## AI overview

This developer article explains how engineers debug bugs reported by developers, QA, and users. It compares the role of unit tests and end-to-end tests, then describes the greater difficulty of diagnosing vague user-reported symptoms.

## Source excerpt

As engineers, we deal with bugs every day. Finding the root cause and delivering the right fix is one of our most essential -- and satisfying -- skills. In this post, I want to walk through different types of issues we face and how we typically debug them. Most importantly, I'll share my favorite and most challenging method: data-driven debugging. Let's break it down by who reports the issue and how it's discovered.
