React Native for iOS DevelopmentThis book is your hands-on guide to developing native iOS apps with ease. With React Native for iOS Development you'll challenge the status quo of native iOS development with revolutionary components, asynchronous execution, unique methods for touch handling, and much more.
You will begin by understanding the path breaking concepts of React.js, which makes it distinctive. You will set up React Native and begin exploring the anatomy of React Native apps. You'll also learn about flux architecture, how it differs from MVC, and how you can include it in your React Native project to solve problems differently and efficiently. Next, you will learn to create stunning user interfaces and interact with various device capabilities. You will then boost your development by including some popular packages already developed by the React Native community that will helps you write less but do more. Finally, you'll learn to how write test cases and submit your application to App Store.

Relational Database ProgrammingLearn the best way of writing code to run inside a relational database. This book shows how a holistic and set-oriented approach to database programming can far exceed the performance of the row-by-row model that is too often used by developers who haven't been shown a better way.
Two styles of programming are encountered in the database world. Classical programming as taught in many universities leads to an atomic, row-oriented, and procedural style inspired by the structured models of programming. In short, many application developers write in the relational database exactly like in the user interface. The other style of programming is holistic, data set oriented, and coded mainly in SQL. This is the style of the database developer.
The set based and holistic style of development is not promoted enough in universities, and many application developers are not fully aware of it. There are many performance issues all over the world in relational databases due to the use of the ato ...
RESTful Web ClientsWeb-based REST and Hypermedia services are becoming more common every day, but very few client libraries take advantage of these powerful API features—mostly because the techniques and patterns needed to create successful hypermedia clients have been ignored. Yet, when done right, hypermedia-based client applications exhibit more stability and flexibility than typical one-off custom client code.
This practical book takes you on a journey from custom bespoke implementations to powerful general-purpose client applications and, along the way, shows how you can harness many of the basic principles that underpin the Web. Throughout the book, you'll find practical, approachable examples and dialogs, as well as clear guidance on how to understand this increasingly important conversation. ...
Rolling Out 5GThis book describes insufficiencies and challenges of 4G in the light of impending and crucial future communication needs, details lessons learned from an implementation and system operation background, and illustrates the way towards the next generation – 5G. Key changes and additions to 5G in terms of use cases, applications for and explorations of the technology are discussed.
Among all of the technological disruptions, the book features detailed coverage of two stand out in particular – mmWave and spectrum sharing technologies including the evolution of LTE Advanced Pro.
The authors are highly experienced experts with valuable know-how in the field of wireless communications related research projects defining future technological trends. This unique group of talents will be able to consider the 5G technology evolution from all angles mentioned: long-term research, standardization and regulation, product design and marketization. This approach allows this much-needed book ...
RSpec EssentialsThis 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 rea ...

tmux 2You have a database console, web server, test runner, and text editor running at the same time, but switching between them and trying to find what you need takes up valuable time and breaks your concentration. By using tmux 2.3, you can improve your productivity and regain your focus. This book will show you how.
This second edition includes many features requested by readers, including how to integrate plugins into your workflow, how to integrate tmux with Vim for seamless navigation - oh, and how to use tmux on Windows 10.
Use tmux to manage multiple terminal sessions in a single window using only your keyboard. Manage and run programs side by side in panes, and create the perfect development environment with custom scripts so that when you're ready to work, your programs are waiting for you. Manipulate text with tmux's copy and paste buffers, so you can move text around freely between applications. Discover how easy it is to use tmux to collaborate remotely with others, and ex ...
The Way of the Web TesterIf you're a traditional software tester who has never written an automated test before, this is the perfect book for getting started. Together, we'll go through everything you'll need to start writing your own tests.
If you're a developer, but haven't thought much about testing, this book will show you how to move fast without breaking stuff. You'll test RESTful web services and legacy systems, and see how to organize your tests.
And if you're a team lead, this is the Rosetta Stone you've been looking for. This book will help you bridge that testing gap between your developers and your testers by giving your team a model to discuss web testing, and most importantly, to coordinate their efforts.
The Way of the Web Tester is packed with cartoons, graphics, best practices, war stories, plenty of humor, and hands-on tutorial exercises that will get you doing the right things, the right way. ...
Test-Driving JavaScript ApplicationsDesign and code JavaScript applications with automated tests. Writing meaningful tests is a skill that takes learning, some unlearning, and a lot of practice, and with this book, you'll hone that skill. Fire up the editor and get hands-on through practical exercises for effective automated testing and designing maintainable, modular code.
Start by learning when and why to do manual testing vs. automated verification. Focus tests on the important things, like the pre-conditions, the invariants, complex logic, and gnarly edge cases. Then begin to design asynchronous functions using automated tests. Carefully decouple and mock out intricate dependencies such as the DOM, geolocation API, file and database access, and Ajax calls to remote servers.
Step by step, test code that uses Node.js, Express, MongoDB, jQuery, and AngularJS. Know when and how to use tools such as Chai, Istanbul, Karma, Mocha, Protractor, and Sinon. Create tests with minimum effort and run them fast without having ...
