Write JUnit for Guice bindings of Spring beans

问题

My library uses both Guice and Spring. And I have class where Spring beans are "bind"-ed for the below usage

@ModuleDescriptor(
requires = {
  AnotherModule.class,
  SpringIntegrationModule.class,
})

public class MyModule extends AbstractModule {

@Override
protected void configure() {
bind(Command.class)
    .annotatedWith(Names.named("commandSpringBean"))
    .toProvider(
        SpringIntegration.fromSpring(Command.class, "commandSpringBean"));

AnotherModule.exportFunctions(this.binder(), MyGuiceInjector.class);

Note that AbstractModule here is com.google.inject.AbstractModule

commandSpringBean is a spring bean created in some other config file in another java package of same project. I am finally using the spring bean in MyGuiceInjector.java as below

  @Inject
  @Named("commandSpringBean")
  private Command commandSpringBean;

I want to finally write a JUnit that tests that the bean is successfully binded. If that is not possible I want to at least test that during bind(), commandSpringBean is actually of type Command.class

Is there a way I can test this?
