QTL – Testing & CI/CD

Context: Global pharmaceutical company with 2,000+ clinical studies requiring reliable, production‑grade R packages for QTL fraud detection.

Challenge: The QTL R packages needed to be thoroughly tested and automatically deployed to ensure stability, reproducibility, and audit‑readiness across 35,000+ sites.

Solution: Established a robust testing and CI/CD pipeline using:

• devtools for package development and validation
• shinytest2 and testthat for unit and integration tests
• GitHub Actions for automated testing and deployment on every commit

Outcome: Achieved a fully automated CI/CD pipeline that ensures all QTL packages are tested, validated, and deployed consistently, reducing manual review time and improving reliability.
