Learning Object Oriented Programming Design And Tdd With Pharo

Pharo is a modern, dynamically-typed, reflective, and pure object-oriented programming language. It offers strong productivity via a fully live programming environment. It supports Xtreme TDD, a powerful development technique that puts live objects at the center of the coding experience. More information at http://www.pharo.org. Pharoers are used to say that programmers will never program the same once they coded seriously in Pharo. Learning Pharo is easy. Software developers learn Pharo in a couple of days. In addition, you can follow an excellent online free lecture available at: http://mooc.pharo.org. This book covers all the key aspects of Pharo: its syntax and its core libraries such as collections and streams. It also takes the user over simple tutorials that present all the aspects of code development with tests and git management with Pharo. In addition, it presents advanced topics such as reflective facilities and meta-level.

Learning Object-Oriented Programming is an easy-to-follow guide full of hands-on examples of solutions to common problems with object-oriented code in Python, JavaScript, and C#. It starts by helping you to recognize objects from real-life scenarios and demonstrates that working with them makes it simpler to write code that is easy to understand and reuse. You will learn to protect and hide data with the data encapsulation features of Python, JavaScript, and C#. You will explore how to maximize code reuse by writing code capable of working with objects of different types, and discover the advantage of duck typing in both Python and JavaScript, while you work with interfaces and generics in C#. With a fair understanding of interfaces, multiple inheritance, and composition, you will move on to refactor existing code and to organize your source for easy maintenance and extension. Learning Object-Oriented Programming will help you to make better, stronger, and reusable code.

Test-Driven Development (TDD) is now an established technique for delivering better software faster. TDD is based on a simple idea: Write tests for your code before you write the code itself. However, this "simple" idea takes skill and judgment to do well. Now there's a practical guide to TDD that takes you beyond the basic concepts. Drawing on a decade of experience building real-world systems, two TDD pioneers show how to let tests guide your development and “grow” software that is coherent, reliable, and maintainable. Steve Freeman and Nat Pryce describe the processes they use, the design principles they strive to achieve, and some of the tools that help them get the job done. Through an extended worked example, you’ll learn how TDD works at multiple levels, using tests to drive the features and the object-oriented structure of the code, and using Mock Objects to discover and then describe relationships between objects. Along the way, the book systematically addresses challenges that development teams encounter with TDD—from integrating TDD into your processes to testing your most difficult features. Coverage includes Implementing TDD effectively: getting started, and maintaining your momentum throughout the project Creating cleaner, more expressive, more sustainable code Using tests to stay relentlessly focused on sustaining quality Understanding how TDD, Mock Objects, and Object-Oriented Design come together in the context of a real software development project Using Mock Objects to guide object-oriented designs Succeeding where TDD is difficult: managing complex test data, and testing persistence and concurrency

Pharo is a modern, dynamically-typed, reflective, and pure object-oriented programming language - http://www.pharo.org. Pharo inherits and enhances the testing spirit from its ancestor Smalltalk. Indeed, Pharo's SUnit framework is the one of key asset of Agile Development as brought forward by K. Beck in its Test-Driven Development seminal book. But Pharo is much more powerful. It defines and supports eXtreme Test-Driven Development, a.k.a TDD on Steriods. Unique to Pharo, eXtreme Test-Driven Development is a powerful development technique that puts live objects at the center of the coding experience. With its unique flow, it delivers an excellent and unforeseen productivity mixing a fully live programming environment with TDD. In this book you will learn all the elements around TDD and XTDD. You will be empowered and understand why writing tests is not a side effect but a key element of the development process. Once immersed into XTDD you will not program the same way anymore.

Discover the untapped features of object-oriented programming and use it with other software tools to code fast, efficient applications. Key FeaturesExplore the complexities of object-oriented programming (OOP)Discover what OOP can do for youLearn to use the key tools and software engineering practices to support your own programming needsBook Description Your experience and knowledge always influence the approach you take and the tools you use to write your programs. With a sound understanding of how to approach your goal and what software paradigms to use, you can create high-performing applications quickly and efficiently. In this two-part book, you’ll discover the untapped features of object-oriented programming and use it with other software tools to code fast and efficient applications. The first part of the book begins with a discussion on how OOP is used today and moves on to analyze the ideas and problems that OOP doesn’t address. It continues by deconstructing the complexity of OOP, showing you its fundamentally simple core. You’ll see that, by using the distinctive elements of OOP, you can learn to build your applications more easily. The next part of this book talks about acquiring the skills to become a better programmer. You’ll get an overview of how various tools, such as version control and build management, help make your life easier. This book also discusses the pros and cons of other programming paradigms, such as aspect-oriented programming and functional programming, and helps to select the correct approach for your projects. It ends by talking about the philosophy behind designing software and what it means to be a "good" developer. By the end of this two-part book, you will have learned that OOP is not always complex, and you will know how you can evolve into a better programmer by learning about ethics, teamwork, and documentation. What you will learnUntangle the complexity of object-oriented programming by breaking it down to its essential building blocksRealize the full potential of OOP to design efficient, maintainable programsUtilize coding best practices, including TDD, pair programming and code reviews, to improve your workUse tools, such as source control and IDEs, to work more efficientlyLearn how to most productively work with other developersBuild your own software development philosophyWho this book is for This book is ideal for programmers who want to understand the philosophy behind creating software and what it means to be “good” at designing software. Programmers who want to deconstruct the OOP paradigm and see how it can be reconstructed in a clear, straightforward way will also find this book useful. To understand the ideas expressed in this book, you must be an experienced programmer who wants to evolve their practice.

In OBJECT THINKING, esteemed object technologist David West contends that the mindset makes the programmer—not the tools and techniques. Delving into the history, philosophy, and even politics of object-oriented programming, West reveals how the best programmers rely on analysis and conceptualization—on thinking—rather than formal process and methods. Both provocative and pragmatic, this book gives form to what’s primarily been an oral tradition among the field’s revolutionary thinkers—and it illustrates specific object-behavior practices that you can adopt for true object design and superior results. Gain an in-depth understanding of: Prerequisites and principles of object thinking. Object knowledge implicit in eXtreme Programming (XP) and Agile software development. Object conceptualization and modeling. Metaphors, vocabulary, and design for object development. Learn viable techniques for: Decomposing complex domains in terms of objects. Identifying object relationships, interactions, and constraints. Relating object behavior to internal structure and implementation design. Incorporating object thinking into XP and Agile practice.
