Let’s learn by example.

This tutorial will walk you through the basic concepts and features of Codecov. We will do so by building out a server-side calculator that calls an API to process any calculations and returns back the computed result.

The tutorial is built using python3 (Flask) on the backend and javascript (Expressjs) on the frontend. We will be using GitLabCI as the CI/CD. We will assume some familiarity with code coverage as well as an existing GitLab account.

Starter code can be found on our demo repository.
