Even bad code can function. But if code isn't clean, it can bring a development organisation to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn't have to be that way!
In this three-day Clean Code Workshop you will learn the principles and practices of Clean Code as described in Robert C. Martin's book: Clean Code: A Handbook of Agile Software Craftsmanship. You will also receive this book as part of the course materials.
This Clean Code workshop alternates between lectures and exercises so that you can experience, first-hand, the practices and disciplines of the following fundamental topics:
- Professionalism, Craftsmanship, and Clean Code.
- Choosing Meaningful Names
- Writing Clean Functions
- The Proper Use of Comments
- Coding Style and Formatting
- Object Oriented Programming vs. Procedural Programming.
- Error Handling Boundaries between Subsystems
- Unit testing, and Test Driven Development
- Writing Clean Classes Systems
- Plan vs. Emergence
- Smells and Heuristics.
Learn how to:
- Develop an attitude of professional craftsmanship
- Write great code and transform weak, old code
Create good names, functions, objects & classes
Format code for maximum readability
Implement complete error handling without obscuring code logic
Apply effective unit testing and refactoring techniques.
