Serverless application development is fabulous…but if you don’t have a CI/CD pipeline with a strong foundation of test automation, you’ll likely fail. In this session, MongoDB Developer Advocate Lauren Schaefer will walk you through the process of crafting test automation and DevOps pipelines for serverless apps that are built on MongoDB Realm. Then, she’ll jump into the always-terrifying-for-the-presenter live demo so you can see how this all works in a very practical way. She’ll make some changes to her codebase, update her automated tests, and push her code changes. You’ll watch as the various pieces of the pipeline fail and (hopefully) succeed. You’ll walk away from this session equipped to build test automation and DevOps pipelines for your serverless apps.
