Change springs behavior on NoSuchBeanDefinitionException

Question

In integration tests with spring application context I write quite often something like this in my configuration classes

@Bean
public MyComponent myComponent() {
   return mock(MyComponent.class);
}

Sometimes I have to create those beans just to fulfill dependency requirements, sometimes I wire those mocks in my test to configure them.

In any case I'd love to get rid off those bean definitions. Is there a way to tell spring to create a mock of a type it is missing instead of throwing NoSuchBeanDefinitionException?

Have a look at spring-auto-mock.

By registering the AutoMockRegistryPostProcessor all the dependencies that Spring cannot find will be automagically converted to mockito mocks.

Here you have a test example.
