A comprehensive, hands-on guide on unit testing framework for Java programming language About This Book - In-depth coverage of Jupiter, the new programming and extension model provided by JUnit 5 - Integration of JUnit 5 with other frameworks such as Mockito, Spring, Selenium, Cucumber, and Docker - Best practices for writing meaningful Jupiter test cases Who This Book Is For This book is for Java software engineers and testers. If you are a Java developer who is keen on improving the quality of your code and building world class applications then this book is for you. Prior experience of the concepts of automated testing will be helpful. What You Will Learn - The importance of software testing and its impact on software quality - The options available for testing Java applications - The architecture, features and extension model of JUnit 5 - Writing test cases using the Jupiter programming model - How to use the latest and advanced features of JUnit 5 - Integrating JUnit 5 with existing third-party frameworks - Best practices for writing meaningful JUnit 5 test cases - Managing software testing activities in a living software project In Detail When building an application it is of utmost importance to have clean code, a productive environment and efficient systems in place. Having automated unit testing in place helps developers to achieve these goals. The JUnit testing framework is a popular choice among Java developers and has recently released a major version update with JUnit 5. This book shows you how to make use of the power of JUnit 5 to write better software. The book begins with an introduction to software quality and software testing. After that, you will see an in-depth analysis of all the features of Jupiter, the new programming and extension model provided by JUnit 5. You will learn how to integrate JUnit 5 with other frameworks such as Mockito, Spring, Selenium, Cucumber, and Docker. After the technical features of JUnit 5, the final part of this book will train you for the daily work of a software tester. You will learn best practices for writing meaningful tests. Finally, you will learn how software testing fits into the overall software development process, and sits alongside continuous integration, defect tracking, and test reporting. Style and approach The book offers definitive and comprehensive coverage of all the Unit testing concepts with JUnit and its features using several real world examples so that readers can put their learning to practice almost immediately. This book is structured in three parts: 1. Software testing foundations (software quality and Java testing) 2. JUnit 5 in depth (programming and extension model of JUnit 5) 3. Software testing in practice (how to write and manage JUnit 5 tests)
Books published by Packtpub are often a hit or miss. This was a hit.
I bought this one in the new year $5 sale with a ton of other books for summer reading. This one is worth the full price.
It has a bit stuffing on the beginning explaining on testing and test standards. It did not bother me. I think it is a valuable book for people new to the field. I think the. book is suitable for classroom use. At the end it also has some extra stuffing on integrating other tooling that is remotely related to Junit.
The book explains Junit 5 and it's benefits over version 3 and 4 very well. It has a good explanation of the differences in handy tables. It also explains compatibility plugins. However it does not mention Junit 4.13. IMHO, moving to that from 4.12 and then to 5 is also a viable strategy in some cases.
Interesting where the sections on naming tests human readable via @Display and tagging to group tests. Also the section on writing Extensions instead of Rules was interesting. The buildin matchers make Hamcrest no longer needed for many situations. Also the section on all different kinds of parameterized tests was worth reading.
In later chapters it goes into integrating Mockito, Hamcrest and more . I especially liked the chapters on REST API testing and using Docker. However only read these briefly because I was more interested in migration from 3 and 4 and the core benefits.
The writing style is pleasant and the examples are good too.
Buy if you need/want to migrate tests or want to start learning on unit testing with Junit 5.
