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: - Craft your code to make unit testing easier in the first place - Craft your unit tests to minimize your maintenance effort - Use unit tests to support keeping your system clean through refactoring - Refactor toward a design that will create the highest possible ROI - Test the tough stuff, including code that must be mocked - Remember what''s important when writing unit tests - Help your team reap and sustain the benefits of unit testing - Use AI tooling as part of a development process that incorporates unit testing 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.

Property-Based Testing with PropEr, Erlang, and Eliixir - Fred Hebert - Bog - The Pragmatic Programmers - Plusbog.dk

Property-Based Testing with PropEr, Erlang, and Eliixir - Fred Hebert - Bog - The Pragmatic Programmers - Plusbog.dk

Property-based testing helps you create better, more solid tests with little code. By using the PropEr framework in both Erlang and Elixir, this book teaches you how to automatically generate test cases, test stateful programs, and change how you design your software for more principled and reliable approaches. You will be able to better explore the problem space, validate the assumptions you make when coming up with program behavior, and expose unexpected weaknesses in your design. PropEr will even show you how to reproduce the bugs it found. With this book, you will be writing efficient property-based tests in no time. Most tests only demonstrate that the code behaves how the developer expected it to behave, and therefore carry the same blind spots as their authors when special conditions or edge cases show up. Learn how to see things differently with property tests written in PropEr. Start with the basics of property tests, such as writing stateless properties, and using the default generators to generate test cases automatically. More importantly, learn how to think in properties. Improve your properties, write custom data generators, and discover what your code can or cannot do. Learn when to use property tests and when to stick with example tests with real-world sample projects. Explore various testing approaches to find the one that''s best for your code. Shrink failing test cases to their simpler expression to highlight exactly what breaks in your code, and generate highly relevant data through targeted properties. Uncover the trickiest bugs you can think of with nearly no code at all with two special types of properties based on state transitions and finite state machines. Write Erlang and Elixir properties that generate the most effective tests you''ll see, whether they are unit tests or complex integration and system tests. What You Need - Basic knowledge of Erlang, optionally Elixir - For Erlang tests: Erlang/OTP = 20.0, with Rebar = 3.4.0 - For Elixir tests: Erlang/OTP = 20.0, Elixir = 1.5.0

Agile Web Development with Rails 7.2 - Dave Thomas - Bog - The Pragmatic Programmers - Plusbog.dk

Rails 7.2 completely redefined what it means to produce fantastic user experiences and provides a way to achieve all the benefits of single-page applications - a fraction of the complexity. Rails 7.2 integrated the Hotwire frameworks of Stimulus and Turbo directly as the new defaults, together with that hot newness of import maps. The result is a toolkit so powerful that it allows a single individual to create modern applications upon which they can build a competitive business. The way it used to be. Ruby on Rails helps you produce high-quality, beautiful-looking web applications quickly - you concentrate on creating the application, and Rails takes care of the details. Rails 7.2 brings many improvements, and this edition is updated to cover the new features and changes in best practices. We start with a step-by-step walkthrough of building a real application, and in-depth chapters look at the built-in Rails features. Follow along with an extended tutorial as you write a web-based store application. Eliminate tedious configuration and housekeeping, seamlessly incorporate JavaScript, send and receive emails, manage background jobs with ActiveJob, and build real-time features using WebSockets and ActionCable. Test your applications as you write them using the built-in unit, integration, and system testing frameworks, internationalize your applications, and deploy your applications easily and securely. Rails 1.0 was released in December 2005. This book was there from the start, and didn''t just evolve alongside Rails, it evolved with Rails. It has been developed in consultation with the Rails core team. In fact, Rails itself is tested against the code in this book. What You Need: All you need is a Windows, Mac OS X, or Linux machine to do development on. This book will take you through the steps to install Rails and its dependencies. If you aren''t familiar with the Ruby programming language, this book contains a chapter that covers the basics necessary to understand the material in the book.
