How Rust Is Tested

Brian Anderson (via Hacker News):

Rust has a strict continuous integration system that runs a great number of tests on every pull request, basically guaranteeing that the Rust master branch always works; which is crucial because Rust releases nightly builds every night, and stable builds every six weeks. And Rust further tests every release against its entire open source library ecosystem.

I’ve always admired well-tested software projects, like SQLite, and aim to place Rust among the pantheon of the best. This document then, is a catalog of all the ways we test Rust. I hope it provides insight into what it takes to deliver a production-quality programming language, a hint at the wide variety of techniques employed in software validation, and that it reinforces your confidence in Rust’s reliability.
