Writing Solid Ruby Code
summary
Argues that the single best way to raise confidence is repeatable tests and shows concrete tactics: run mutation testing with Heckle to find weak specs, fuzz external inputs, and treat tests as readable specifications; use interactive exploration with pry and the Ruby debugger to inspect state during failures; measure cyclomatic complexity to find the 79+ hot methods; fortify controllers by scoping DB/URL-derived queries to current_user; and ship a tiny helper, readable specs using rspec-given, for clearer examples like the Gilded Rose kata.
