Applying Object Design with Programming: Thinking in Objects, Agile Modeling, and TDD
Revision as of 11:30, 30 October 2011 by Clarman
Developing in Java, C#, C++, Python, or Ruby is not really about a new object-oriented (OO) programming language; it is about thinking in objects -- a different way to design software. This high-impact and hands-on course on skillful OO software analysis, design, and development is aimed at developers looking for solid OO programming skills and the ability to "think in objects".
Who is the author of this course, and their experience? This hands-on course is based on OO-industry leader Craig Larman’s extensive experience coaching and applying OO development for decades; Craig is the author of the world's most popular text on OO analysis and design, an industry and university standard text translated to 17 languages, used worldwide.
What are the key, core principles of object design or thinking in objects? How to apply them? In this course, developers learn these principles and apply them repeatedly, during agile modeling and during OO programming.
Is programming good and modeling bad? Or vice versa? This course goes beyond unsophisticated false dichotomies and shows developers how to apply both agile modeling and OO programming, combined with test-driven development (TDD) into a useful, efficient set of techniques.
How else to encourage thinking in objects? Humans are visual creatures. Using large whiteboard areas for agile modeling, to enhance OO thinking skills, is a powerful and fast educational tool to strengthen an object perspective.
How to support team-based development in which people learn from each other and align on a common design, versus individual isolated development? Although the main purpose of large-whiteboard agile modeling in this course is as a learning tool to enhance thinking in objects, also, via hands-on agile modeling in small teams people learn to design together and learn together as a team.
How can TDD be combined with agile modeling, to build quality in? TDD is a powerful technique to design and develop so that we build quality in by writing an automated test first (before the code), rather than last. This approach drives development to create highly-cohesive, low-coupled objects that support testability and dependency injection. Building quality in starts with hands-on mastery of solid object design principles, and is enhanced with team-based agile modeling, and with TDD. In this course, people learn to combine agile modeling and TDD in a way that they find useful, fast, and fun.
What language? The hands-on programming work can be in Java, C#, C++, Python, or Ruby. Ideally, all the students in one delivery of the course use the same language, because the learning, speed, tools, and issues related to each language are unique.
The course involves multiple iterations of a case study, in which the teams go through repeating cycles of agile modeling and OO development combined with TDD. On each cycle, the coach gradually introduces more principles and techniques to build software with agility.
We apply a variety of education techniques established over 20 years of coaching and mentoring to maximize the learning, value, and fun, including buzz groups, multi-modal learning, pair work, and lots of hands-on practice.
Methods of Education
Discussion, presentation, Q&A, workshop exercises
Developers. Because agile model is especially good for a whole team together, it is desirable if the majority of a team tasks this course together, to learn and apply a new common behavior.
Familiarity with a programming language
Upon completion of this course, students should be able to:
- think in objects and design object systems with the GRASP principles
- create well-crafted clean code in Java, C#, C++, etc, that expresses good object design and OO programming
- learn to think in objects via visualization with agile modeling
- design better object-oriented systems with 2 or 3 "gang of four" design patterns
- identify goals with user stories and/or use case names
- learn with system-sequence diagrams
- learn with a domain model
- apply acceptance TDD
- create and collaborate on designs to "think in objects" with activity diagrams, communication diagrams, and design class diagrams
- evolve models into code, via TDD
- create code with unit TDD
- know the use and misuse of mock objects
- design the connection between a UI and domain-logic layer to maintain a separation of concerns
- refactor code to remove "code smells" and create really clean code
- learn and collaborate with simple UML
