Legacy code topics and modules

Just to clarify upfront: Any topic can be explored in depth at your request. Your needs come first. You decide what your team needs. We create the concept. If your team just wants an overview, then you can select a wide range of topics. However, it will likely be challenging for the team to implement what they have learned in practice afterwards.

So, if you want to work seriously and professionally with legacy code, it's better, based on our experience, to select fewer topics which we then discuss in depth during the training and conduct a sufficient number of practical workshops. Here, indeed, "less is more". In a consultation, we can best jointly identify which topics will be most beneficial for your team and your projects.

We don't preach theory, we solve problems! Get the maximum knowledge for your team. Compile the topics according to your previous knowledge and needs, depending on the project. Because individual learning brings the desired success!

Working with Legacy Code Techniken

What might a course with a focus on working with legacy code look like?

A course with this focus typically covers a selection of the following topics:

  • Golden Master
  • Seams
  • Test Coverage
  • Mutation Testing
  • Adding Features
  • Including a class in a test harness
  • Running a method in a test harness
  • Breaking monster classes
  • Modifying monster methods
  • Dependency breaking techniques

Introduction to Unit Test

Depending on the language, an introduction to the corresponding unit test and mocking framework is introduced. For example, JUnit 5 for Java, Pytst for Python, NUnit for C#, Catch2 for C++, and Jasmine/Jest and Mocha for JavaScript.

  • Unit Test Basics
  • Test Driven Development (TDD)
  • Mocking Framework

Clean Code Basics

The most important clean code concepts are covered in a language-independent manner, as well as best practices in the respective programming language are deepened with many examples and tasks.

  • Tools for improving code quality
  • Clean Code: Names, comments, functions
  • SOLID principles and testable design

Refactoring Patterns Basics

The most important refactoring patterns are explained in a practical way using several examples and workshops.

  • Making Method Calls Simpler (15 Patterns)
  • Simplifying Conditional Expressions (8 Patterns)
  • Moving Feature between Objects (8 Patterns)
  • Organising Data (16 Patterns)
  • Composing Methods (9 Patterns)
  • Dealing with Generalisation (12 Patterns)
  • Big Refactoring (4 Patterns)

Working effectively as a team

These modules cover techniques that help make teamwork more productive and improve the quality of the resulting software.

The Working effectively as a team module includes the following focus areas:

  • Version control (Git)
  • Docker
  • Continuous Integration (CI)
  • Workflows: Issue Tracking, Pull/Merge Requests
  • Example: working with a local GitLab instance in Docker
  • Kubernetes
  • Elasticsearch/Kibana (OpenSearch/Dashboards)

Do graduates of the Legacy Code courses receive a certificate?

Of course, as a participant in a Legacy Code course, you will receive a certificate. The prerequisite for this is full participation in all course units and programming tasks, and the successful programming of a small final project. However, after an intensive Legacy Code course, this will certainly bring you more joy than stress.
