Ruby Developer's Guide

Ruby Developer Guide

David Flanagan, Yukihiro Matsumoto The Ruby Programming Language is the authoritative guide to Ruby and provides comprehensive coverage of versions 1.8 and 1.9 of the language. It was written (and illustrated!) by an all-star team: David Flanagan, bestselling author of programming language "bibles" (including [removed] The Definitive Guide and Java in a Nutshell) and committer to the Ruby Subversion repository. Yukihiro "Matz" Matsumoto, creator, designer and lead developer of Ruby and author of Ruby in a Nutshell, which has been expanded and revised to become this book. why the lucky stiff, artist and Ruby programmer extraordinaire. This book begins with a quick-start tutorial to the language, and then explains the language in detail from the bottom up: from lexical and syntactic structure to datatypes to expressions and statements and on through methods, blocks, lambdas, closures, classes and modules. The book also includes a long and thorough introduction to the rich API of the Ruby platform, demonstrating -- with heavily-commented example code -- Ruby's facilities for text processing, numeric manipulation, collections, input/output, networking, and concurrency. An entire chapter is devoted to Ruby's metaprogramming capabilities. The Ruby Programming Language documents the Ruby language definitively but without the formality of a language specification. It is written for experienced programmers who are new to Ruby, and for current Ruby programmers who want to challenge their understanding and increase their mastery of the language.

技能：一个软件开发人员的生活和职业指南一共三个部分 1.编程技能 2.自由职业技能 3.职业技能 About the Author Jordan Hudgens is the CTO and founder of DevCamp, where he leads instruction and curriculum development for all the DevCamp and Bottega code schools around the US. As a developer over the past decade, Jordan has traveled the world building applications and training individuals on a wide variety of topics, including Ruby development, big data analysis, and software engineering. Jordan focuses on project-driven education as opposed to theory-based development. This style of teaching is conducive to learning how to build real-world products that adhere to industry best practices. Additionally, Jordan has published multiple books on programming and computer science along with developing training curriculum for Learn.co, DevCamp, and AppDev on the topics, namely Ruby on Rails, Java, AngularJS, NoSQL, API development, and algorithms.

How do successful agile teams deliver bug-free, maintainable software—iteration after iteration? The answer is: By seamlessly combining development and testing. On such teams, the developers write testable code that enables them to verify it using various types of automated tests. This approach keeps regressions at bay and prevents “testing crunches”—which otherwise may occur near the end of an iteration—from ever happening. Writing testable code, however, is often difficult, because it requires knowledge and skills that cut across multiple disciplines. In Developer Testing, leading test expert and mentor Alexander Tarlinder presents concise, focused guidance for making new and legacy code far more testable. Tarlinder helps you answer questions like: When have I tested this enough? How many tests do I need to write? What should my tests verify? You’ll learn how to design for testability and utilize techniques like refactoring, dependency breaking, unit testing, data-driven testing, and test-driven development to achieve the highest possible confidence in your software. Through practical examples in Java, C#, Groovy, and Ruby, you’ll discover what works—and what doesn’t. You can quickly begin using Tarlinder’s technology-agnostic insights with most languages and toolsets while not getting buried in specialist details. The author helps you adapt your current programming style for testability, make a testing mindset “second nature,” improve your code, and enrich your day-to-day experience as a software professional. With this guide, you will Understand the discipline and vocabulary of testing from the developer’s standpoint Base developer tests on well-established testing techniques and best practices Recognize code constructs that impact testability Effectively name, organize, and execute unit tests Master the essentials of classic and “mockist-style” TDD Leverage test doubles with or without mocking frameworks Capture the benefits of programming by contract, even without runtime support for contracts Take control of dependencies between classes, components, layers, and tiers Handle combinatorial explosions of test cases, or scenarios requiring many similar tests Manage code duplication when it can’t be eliminated Actively maintain and improve your test suites Perform more advanced tests at the integration, system, and end-to-end levels Develop an understanding for how the organizational context influences quality assurance Establish well-balanced and effective testing strategies suitable for agile teams Table of Contents Chapter 1 Developer Testing Chapter 2 Testing Objectives, Styles, and Roles Chapter 3 The Testing Vocabulary Chapter 4 Testability from a Developer’s Perspective Chapter 5 Programming by Contract Chapter 6 Drivers of Testability Chapter 7 Unit Testing Chapter 8 Specification-based Testing Techniques Chapter 9 Dependencies Chapter 10 Data-driven and Combinatorial Testing Chapter 11 Almost Unit Tests Chapter 12 Test Doubles Chapter 13 Mocking Frameworks Chapter 14 Test-driven Development—Classic Style Chapter 15 Test-driven Development—Mockist Style Chapter 16 Duplication Chapter 17 Working with Test Code Chapter 18 Beyond Unit Testing Chapter 19 Test Ideas and Heuristics Appendix A: Tools and Libraries Appendix B: Source Code
