Development Methodologies

Software development practices and principles for building high-quality, maintainable software — from testing strategies to delivery pipelines.

Testing Practices

Write a failing test first, then write the minimum code to pass it, then refactor — the red-green-refactor cycle for confident code.

Extend TDD with natural-language specifications — Given/When/Then scenarios that bridge the gap between business and development.

Generate random inputs to verify properties that should always hold — finds edge cases that example-based tests miss.

Merge code changes frequently into a shared branch with automated builds and tests — catch integration issues early.

Automate the release pipeline so every change is production-ready — continuous delivery requires manual approval, deployment is fully automated.

All developers commit to a single shared branch (trunk/main) with short-lived feature branches — enables continuous integration and fast feedback.

Decouple deployment from release by wrapping features in toggles — enables trunk-based development, A/B testing, and gradual rollouts.
