Hands-on Test-Driven Development
Learn to properly test Ruby and Ruby on Rails applications by first writing failing tests, and then by implementing application code to make the failing tests pass. This book will teach you how to employ test-driven development (TDD) using RSpec while building a blog from start to finish. By the end of the book, you will be ready to deploy their fully tested blog to their own production web server using the latest versions of Ruby 3 and Ruby on Rails 7. The biggest challenge with learning and becoming comfortable with test-driven development is that software engineers often cannot imagine what writing a failing test looks like in practice. They write their implementation code first, and only then think about writing tests around their implementation code. This leads to tests that pass by accident, or tests that do not actually test anything. This book will give you the confidence to write tests in the RSpec domain-specific language. You will see your tests fail "properly" before proceeding with writing any implementation code to get them to pass. This book covers the latest techniques for writing RSpec tests, including "system" specs, and the often overlooked "view" specs, and how to integrate RSpec with other tools like Capybara, headless Chrome, and the new web driver gem. It also covers FactoryBot for mock test data and offers experienced advice on how to avoid creating tests that fail randomly. What You Will Learn Build a blog application from start to finish using test driven development Install and explore popular tools used in professional Ruby software engineering Evaluate the benefits of effective testing in RSpec Explore Capistrano for advanced user interface testing Who Is This Book For Beginner to intermediate Ruby software engineers who are interested in learning to use TDD with RSpec to test and build web applications using Ruby on Rails. Readers should have some basic experience with Ruby and Ruby on Rails and have read the "Getting Started with Rails" guide, or something similar.
Hands-On Test-Driven Development with Java and Spring
Learn the TDD approach to better and faster development About This Video Grasp the fundamentals of Test-Driven Development and understand how it works alongside software development. Gain the necessary skills to refine and optimize your code while getting started with the TDD approach Enhance your skills by developing better software quickly and find hidden loopholes by adapting the TDD approach as part of the development life cycle In Detail Software development is permeating the world and this development has reached unparalleled levels today, thanks to rapid advancements in technology. The need for software testing has also become so critical that we need to shift the way we develop software. Test-Driven Development (TDD) is at the forefront of how we test software from the moment we start developing it. This course is designed to make sure that you can quickly learn and adapt TDD techniques in your projects to take full advantage of what TDD has to offer. With TDD, testing software is embedded within the development cycle, allowing a constant testing feedback loop and thereby giving you the confidence to achieve optimal results for your software. We quickly start TDD implementation with Java, and then deploy TDD with Spring. We also learn how things work under-the-hood by exploring how Spring and TDD work internally. Lastly, we apply integration testing to all implementations created in the course to get a taste of how two components interact with each other. By the end of this course, you'll have gained the skills you need to develop software using the TDD approach and you'll get higher-quality and faster results in no time!
Test Driven
In test driven development, you first write an executable test ofwhat your application code must do. Only then do you write thecode itself and, with the test spurring you on, you improve yourdesign. In acceptance test driven development (ATDD), you usethe same technique to implement product features, benefiting fromiterative development, rapid feedback cycles, and better-definedrequirements. TDD and its supporting tools and techniques leadto better software faster. Test Driven brings under one cover practical TDD techniquesdistilled from several years of community experience. With examplesin Java and the Java EE environment, it explores both the techniquesand the mindset of TDD and ATDD. It uses carefully chosen examplesto illustrate TDD tools and design patterns, not in the abstractbut concretely in the context of the technologies you face at work.It is accessible to TDD beginners, and it offers effective and less wellknown techniques to older TDD hands. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.
