Overview of this book

DevOps is a practical field that focuses on delivering business value as efficiently as possible. DevOps encompasses all the flows from code through testing environments to production environments. It stresses the cooperation between different roles, and how they can work together more closely, as the roots of the word imply—Development and Operations. After a quick refresher to DevOps and continuous delivery, we quickly move on to looking at how DevOps affects architecture. You'll create a sample enterprise Java application that you’ll continue to work with through the remaining chapters. Following this, we explore various code storage and build server options. You will then learn how to perform code testing with a few tools and deploy your test successfully. Next, you will learn how to monitor code for any anomalies and make sure it’s running properly. Finally, you will discover how to handle logs and keep track of the issues that affect processes

Chapter 6. Testing the Code

If we are going to release our code early and often, we ought to be confident of its quality. Therefore, we need automated regression testing.

In this chapter, some frameworks for software testing are explored, such as JUnit for unit testing and Selenium for web frontend testing. We will also find out how these tests are run in our Continuous Integration server, Jenkins, thus forming the first part of our Continuous Delivery pipeline.

Testing is very important for software quality, and it's a very large subject in itself.

We will concern ourselves with these topics in this chapter:

  • How to make manual testing easier and less error prone
  • Various types of testing, such as unit testing, and how to perform them in practice
  • Automated system integration testing

We already had a look at how to accumulate test data with Sonar and Jenkins in the previous chapter, and we will continue to delve deeper into this subject.
