Test-Driven Development with Python, 2nd Edition Test-Driven Development with Python, 2nd Edition

By taking you through the development of a real web application from beginning to end, the second edition of this hands-on guide demonstrates the practical advantages of test-driven development (TDD) with Python. You'll learn how to write and run tests before building each part of your app, and then develop the minimum amount of code required to pass those tests. The result? Clean code that works. In the process, you'll learn the basics of Django, Selenium, Git, jQuery, and Mock, along with current web development techniques. If you're ready to take your Python skills to the next level, this book—updated for Python 3.6—clearly demonstrates how TDD encourages simple designs and inspires confidence. Dive into the TDD workflow, including the unit test/code cycle and refactoring; Use unit tests for classes and functions, and functional tests for user interactions within the browser; Learn when and how to use mock objects, and the pros and cons of isolated vs. integrated tests; Te ...

Each hands-on chapter offers progressively more challenging topics and techniques, broadening your skill set and enabling you to think in Node.js. Write asynchronous, non-blocking code using Node.js's style and patterns. Cluster and load balance services with Node.js core features and third-party tools. Harness the power of databases such as Elasticsearch and Redis. Work with many protocols, create RESTful web services, TCP socket clients and servers, and more. Test your code's functionality with Mocha, and manage its life cycle with npm. Discover how Node.js pairs a server-side event loop with a JavaScript runtime to produce screaming fast, non-blocking concurrency. Through a series of practical programming d ...
Modern JavaScript Applications Modern JavaScript Applications

Over the years, JavaScript has become vital to the development of a wide range of applications with different architectures. But JS moves lightning fast, and it's easy to fall behind. Modern JavaScript Applications is designed to get you exploring the latest features of JavaScript and how they can be applied to develop high-quality applications with different architectures. Begin by creating a single page application that builds on the innovative MVC approach using AngularJS, then move forward to develop an enterprise-level application with the microservices architecture using Node to build web services. After that, shift your focus to network programming concepts as you build a real-time web application with websockets. Learn to build responsive, declarative UIs with React and Bootstrap, and see how the performance of web applications can be enhanced using Functional Reactive Programming (FRP). Along the way, explore how the power of JavaScript can be in ...
Mastering JavaScript Mastering JavaScript

JavaScript is a high-level, dynamic, untyped, lightweight, and interpreted programming language. Along with HTML and CSS, it is one of the three essential technologies of World Wide Web content production, and is an open source and cross-platform technology. The majority of websites employ JavaScript and it is well supported by all modern web browsers without plugins. However, the JavaScript landscape has changed dramatically in recent years, and you need to adapt to the new world of JavaScript that people now expect. Mastering modern JavaScript techniques and the toolchain are essential to develop web-scale applications. Mastering JavaScript will be your companion as you master JavaScript and build innovative web applications. To begin with, you will get familiarized with the language constructs and how to make code easy to organize. You will gain a concrete understanding of variable scoping, loops, and best practices on using types ...
ArcGIS for JavaScript Developers by Example ArcGIS for JavaScript Developers by Example

The book starts by explaining the basics of the ArcGIS web mapping ecosystem. The book walks you through the development of six major applications, covering a wide variety of topics such as querying, rendering, advanced data visualization and performing map analytics. It also emphasizes on writing modular code using pure dojo, which is the preferred platform for developing web GIS applications using ArcGIS JavaScript API. By the end of the book, you will have gained enough practical experience to architect a robust and visually powerful mapping application using the API. ...
Learning JavaScript, 3rd Edition Learning JavaScript, 3rd Edition

This is an exciting time to learn JavaScript. Now that the latest JavaScript specification - ECMAScript 6.0 (ES6) - has been finalized, learning how to develop high-quality applications with this language is easier and more satisfying than ever. This practical book takes programmers (amateurs and pros alike) on a no-nonsense tour of ES6, along with some related tools and techniques. Author Ethan Brown (Web Development with Node and Express) not only guides you through simple and straightforward topics (variables, control flow, arrays), but also covers complex concepts such as functional and asynchronous programming. You'll learn how to create powerful and responsive web applications on the client, or with Node.js on the server. ...

Learning Behavior-driven Development with JavaScript Learning Behavior-driven Development with JavaScript

JavaScript is not only widely used to create attractive user interfaces for the Web, but with the advent of Node.js, it is also becoming a very popular and powerful language to write server-side applications. Using behavior-driven development and some common testing patterns and best practices, you will be able to avoid these traps. This book will show you how to do BDD in a practical way. We will start with a basic introduction of what BDD is and why the classical approach to testing has failed. Afterwards, we will dive directly into an introduction to Node.js, Mocha, and Sinon.JS. Finally, we will cover more advanced subjects such as how to write a fast and effective test suite for a RESTful web API, and how to do the same with a rich UI using Cucumber.js and Protractor. This book will give you great insight into how to architect your system to make it more testable and modular, but at the same time avoid the nightmare of abusing mock objects. ...
Reliable JavaScript Reliable JavaScript

Reliable JavaScript demonstrates how to create test-driven development for large-scale JavaScript applications that will stand the test of time and stay accurate through long-term use and maintenance. Taking a test-first approach to software architecture, this book walks you through several patterns and practices and explains what they are supposed to do by having you write unit tests. Write the code to pass the unit tests, so you not only develop your technique for structuring large-scale applications, but you also learn how to test your work. You'll come away with hands-on practice that results in code that is correct from the start, and has the test coverage to ensure that it stays correct during subsequent maintenance. All code is provided both in the text and on the web, so you can immediately get started designing more complete, robust applications. JavaScript has graduated from field-validation scripts to full-scale applications, but many developers still ...
