The Pragmatic Programmers classic is back! Freshly updated for modern software development, Pragmatic Unit Testing in Java 8 With JUnit teaches you how to write and run easily maintained unit tests in JUnit with confidence. You''ll learn mnemonics to help you know what tests to write, how to remember all the boundary conditions, and what the qualities of a good test are. You''ll see how unit tests can pay off by allowing you to keep your system code clean, and you''ll learn how to handle the stuff that seems too tough to test.

Pragmatic Unit Testing in Java 8 With JUnit steps you through all the important unit testing topics. If you''ve never written a unit test, you''ll see screen shots from Eclipse, IntelliJ IDEA, and NetBeans that will help you get past the hard part--getting set up and started.

Once past the basics, you''ll learn why you want to write unit tests and how to effectively use JUnit. But the meaty part of the book is its collected unit testing wisdom from people who''ve been there, done that on production systems for at least 15 years: veteran author and developer Jeff Langr, building on the wisdom of Pragmatic Programmers Andy Hunt and Dave Thomas. You''ll learn:

You won''t just learn about unit testing in theory--you''ll work through numerous code examples. When it comes to programming, hands-on is the only way to learn!

The classic Pragmatic Unit Testing with Java in JUnit returns for a third edition, streamlined and rewritten with updated and more accessible code examples. In this edition, you''ll learn how to create concise, maintainable unit tests with confidence. New chapters provide a foundation of examples for testing common concepts, and guidance on incorporating modern AI tools into your development and testing. Updated topics include improving test quality via development mnemonics, increasing ROI through test and production code refactoring, and using tests to drive development.

Pragmatic Unit Testing in Java with JUnit steps you through all the important unit testing topics.

If you''ve never written a unit test, you''ll be hand-held through the hard part - getting set up and started. Once past the basics, you''ll see numerous examples in order to start understanding what tests for common code concepts look like. You''ll then learn how to effectively use the essential features of JUnit, the predominant tool for writing and executing unit tests in Java.

You''ll gain the combined wisdom of Jeff Langr and original authors Andy Hunt and Dave Thomas, providing decades of unit testing experience on real production systems. You''ll learn how to:

You won''t just learn about unit testing in theory - you''ll learn about "real" unit testing the Pragmatic way, by working through numerous code examples.

What You Need:

You''ll need the Java SDK (Software Development Kit) version 21 or higher to work through the examples in the book. You''ll also want an IDE (Integrated Development Environment) in which to build code. While most of the book doesn''t assume use of any specific IDE, you''ll find a number of "getting started" screen shots to help you if you''re using IntelliJ IDEA.
