This tutorial explores how to automate testing in Rust projects through a continuous integration pipeline using CircleCI. Highlighting Rust's performance and reliability, especially when paired with WebAssembly and Node.js, the tutorial provides a step-by-step guide to creating a simple Rust CLI application that prompts for a user's name and returns a greeting. It explains how to write and run unit tests for the application using Rust's built-in testing framework and details setting up automated tests that trigger upon code updates pushed to a GitHub repository. The tutorial concludes by encouraging users to further explore continuous deployment for Rust applications, emphasizing the increased efficiency and value Rust can bring to development teams.
