Abstract

Static state is common in object-oriented programs. However, automatic test case generators do not take into account the potential interference of static state with a unit under test and may, thus, miss subtle errors. In particular, existing test case generators do not treat static fields as input to the unit under test and do not control the execution of static initializers. We address these issues by presenting a novel technique in automatic test case generation based on static analysis and dynamic symbolic execution. We have applied this technique on a suite of open-source applications and found errors that go undetected by existing test case generators. Our experiments show that this problem is relevant in real code, indicate which kinds of errors existing techniques miss, and demonstrate the effectiveness of our technique.
