From local scripts to a world-ready backend: CI/CD, testing, and coverage in SparkTrace
In recent weeks, we transformed the SparkTrace backend project into a reproducible, test-oriented system with CI/CD integration, prepared for international technical interviews and scalable deployments.
Modular architecture and refactor
I reorganized the Django commands into a clear structure under productos/management/commands/, decoupled the API integration logic, CSV loading, and Spark job execution, and refactored the settings and .gitignore for cross-platform compatibility and cloud deployments.
Automated testing and coverage
I built a complete test suite with pytest and pytest-django, validated edge cases with JSON fixtures that simulate real API responses, and achieved full coverage in critical modules such as the CSV loader, API integration, and custom exceptions. The testing strategy is documented for audit in the project's bilingual README.
CI/CD integration with GitHub Actions
I configured workflows to run tests and measure coverage on every push and pull request, managed secrets such as SECRET_KEY and CODECOV_TOKEN securely in GitHub, integrated Codecov for visual coverage reports, and added status badges to the README to improve traceability and trust in the pipeline.
Professional presentation and portfolio
I updated the README with technical branding, published updates on LinkedIn to highlight reproducibility and traceability, and have a live portfolio at nicolasandrescl.pythonanywhere.com showcasing the SparkTrace project as a technical showcase.
