Behaviour-Driven Development for Testers and Developers
Your customers want rock-solid, bug-free software that does exactly what they expect it to do. Yet they can't always articulate their ideas clearly enough for you to turn them into code. You need Cucumber: a testing, communication, and requirements tool-all rolled into one. All the code in this book more » is updated for Cucumber 2.4, Rails 5, and RSpec 3.5. Express your customers' wild ideas as a set of clear, executable specifications that everyone on the team can read. Feed those examples into Cucumber and let it guide your development. Build just the right code to keep your customers happy. You can use Cucumber to test almost any system or any platform. Get started by using the core features of Cucumber and working with Cucumber's Gherkin DSL to describe-in plain language-the behavior your customers want from the system. Then write Ruby code that interprets those plain-language specifications and checks them against your application. Next, consolidate the knowledge you've gained with a worked example, where you'll learn more advanced Cucumber techniques, test asynchronous systems, and test systems that use a database. Recipes highlight some of the most difficult and commonly seen situations the authors have helped teams solve. With these patterns and techniques, test Ajax-heavy web applications with Capybara and Selenium, REST web services, Ruby on Rails applications, command-line applications, legacy applications, and more. Written by the creator of Cucumber and the co-founders of Cucumber Ltd., this authoritative guide will give you and your team all the knowledge you need to start using Cucumber with confidence. What You Need: Windows, Mac OS X (with XCode) or Linux, Ruby 1.9.2 and upwards, Cucumber 2.4, Rails 5, and RSpec 3.5 « less
Building Quality into Software
To build high-quality software, you need to write testable code. That's harder than it seems: it requires insights drawn from arenas ranging from software craftsmanship to unit testing, refactoring to test-driven development. Most programming books either discuss testing only briefly, or drill down on more » just one or two techniques, with little guidance on how to systematically verify code. Most testing books, on the other hand, focus on a specific testing process, without showing how to write software that can be easily and systematically tested. In Developer Testing, leading software engineering consultant Alexander Tarnowski strikes an optimal balance, integrating insights from multiple disciplines to help frustrated practitioners get better results. Drawing on his extensive experience as a mentor and trainer, he offers insights that help you accelerate through the typical software assurance learning curve, so you can progress far more rapidly. Tarnowski organizes his insights into "chunks" to help you quickly absorb key concepts, and focuses on technology-agnostic approaches you can keep using with any new language, platform, or toolset. Along the way, he answers many questions development teams often ask about testing, including: * What makes code testable? What makes it hard to test? * When have I done enough testing on a piece of code? * How many unit tests do I need to write? * Exactly what should my test verify? * How do I transform monolithic legacy code into manageable pieces I can test? * What's the best way to structure my tests? The first guide to cover testing mindset, techniques, and applications from the developer's perspective, Developer Testing will help developers get what they really want: better code. « less

*** Key Features *** * Explore the concept of testability and how to implement tests that deliver the most value * Maximize the quality of your Ruby code through a wide variety of tests * Master the real-world tradeoffs of testing through detailed examples supported by in-depth discussion *** more » Book Description *** This book will teach you how to use RSpec to write high-value tests for real-world code. We start with the key concepts of the unit and testability, followed by hands-on exploration of key features. From the beginning, we learn how to integrate tests into the overall development process to help create high-quality code, avoiding the dangers of testing for its own sake. We build up sample applications and their corresponding tests step by step, from simple beginnings to more sophisticated versions that include databases and external web services. We devote three chapters to web applications with rich JavaScript user interfaces, building one from the ground up using behavior-driven development (BDD) and test-driven development (TDD). The code examples are detailed enough to be realistic while simple enough to be easily understood. Testing concepts, development methodologies, and engineering tradeoffs are discussed in detail as they arise. This approach is designed to foster the reader's ability to make well-informed decisions on their own. *** What you will learn *** * Identify a unit of software for the purposes of testing * Manage test states with hooks, fixtures, and mocks * Handle external web services in tests using various techniques * Configure RSpec flexibly and cleanly using support code and environment variables * Interact with rich web apps in tests using Capybara * Build the right feature with behavior-driven development * Customize matchers and failure messages * Verify correct development and production environments *** About the Author *** Mani Tadayon first learned to program as a shy 7th grader on an Apple IIe using BASIC. He went on to learn Pascal, C++, Java, JavaScript, Visual Basic, and PHP before becoming a Ruby developer in 2008.
