Practical DevOps - Second Edition

By: joakim verona

Overview of this book

DevOps is a practical field that focuses on delivering business value as efficiently as possible. DevOps encompasses all code workflows from testing environments to production environments. It stresses cooperation between different roles, and how they can work together more closely, as the roots of the word imply—Development and Operations. Practical DevOps begins with a quick refresher on DevOps and continuous delivery and quickly moves on to show you how DevOps affects software architectures. You'll create a sample enterprise Java application that you’'ll continue to work with through the remaining chapters. Following this, you will explore various code storage and build server options. You will then learn how to test your code with a few tools and deploy your test successfully. In addition to this, you will also see how to monitor code for any anomalies and make sure that it runs as expected. Finally, you will discover how to handle logs and keep track of the issues that affect different processes. By the end of the book, you will be familiar with all the tools needed to deploy, integrate, and deliver efficiently with DevOps.

Pros and cons with test automation

When you talk with people, most are enthusiastic about the prospect of test automation. Imagine all the benefits that await us with it:

  • Higher software quality
  • Higher confidence that the software releases we make will work as intended
  • Less of the monotonous tedium of laborious manual testing

All very good and desirable things!

In practice, though, if you spend time with different organizations with complex multi-tiered products, you will notice people talking about test automation, but you will also notice a suspicious absence of test automation in practice. Why is that?

If you just compile programs and deploy them once they pass compilation, you will likely be in for a bad experience. Software testing is completely necessary for a program to work reliably in the real world. Manual testing is too slow to achieve CD. So, we need test automation...
