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.

xUnit in general and JUnit in particular

You need something that runs your tests. JUnit is a framework that lets you define unit tests in your Java code and run them.

JUnit belongs to a family of testing frameworks collectively called xUnit. This is the grandfather of this family and was designed by Kent Beck in 1998 for the Smalltalk language.

While JUnit is specific to Java, the ideas are sufficiently generic for ports to have been made in, for instance, C#. The corresponding test framework for C# is called, somewhat unimaginatively, NUnit. The N is derived from .NET, the name of the Microsoft software platform.

We need some of the following nomenclature before carrying on. The nomenclature is not specific to JUnit, but we will use JUnit as an example to make it easier to relate to the definitions:

  • Test runner: A test runner runs tests that are defined by an xUnit framework...
