Data for Effective Unit Test Generation for Java Null Pointer Exceptions

This is to provide all contents of our work, NPETest, including all raw experimental data used in our paper which will be published at ASE`24.

NPETest is an unit test generation tool for Java projects, which utilizes both static and dynamic analysis techniques for effective NPE detection. This tool is implemented on the top of EvoSuite, a publicly available unit test generation tool for Java.

For more technical details, please read our paper which will be published at ASE`24.
