Hi all,I am a QA and encount a problem that i need to know what would be affected by the code changes dev made.

There came an idea for me that i could analysis ast for each java file to get its calling relationship.

When analysing ast, i choose MethodInvoke node so that i could get the caller and callee.Then i encount my problem that i found the callee i got is a interface for which i can find many implement,but i can't distinguish which one is the actually called one.

Any ideas/comments/questions would be greatly appreciated.

If I understand the question correctly, you can't statically know (in
general) which implementation class will be used at runtime by a call
through an interface.
