摘要

To evaluate this approach, we have built a prototype based on AspectJ compiler to build code and tests and with JUnit as the testing library. Early experiments show that it appears to generate and run the mutants a few orders of magnitude faster that the popular Jester. The savings result mainly from the fact that the tool does not require multiple mutant compilations, reduces the number of equivalent and transparent mutants, and preserves the syntactic correctness of the mutated code. However, it differs from Jester in that it learns the code usage from existing test cases, and then mutates the code. Jester, on the other hand, mutates the code insight into test cases, which allows for assessing the code coverage, but also leads to redundant or transparent mutants. Currently the prototype deals only with primitive Java types and null values for objects. In future, we plan to employ an on-fly object creation with dynamic proxies and implement other mutation operators as well as perform a larger scale evaluation.
