Hi, I am an expert in Java and well experiences with Junit 3, and 4 and other testing tools (Jenkins, Mockito, Robotium).
I think that you want to automatically generate test cases from existing code (using annotations or others), wooow its so excited project but very difficult in the same time and is relative to target platform (Android, classic JVM, server JVM, etc).
I have a master degree in computer science and I love working on these project.
We can talk about your project and exchange ideas.
