The pytest testing framework helps you write tests quickly and keep them readable and maintainable - with no boilerplate code. Using a robust yet simple fixture model, it's just as easy to write small tests with pytest as it is to scale up to complex functional testing for applications, packages, and libraries. This book shows you how.For Python-based projects, pytest is the undeniable choice to test your code if you're looking for a full-featured, API-independent, flexible, and extensible testing framework. With a full-bodied fixture model that is unmatched in any other tool, the pytest framework gives you powerful features such as assert rewriting and plug-in capability - with no boilerplate code.With simple step-by-step instructions and sample code, this book gets you up to speed quickly on this easy-to-learn and robust tool. Write short, maintainable tests that elegantly express what you're testing. Add powerful testing features and still speed up test times by distributing tests across multiple processors and running tests in parallel. Use the built-in assert statements to reduce false test failures by separating setup and test failures. Test error conditions and corner cases with expected exception testing, and use one test to run many test cases with parameterized testing. Extend pytest with plugins, connect it to continuous integration systems, and use it in tandem with tox, mock, coverage, unittest, and doctest.Write simple, maintainable tests that elegantly express what you're testing and why.What You Need: The examples in this book are written using Python 3.6 and pytest 3.0. However, pytest 3.0 supports Python 2.6, 2.7, and Python 3.3-3.6.

    In this one-of-a-kind text, author V. Anton Spraul breaks down the ways that programmers solve problems and teaches you what other introductory books often ignore: how to Think Like a Programmer. Each chapter tackles a single programming concept, like classes, pointers, and recursion, and open-ended exercises throughout challenge you to apply your knowledge. You'll also learn how to:Split problems into discrete components to make them easier to solve Make the most of code reuse with functions, classes, and libraries Pick the perfect data structure for a particular job Master more advanced programming tools like recursion and dynamic memory Organize your thoughts and develop strategies to tackle particular types of problems Although the book's examples are written in C++, the creative problem-solving concepts they illustrate go beyond any particular language; in fact, they often reach outside the realm of computer science. As the most skillful programmers know, writing great code is a creative art—and the first step in creating your masterpiece is learning to Think Like a Programmer.

    They get frustrated losing their scroll position; they get annoyed waiting for refresh; they struggle to reorient themselves on every new page. And the list goes on. With asynchronous JavaScript and XML, known as "Ajax," you can give them a better experience. Once users have experienced an Ajax interface, they hate to go back. Ajax is new way of thinking that can result in a flowing and intuitive interaction with the user.Ajax in Action helps you implement that thinking--it explains how to distribute the application between the client and the server (hint: use a "nested MVC" design) while retaining the integrity of the system. You will learn how to ensure your app is flexible and maintainable, and how good, structured design can help avoid problems like browser incompatibilities. Along the way it helps you unlearn many old coding habits. Above all, it opens your mind to the many advantages gained by placing much of the processing in the browser. If you are a web developer who has prior experience with web technologies, this book is for you. 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.

    Why is this open-source tool so popular? Because it automates a tedious task: persisting your Java objects to a relational database. The inevitable mismatch between your object-oriented code and the relational database requires you to write code that maps one to the other. This code is often complex, tedious and costly to develop. Hibernate does the mapping for you.Not only that, Hibernate makes it easy. Positioned as a layer between your application and your database, Hibernate takes care of loading and saving of objects. Hibernate applications are cheaper, more portable, and more resilient to change. And they perform better than anything you are likely to develop yourself."Hibernate in Action" carefully explains the concepts you need, then gets you going. It builds on a single example to show you how to use Hibernate in practice, how to deal with concurrency and transactions, how to efficiently retrieve objects and use caching.The authors created Hibernate and they field questions from the Hibernate community every day-they know how to make Hibernate sing. Knowledge and insight seep out of every pore of this book."What's Inside"- ORM concepts- Getting started- Many real-world tasks- The Hibernate application development process

    And in a perfect world, those who produce the best code are the most successful. But in our perfectly messy world, success also depends on how you work with people to get your job done.In this highly entertaining book, Brian Fitzpatrick and Ben Collins-Sussman cover basic patterns and anti-patterns for working with other people, teams, and users while trying to develop software. It's valuable information from two respected software engineers whose popular video series, "Working with Poisonous People," has attracted hundreds of thousands of viewers.You'll learn how to deal with imperfect people--those irrational and unpredictable beings--in the course of your work. And you'll discover why playing well with others is at least as important as having great technical skills. By internalizing the techniques in this book, you'll get more software written, be more influential, be happier in your career.

    <br> <br><h2>DISCOVER: Launching and Pricing Strategies That Work in 2013</h2><br>Kindle publishing offers a rare opportunity to make money with your words. Simply write a good book and you'll tap into the world's largest online store. But it's not the utopian business model that some Internet gurus claim. You have to work hard and you have to constantly adapt your marketing strategies if you want to be successful. <br><br>One tactic in particular that doesn't work like it once did is the "free day promotion" that Amazon provides through the KDP Select program. In the past, you could give away a book and see an immediate bump in sales. Moreover, many authors were able to launch their book for free and see it climb the charts once it switched to paid. Unfortunately, recent changes to Amazon's algorithm has led to diminished success with this strategy. Some people are even saying, "KDP Select is dead."<br><br>The question is, if KDP Select no longer works, what can an author do to launch or increase sales? <br><br>A possible solution is the "$.99 pricing" strategy." Rather than giving away a book, some people market it at a discounted rate (usually $.99), which ultimately leads to lots of sales at a higher price. <br><br>These two choices leave many authors confused. Do the free days still work? Or should an author use the $.99 pricing strategy? In other words, is $.99 the new free? <br><br>With the booklet, "<b>Is $.99 the New Free</b>" you'll get a detailed case study of the launching and pricing techniques that <i>actually</i> drive sales on Amazon.com. <br><br><h2>INSIDE:: Is $.99 the New Free? - The Truth About Launching and Pricing Your Kindle Books</h2><br><br>Inside "<b>Is $.99 the New Free</b>" you'll get short and actionable content that answers the following questions:<br><ul><li><b>Why is it important to track your Kindle book sales?</b></li><br><li>What authors benefit best from offering free books through KDP Select?</li><br><li><b>Is it better to launch a book for free or sell it at $.99?</b></li><br><li>How does "visibility" work on Amazon?</li><br><li><b>How can you make a book permanently free on Amazon?</b></li><br><li>When should you move a book to other platforms?</li><br><li><b>How can you build an author platform?</b></li></ul><br>Kindle publishing is constantly evolving.
