legacy code maintenance

What it does

Guides safe, incremental changes to untested code by establishing tests and breaking dependencies before modifying behavior.

Use when changing or testing legacy or untested code, especially when dependencies obstruct a test harness.

Give it a change in an untested project; it identifies test points, establishes coverage, and makes the change incrementally.
