/**
* Annotation that can be used to apply Mockito spies to a Spring
* {@link ApplicationContext}. Can be used as a class level annotation or on fields in
* either {@code @Configuration} classes, or test classes that are
* {@link RunWith @RunWith} the {@link SpringRunner}.
* <p>
* Spies can be applied by type or by {@link #name() bean name}. All beans in the context
* of the same type will be wrapped with the spy. If no existing bean is defined a new one
* will be added.
* <p>
* When {@code @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: <pre class="code">
* @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 {
* }
*
*
* }
* </pre> If there is more than one bean of the requested type, qualifier metadata must be
* specified at field level: <pre class="code">
* @RunWith(SpringRunner.class)
* public class ExampleTests {
*
* @SpyBean
* @Qualifier("example")
* private ExampleService service;
*
* ...
* }
* </pre>
* <p>
* This annotation is {@code @Repeatable} and may be specified multiple times when working
* with Java 8 or contained within a {@link SpyBeans @SpyBeans} annotation.
