C++ Quality Gates: What to Check Before Merging Code

A practical guide to the CI checks that help keep broken C++ code out of main.

Green tests do not always mean safe code.

C++ code can pass tests and still hide undefined behavior, memory issues,
data races, formatting noise, or architectural problems.

That is why a pull request needs a quality gate:
a fast and stable set of checks that runs before code reaches main.

What this guide helps you do

  • choose which checks your CI should run before merging code
  • generate useful coverage reports
  • enable sanitizers
  • integrate clang-tidy
  • enforce formatting with clang-format
  • understand where code review still matters
