Becoming a Rockstar SRE

By: Jeremy Proffitt, Rod Anami

Overview of this book

Site reliability engineering is all about continuous improvement, finding the balance between business and product demands while working within technological limitations to drive higher revenue. But quantifying and understanding reliability, handling resources, and meeting developer requirements can sometimes be overwhelming. With a focus on reliability from an infrastructure and coding perspective, Becoming a Rockstar SRE brings forth the site reliability engineer (SRE) persona using real-world examples. This book will acquaint you the role of an SRE, followed by the why and how of site reliability engineering. It walks you through the jobs of an SRE, from the automation of CI/CD pipelines and reducing toil to reliability best practices. You’ll learn what creates bad code and how to circumvent it with reliable design and patterns. The book also guides you through interacting and negotiating with businesses and vendors on various technical matters and exploring observability, outages, and why and how to craft an excellent runbook. Finally, you’ll learn how to elevate your site reliability engineering career, including certifications and interview tips and questions. By the end of this book, you’ll be able to identify and measure reliability, reduce downtime, troubleshoot outages, and enhance productivity to become a true rockstar SRE!

Using test automation frameworks

Good software testing doesn’t necessarily imply a high-quality and reliable system, but no testing will most likely result in a flawed application with bugs. Despite that, companies that adopt DevOps and CI/CD pipelines have a clear requirement for automated tests, and they cannot afford long manual testing cycles that clog up their pipeline (and delay the release process).

Test automation frameworks aid developers and testers with good practices, rules, and guidelines that they follow pragmatically to achieve automated testing in software development. These frameworks establish how to write automation test scripts and manage test datasets. Within software engineering, we have the following types of test automation frameworks:

  • Linear scripting
  • Modular testing
  • Library architecture scripting
  • Data-driven testing
  • Keyword-driven testing
  • Hybrid testing
  • Behavior-driven development (BDD) testing

Each type of...
