Even with a built-in garbage collector, Java programs still suffer from memory leak problems caused by useless references to stale objects. Lots of researches have been conducted for the diagnosing of leaking failures. However, testing and identifying the leaking runs, which act as key steps before diagnosing, are still challenging. In this paper, we introduce a leak specification tool named LeakSpec to help programmers test memory leaks in Java programs. The specification works as a test oracle to automatically determine whether a program suffers from memory leaks. Users can write their own leak specifications using our specification language. LeakSpec weaves the specification checking mechanisms into the tested programs. During test runs, a memory leak failure will be reported if the some specifications are not satisfied. With this specification-based approach, a tester does not need to manually watch the program executions to identify memory leaks. The automatically reporting of memory leaks can reduce the manual efforts in leak testing. We test the proposed approach on ArgoUML. The results show that it is effective.?????
