5+ curated questions with the same answer shape every time: quick recap, deep dive, pitfalls, and follow-ups. Coverage includes byebug and pry, rails console tricks, reading stack traces, rubocop basics, and more.
Suggested path
Topics follow a teaching order. Each answer ends with a clear Next question control so you can move forward without hunting the list.
Ruby debugging questions test whether a developer can turn a failure into evidence and a durable fix. This module covers execution control with Byebug and Pry, the current Rails debugger context, common runtime exception contracts, safe Rails console investigation, ordered backtrace reading, and team use of RuboCop. Every lesson begins with the failed assumption, uses a concrete example, distinguishes observation from mutation, and ends with a reproducible test or review boundary rather than a temporary debugging trick.
