CI/CD with Mercurial is a different beast. Most guides focus on Git, drowning you in tools that won’t play nicely with your repository. But Mercurial still powers serious projects, and it deserves a fast, modern, automated pipeline as much as any Git-based workflow.
The first step is making sure your CI/CD process understands Mercurial from the ground up. That means connecting to your repo without fragile wrappers, keeping changesets atomic, and ensuring branch merges don’t corrupt build artifacts. Mercurial’s branching, with named branches and bookmarks, gives you flexibility—your pipeline should treat them as first-class citizens.
A powerful CI/CD setup for Mercurial should do more than run automated tests. It should lint code, build artifacts, run integration checks, and deploy without waiting for human intervention. Build triggers can be tied to pushes, pull requests, or even tag creation for releases. Good pipelines parallelize jobs, cache dependencies, and break when something breaks—fast and visibly.
