This is the replication package for the paper: A Large Empirical Study on Blob Blueprint in Technology-Agnostic Infrastructure Code.

How to reproduce

• (Optional) Create a virtual environment:

source venv/bin/activate

• Install dependencies and run the program:

pip install -r requirements.txt
python main.py

Follow the instructions in the terminal to run the desired experiment and plot graphs.

Additional information

• data/tosca_repositories.csv is a static file containing the collected TOSCA repositories.

• data/tosca_blueprints.csv is generated running python clustering/collect_blueprints.py. That script collects the raw urls of blueprints in the latest release of every repository. Use this command if you want to collect updated blueprints.

• data/metrics.csv is generated running python clustering/collect_metrics.py. That script uses the previous csv to access the raw content of every blueprint and extract the metrics used in this study.

• data/validation.csv is a static file containing the validation results among the assessors.

• data/EXPLORATORY_ANALYSIS.md/ contains results for RQ1.

• data/performance/ and STATISTICAL_ANALYSIS.md contains results of the empirical evaluation for RQ2.

• data/feature-selection/ contains results of the stepwise forward selection for RQ3.
