock in multiple beans by repeating the annotation: 61 | *

62 |  * @MockInBean(MyFirstService.class),
63 |  * @MockInBean(MySecondService.class)
64 |  * private ThirdPartyApi thirdPartyApi;

30 |  * 
31 | * You can create a test for your service with a spied {@code ThirdPartyApi} like: 32 | *
33 |  * @SpringBootTest
34 |  * public class MyServiceTest {
35 |  *
36 |  *     @SpyInBean(MyService.class)
37 |  *     private ThirdPartyApi thirdPartyApi;
38 |  *
39 |  *     @Autowired
40 |  *     private MyService myService;
41 |  *
42 |  *     @Test
43 |  *     public void test() {
44 |  *         myService.doSomethingWithThirdPartyApi();
45 |  *         Mockito.verify(thirdPartyApi).doSomething(Mockito.any(Object.class));
46 |  *     }
47 |  * }
48 |  * 
49 | * {@code thirdPartyApi} will be a {@link Spy} of the actual {@code ThirdPartyApi} Spring Bean that is recreated for every test method in {@code MyServiceTest} and {@code MyService}.
50 | * The original {@code ThirdPartyApi} Spring bean will be re-injected in {@code MyService} after all the tests of {@code MyServiceTest}. 51 | *
52 | *

In case the bean in which you are trying to inject a spy has multiple instances registered in the context, you can specify the {@link #name() name} of the bean: 53 | *

54 |  * @SpyInBean(value = MyService.class, name = "nameOfMyService")
55 |  * private ThirdPartyApi thirdPartyApi;
56 |  * 
57 | *
58 | *

You can also inject your spy in multiple beans by repeating the annotation: 59 | *

60 |  * @SpyInBean(MyFirstService.class),
61 |  * @SpyInBean(MySecondService.class)
62 |  * private ThirdPartyApi thirdPartyApi;
