Working with a test framework

All participants will receive a certificate of attendance and an Open Badge, which we will distribute via mybadges.io create.

The seminar is aimed at software developers who are just beginning to deal with the topic of software quality.
  • The problem: increasing costs
  • The Clean Code Developer Initiative
  • Clean code principles and practices
  • Dependencies
  • Integration Operation Segregation Principle (IOSP)
  • Test strategies
  • Don't Repeat Yourself (DRY)
  • Single Responsibility Principle (SRP)

Learning objectives

In this seminar, participants will learn the basics of Clean Code. Among other things, they learn about the three most important Clean Code Developer principles:

These principles are deepened through exercises, other principles such as the SOLID Principles are addressed.

In addition to the principles of software development, this seminar is about writing automated tests. The focus here is on the strategy of testing.


Participants must be able to use a programming language fluently. Participants must also be able to use a test framework such as NUnit, JUnit or similar. Further details you can find here. If you have no previous knowledge of using a test framework, we offer a Introductory seminar to.
