    isNull(method);
    // NOT null in case of AroundConstruct
    Constructor ctor = context.getConstructor();
    isNotNull(ctor);
    // perform the constructor injection
    Object result = context.proceed();
    isNull(result);
    // NOT null after the InvocationContext.proceed() completes
    target = context.getTarget();
    isNotNull(target);
    // a constructor should have been called
    GreetingBean bean = (GreetingBean) target;
    isBoolean(bean.isConstructed(), true);
    isBoolean(bean.isInitialized(), false);
    // constructor injection should have been done
    isNotNull(bean.getParam());
    return null;
}
