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.

    Banister Fletcher has been the standard one volume architectural history for over 100 years and continues to give a concise and factual account of world architecture from the earliest times.In this twentieth and centenary edition, edited by Dan Cruickshank with three consultant editors and fourteen new contributors, chapters have been recast and expanded and a third of the text is new. * There are new chapters on the twentieth-century architecture of the Middle East (including Israel), South-east Asia, Hong Kong, Japan and Korea, the Indian subcontinent, Russia and the Soviet Union, Eastern Europe and Latin America. * The chapter on traditional architecture of India has been rewritten and the section on traditional Chinese architecture has been expanded, both with new specially commissioned drawings* The architecture of the Americas before 1900 has been enlarged to include, for the first time, detailed coverage of Latin America and the Caribbean* The book's scope has been widened to include more architecture from outside Europe* The bibliography has been expanded into a separate section and is a key source of information on every period of world architecture* The coverage of the 20th century architecture of North America has been divided into two chapters to allow fuller coverage of contemporary works* 20th century architecture of Western Europe has been radically recast* For the first time the architecture of the twentieth century is considered as a whole and assessed in an historical perspective* Coverage has been extended to include buildings completed during the last ten years* The coverage of Islamic architecture has been increased and re-organised to form a self contained sectionThis unique reference book places buildings in their social, cultural and historical settings to describe the main patterns of architectural development, from Prehistoric to the International Style. Again in the words of Sir Banister Fletcher, this book shows that 'Architecture ... provides a key to the habits, thoughts and aspirations of the people, and without a knowledge of this art the history of any period lacks that human interest with which it should be invested.'

    This book is an introduction to the concepts of computer programming within the context of the visual arts. It offers a comprehensive reference and text for Processing (www.processing.org), an open-source programming language that can be used by students, artists, designers, architects, researchers, and anyone who wants to program images, animation, and interactivity. The ideas in Processing have been tested in classrooms, workshops, and arts institutions, including UCLA, Carnegie Mellon, New York University, and Harvard University. Tutorial units make up the bulk of the book and introduce the syntax and concepts of software (including variables, functions, and object-oriented programming), cover such topics as photography and drawing in relation to software, and feature many short, prototypical example programs with related images and explanations. More advanced professional projects from such domains as animation, performance, and typography are discussed in interviews with their creators. "Extensions" present concise introductions to further areas of investigation, including computer vision, sound, and electronics.
