And much more, including Espresso tests, UI tests, code coverage and refactoring. One thing you can count on: after reading this book, you'll be prepared to take advantage of Android Test-Driven Development in your own apps!

Quite simply, test-driven development is meant to eliminate fear in application development. While some fear is healthy (often viewed as a conscience that tells programmers to "be careful!"), the author believes that byproducts of fear include tentative, grumpy, and uncommunicative programmers who are unable to absorb constructive criticism. When programming teams buy into TDD, they immediately see positive results. They eliminate the fear involved in their jobs, and are better equipped to tackle the difficult challenges that face them. TDD eliminates tentative traits, it teaches programmers to communicate, and it encourages team members to seek out criticism However, even the author admits that grumpiness must be worked out individually! In short, the premise behind TDD is that code should be continually tested and refactored. Kent Beck teaches programmers by example, so they can painlessly and dramatically increase the quality of their work.

Hands-on guidance to creating great test-driven development practice Test-driven development (TDD) practice helps developers recognize a well-designed application, and encourages writing a test before writing the functionality that needs to be implemented. This hands-on guide provides invaluable insight for creating successful test-driven development processes. With source code and examples featured in both C# and .NET, the book walks you through the TDD methodology and shows how it is applied to a real-world application. You’ll witness the application built from scratch and details each step that is involved in the development, as well as any problems that were encountered and the solutions that were applied. Clarifies the motivation behind test-driven development (TDD), what it is, and how it works Reviews the various steps involved in developing an application and the testing that is involved prior to implementing the functionality Discusses unit testing and refactoring Professional Test-Driven Development with C# shows you how to create great TDD processes right away.

Head First Android cuts through the fog of dozens of components, hundreds of API calls and focuses on the core skills you need. Do you want a book that is more than simply a reproduction of the online documentation? A book that is more like a course, taking you step-by-step through the development of real applications, just as if an experienced Android developer was sitting right next to you? This book teaches Android development by getting you to do Android development. In a succession of steadily more advanced chapters we take you from creating your first Android app, through to: Integrating apps with databases Designing interfaces rationally Connecting your app to the network Integrating with third-party apps.

Android Best Practices by Godfrey Nolan shows you how to make your Android apps stand out from the crowd with great reviews. Why settle for just making any Android app? Build a brilliant Android app instead that lets your users praise it for ease of use, better performance, and more. Using a series of example apps which gradually evolve throughout this book, Android Best Practices brings together current Android best practices from user interface (UI)/user experience (UX) design, test-driven development (TDD), and design patterns (e.g., MVC) to help you take your app to the next level. In this book you’ll learn how to: • Use Android design patterns for consistent UI experience on many devices • Use agile techniques such as test-driven development, behavior-driven development, and continuous integration • Improve the speed and overall performance of your app • Organize an Android app using design patterns such as MVC/MVP • Create and consume REST and SOAP web services Designing and developing an app that runs well on many if not all the leading Android smartphones and tablets today can be one of the most daunting challenges for Android developers. Well, this book takes much of the mystery out of that for you. After reading and using Android Best Practices, you'll become a much better Android app designer and developer, which in turn can make your apps better placed and more successful in the market place.

Build robust Scala applications by implementing the fundamentals of test-driven development in your workflow About This Book Get a deep understanding of various testing concepts such as test-driven development (TDD) and BDD Efficient usage of the built-in Scala features such as ScalaTest, specs2, and Scala check Change your approach towards problem solving by thinking about the boundaries of the problem and its definition rather than focusing on the solution Who This Book Is For This book is for Scala developers who are looking to write better quality and easily maintainable code. No previous knowledge of TDD/BDD is required. What You Will Learn Understand the basics of TDD and its significance Refactoring tests to build APIs in order to increase test coverage How to leverage the inbuilt Scala testing modules like ScalaTest, specs2 and Scala Check Writing test fixtures and apply the concepts of BDD How to divide tests to run at different points in continuous delivery cycle Benefits of refactoring and how it affects the final quality of code produced Understanding of SBT based build environment and how to use it to run tests The fundamentals of mocking and stubbing in Scala and how to use it efficiently In Detail Test-driven development (TDD) produces high-quality applications in less time than is possible with traditional methods. Due to the systematic nature of TDD, the application is tested in individual units as well as cumulatively, right from the design stage, to ensure optimum performance and reduced debugging costs. This step-by-step guide shows you how to use the principles of TDD and built-in Scala testing modules to write clean and fully tested Scala code and give your workflow the change it needs to let you create better applications than ever before.

Building on from that you will learn about the ScalaTest API and how to refactor code to produce high-quality applications. We'll teach you the concepts of BDD (Behavior-driven development) and you'll see how to add functional tests to the existing suite of tests. You'll be introduced to the concepts of Mocks and Stubs and will learn to increase test coverage using properties. With a concluding chapter on miscellaneous tools, this book will enable you to write better quality code that is easily maintainable and watch your apps change for the better. Style and approach This step-by-step guide explains the significance of TDD in Scala through various practical examples.
