I feel like you don't need a deep dive for what you're describing. Start step by step. Before building on Github Actions, build locally. See if you can build and tag and image with the git SHA. Then run your automated test command against the image/container. Then see if you can write a github action doing exactly what you did locally. Random blog posts have been more helpful in my experience vs youtube videos.
