Crafting & Design code with Sandro Mancuso

Intensive, 3-days, hands-on crafts & design coding workshop with Sandro Mancuso

This course is designed to help developers write well-crafted code. Meaning code that is clean, testable, maintainable, and an expression of the business domain. The course is entirely hands-on, designed to teach developers practical techniques they can immediately apply to real-world projects.

The third and final day is dedicated to software design at the application level (internal structure, layers, components, delivery mechanism, core domain) and also at the microservices level, using business requirements to drive their design (define the responsibility of each service, how services collaborate, their internal and external visibility, number of services we need to create, etc.) Developers will work in groups of 4 and develop design solutions that are later shared with the wider group. Many design discussions during exercises focused on real-world scenarios.

Why attend?

Software Craftsmanship is at the heart of this course. You will learn about the Software Craftsmanship attitude to development and how to apply it to your workplace. Writing Clean Code is difficult. Cleaning existing code, even more so. You should attend if you want to:

  • Write clean code that is easy to understand and maintain
  • Become more proficient in Test-Driven Development (TDD): using tests to design and build your code base
  • Focus your tests and production code according to business requirements using Outside-In TDD (a.k.a. the London School of TDD)

Clean code necessitates good design. In the process of driving your code through tests, you will learn how to:

  • Understand design principles that lead to clean code
  • Avoid over-engineering and large rewrites by incrementally evolving your design using tests

Once you understand the principles at work, we will apply them to Legacy Code to help you gain confidence in improving legacy projects through testing, refactoring, and redesigning.


  • TDD lifecycle and the Outside-In style of TDD
  • Writing unit tests that express intent, not implementation
  • Using unit tests as a tool to drive good design
  • Expressive code
  • Testing and Refactoring Legacy Code
  • Introduction to SOLID Principles and Domain-Driven Design
  • Principles of Domain Driven Design.
  • IDD – Interaction Driven Design.
  • Structure projects to express what the application does and what it is about.
  • Differences between layers, hexagons, features, and components.
  • Modeling behavior using Outside-In Design.
  • Identifying services from business rules.
  • Express design and architecture in code, but keep your domain clear
  • Understanding Impact Mapping and how a services architecture can be derived from it.

The course is fully hands-on, and developers will write a lot of code.


Software developers that:

  • Are familiar with at least one Object-Oriented language
  • Can understand Java or C#
  • Can write and execute unit tests using a framework (such as JUnit, NUnit, etc.)
  • Have a basic understanding of mock objects

Prerequisites Developers must:

  • Bring their laptops
  • Have a development environment consisting of:
    • Their favorite Object-Oriented language
    • A unit test framework
    • A mocking library
  • Be able to create projects, build source code, and run test cases in their development environment.
  • In addition, a distributed version control system such as Git is desirable.
