Overview of this book

Developing applications for the cloud involves changing development methodologies and procedures. Continuous integration and continuous deployment (CI/CD) processes are a must today, but are often difficult to implement and adopt. Azure DevOps is a Microsoft Azure cloud service that enhances your application development life cycle and enables DevOps capabilities. Starting with a comprehensive product overview, this book helps you to understand Azure DevOps and apply DevOps techniques to your development projects. You'll find out how to adopt DevOps techniques for your development processes by using built-in Azure DevOps tools. Throughout the course of this book, you'll also discover how to manage a project with the help of project management techniques such as Agile and Scrum, and then progress toward development aspects such as source code management, build pipelines, code testing and artifacts, release pipelines, and GitHub integration. As you learn how to implement DevOps practices, this book will also provide you with real-world examples and scenarios of DevOps adoption. By the end of this DevOps book, you will have learned how to adopt and implement Azure DevOps features in your real-world development processes.

Introduction to code coverage testing

With code coverage testing, you can measure what source code for an application is going to be tested. Code coverage testing measures how many lines, blocks, and classes are executed while automated tests, such as unit tests, are running.

The more code that's tested, the more confident teams can be about their code changes. By reviewing the outcome of the code coverage tests, teams can identify what code is not covered by these tests. This information is very helpful as it reduces test debt over time.

Azure DevOps supports code coverage testing from the build pipeline. The Test Assemblies task allows us to collect code coverage testing results. There is also a separate task, called Publish Code Coverage Results, that can also publish these results. This task offers out-of-the-box support for popular coverage results formats such as Cobertura and JaCoCo.

Important Note

Cobertura and JaCoCo are both Java tools that calculate the...
