VsusFL: Variable suspiciousness based Fault Localization for Debugging Novice Programs

Introduction

This project corresponds to the experiments and results in the paper Ask Variables: Variable Values Sequence Matching Based Fault Localization (doi links will be added in the future).
The dataset is in the folder ITSP-data.

Call the function Snooper.get_cpp_variable_sequence(file_path, test_dir_path), and the returned parameter is the corresponding variable value sequences. where file_path is the code path and test_dir_path is the test case suite path.

In the file VSBFL.py, call the function run_dir(file_dir_path, pair_info, test_dir_path) to start the experiment, note that you need to change the corresponding parameters.
In function run_dir(file_dir_path, pair_info, test_dir_path), parameter pair_info is the matching relationship between correct programs and faulty programs, which can be obtained by function find_pair_by_tag or find_pair_by_res. The difference is that find_pair_by_tag is the pairing relationship given by the dataset, while find_pair_by_res is the pairing relationship given by the method in this paper.
The experimental results are saved in the path set by the parameter res_file_temp, and this excel file needs to be created by yourself first.
If you want to count the experimental results, you can call the statistical_fl_results(file_path, tag_root_dir) function in the statistics.py file, where tag_root_dir is the error message we marked. Before you count the experimental results, please make sure that the first two worksheets in the excel file are blank.
