Unit testing is usually done by the developer while developing the program(s) or the functional analyst could take part in this too. Really it is testing the single program or parts of the program. Intergration Testing is more left to the functional analyst and the career testers. They would be testing how the program changes effect the surrounding business processes and downsteam process.
