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.

A complete test automation scenario

We have looked at a number of different ways of working with test automation. Assembling the pieces into a cohesive whole can be daunting.

In this section, we will have a look at a complete test automation example, continuing from the user database web application for our organization, Matangle.

You can find the source code in the accompanying source code bundle for the book.

The application consists of the following layers:

  • A web frontend
  • A JSON/REST service interface
  • An application backend layer
  • A database layer

The test code will work through the following phases during execution:

  1. Unit testing of the backend code.
  2. Functional testing of the web frontend, performed with the Selenium web testing framework.
  3. Functional testing of the JSON/REST interface, executed with SoapUI.

All the tests are run in sequence, and when all of them succeed...
