Mastering Google Apps Script CI/CD: Seamless GitHub Actions Integration with gas-fakes

Abstract Discover how to seamlessly integrate Google Workspace with GitHub Actions using the gas-fakes library. This guide demonstrates running Google Apps Script locally and within CI/CD pipelines without deploying Web Apps. Automate workflows, secure credentials, and effortlessly interact with Google Drive and Sheets directly from your repository. Introduction Google Apps Script (GAS) is a powerful low-code platform that enables developers to integrate, automate, and extend Google Workspace with ease.
