Treffer: Revisiting Machine Learning based Test Case Prioritization for Continuous Integration

This repository contains a replication package for a research paper submitted to the 45th International Conference on Software Engineering (https://conf.researchr.org/home/icse-2023). We provide our code, data, and result for the ease of replicating our experiments. Code In the collect_data subdirectory, scripts for constructing TCP datasets are provided. We do dependency analysis using Understand (https://www.scitools.com/), so please download the related tools in advance. In the rl subdirectory, we provide the python implementation for algorithms RL, COLEMAN, PPO2-PO, ACER-PA, PPO1-LI. In the supervised_learning subdirectory, we provide implementations for MART, RankNet, RankBoost, CA, L-MART, which mainly rely on Ranklib (https://sourceforge.net/p/lemur/wiki/RankLib/.). We also provide implementation for DeepOrder. Data The origin subdirectory contains the original datasets collected from github using our scripts, including 11 projects. The smote subdirectory contains the datasets pre-processed by SMOTE. Result Results for RQ1, RQ2, RQ3, and threats to validity are provided in the corresponding subdirectories. Scripts for plotting figures are also provided.
