Re: [aspectj-users] around advice for constructor call

[Alexander Kriegisch <Alexander@xxxxxxxxxxxxxx>]

Well, Sojan, if you don't know where to get the object from how should I? ;-) I suggest you derive your ClassA by something like ClassAMock and inject it, i.e. use an instance of it as a return value. Mock testing is state of the art and you can easily return a subclass instance if the return value is ClassA. Providing a mock should be the whole purpose of your setup, I suppose.

Pretty simple, isn't it? :-)

Hi Alexander,

           Thank you for the reply. 

Basically what I need is, bypass constructor call. In around advice, from where I can get object to be returned? (I'm NOT calling proceed inside around, to bypass constructor body execution)

How can bypass constructor body execution?

Regards

Sojan

The error message says it: You are intercepting a call which does not return void (but ClassA). Consequently, your around advice should also return ClassA.

Hi AspectJ Community Members,

I'm using AOP for unit testing purpose. (to replace external dependency).

In my app, I'm creating object of ClassA (which is present in external lib). I want to byepass constructor call of ClassA .  I tried "call" pointcut and around advice as below, but it is not working

pointcut callClassANew() : call(  ClassA.new());

void around() : callClassANew() {

System.out.println("[AspectJ]callClassANew "+thisJoinPoint);

}

Error :

[AppClassLoader@fabe9] error at LibMocks.aj:28::0 applying to join point that doesn't return void: constructor-call(void ClassA.<init>())

[AppClassLoader@fabe9] error at AppTest.java:160::0 applying to join point that doesn't return void: constructor-call(void ClassA.<init>())

Thank you in advance for the support

Regards

Sojan
