Annotation Interface SpyBean


Deprecated, for removal: This API element is subject to removal in a future version.
since 3.4.0 for removal in 3.6.0 in favor of MockitoSpyBean
Annotation that can be used to apply Mockito spies to a Spring ApplicationContext. Can be used as a class level annotation or on fields in either @Configuration classes, or test classes that are @RunWith the SpringRunner.

Spies can be applied by type or by bean name. All beans in the context of a matching type (including subclasses) will be wrapped with the spy. If no existing bean is defined a new one will be added. Dependencies that are known to the application context but are not beans (such as those registered directly) will not be found and a spied bean will be added to the context alongside the existing dependency.

When @SpyBean is used on a field, as well as being registered in the application context, the spy will also be injected into the field. Typical usage might be:

 @RunWith(SpringRunner.class)
 public class ExampleTests {

     @SpyBean
     private ExampleService service;

     @Autowired
     private UserOfService userOfService;

     @Test
     public void testUserOfService() {
         String actual = this.userOfService.makeUse();
         assertEquals("Was: Hello", actual);
         verify(this.service).greet();
     }

     @Configuration
     @Import(UserOfService.class) // A @Component injected with ExampleService
     static class Config {
     }


 }
 
If there is more than one bean of the requested type, qualifier metadata must be specified at field level:
 @RunWith(SpringRunner.class)
 public class ExampleTests {

     @SpyBean
     @Qualifier("example")
     private ExampleService service;

     ...
 }
 

This annotation is @Repeatable and may be specified multiple times when working with Java 8 or contained within a @SpyBeans annotation.

  • Element Details

    • name

      String name
      Deprecated, for removal: This API element is subject to removal in a future version.
      The name of the bean to spy. If not specified the name will either be generated or, if the spy is for an existing bean, the existing name will be used.
      Returns:
      the name of the bean
      Default:
      ""
    • value

      @AliasFor("classes") Class<?>[] value
      Deprecated, for removal: This API element is subject to removal in a future version.
      The classes to spy. This is an alias of classes() which can be used for brevity if no other attributes are defined. See classes() for details.
      Returns:
      the classes to spy
      Default:
      {}
    • classes

      @AliasFor("value") Class<?>[] classes
      Deprecated, for removal: This API element is subject to removal in a future version.
      The classes to spy. Each class specified here will result in a spy being applied. Classes can be omitted when the annotation is used on a field.

      When @SpyBean also defines a name this attribute can only contain a single value.

      If this is the only specified attribute consider using the value alias instead.

      Returns:
      the classes to spy
      Default:
      {}
    • reset

      MockReset reset
      Deprecated, for removal: This API element is subject to removal in a future version.
      The reset mode to apply to the spied bean. The default is MockReset.AFTER meaning that spies are automatically reset after each test method is invoked.
      Returns:
      the reset mode
      Default:
      AFTER
    • proxyTargetAware

      boolean proxyTargetAware
      Deprecated, for removal: This API element is subject to removal in a future version.
      Indicates that Mockito methods such as verify(mock) should use the target of AOP advised beans, rather than the proxy itself. If set to false you may need to use the result of AopTestUtils.getUltimateTargetObject(...) when calling Mockito methods.
      Returns:
      true if the target of AOP advised beans is used or false if the proxy is used directly
      Default:
      true
