IBM/Issue-Test-Localizer: This repository is for Issue-Test-Localizer. An approach for localizing tests from issue descriptions

Given as input an issue description and the files in a Python repo, return as output a selected subset of relevant regression tests existing in the repo.

This is an approach to select regression tests to assist the process of solving software development problems.

• Localization: We first localize the fault to specific files, then to suspicious functions.
• Test Selection: For each suspicious function, we identify all tests that exercise it.
• Test Minimization: The selected tests are further reduced to a minimal set of regression tests needed to cover the relevant functions.

1. Environment Setup

git clone https://github.ibm.com/tfahmed/Regression-Test-Selection
cd Regression-Test-Selection

python3.11 -m venv selection_venv
source selection_venv/bin/activate
pip install -r requirements.txt

1. API Key Setup

export OPENAI_API_KEY={Your_Key}
export MODEL_SERVING_URL={Base_URL} # URL of the model serving endpoint

1. Suspicious Function Localization

bash -x src/get_suspicious_funcs.sh [dataset] [model] [log_dir]

After the script completes, you can find:

• Per-instance logs in log_dir.
• Per-instance results in $log_dir/${model}_results (each as a JSON file).
• The aggregated results for all instances in $log_dir/${model}_combined.json.

1. Regression Test Selection and Minimization

python3 minimization.py [suspicious_func_json] [result_json]

• [suspicious_func_json] should be the $log_dir/${model}_combined.json file generated in the previous step.
• [result_json] is the output path where you want to save the minimized results. Each entry in the output JSON will correspond to an instance_id, with the selected regression tests listed as its value.
