Shaky to solid a test based approach to legacy code
summary
Claims a repeatable way to turn brittle legacy code into maintainable code by first writing characterization tests to lock down current behavior, then adding unit and integration tests with test doubles and a CI gate that runs on every PR. Workflow identifies the smallest risky modules, builds test harnesses around them, and lets teams refactor confidently; the deliverable is a growing automated test suite and CI pipeline that prevents regressions and enables safer deployments.
