Properties of Unit Tests

What are the desired properties of unit tests to make them most useful? This talk goes through the most common use cases for unit tests and deducts those desired properties from them. Slides

The talk was held:

• At the NDC TechTown conference on August 31st 2022 in Kongsberg, Norway.
• At the MeetingC++ conference on November 19th 2022 in Berlin, Germany.

Identifying Common Code Smells

I talk about what code smells are and show eight of the most common language agnostic and C++ specific code smells, as well as how to fix them. Each smell is shown using examples from open source code bases. Slides

The talk was held on several occasions:

• At the MeetingC++ conference on November 15th 2019 in Berlin, Germany (different title, video)
• At the C++ On Sea conference on July 6th 2022 in Folkestone, UK (video)
• At the NDC TechTown conference on September 1st 2022 in Kongsberg, Norway.

Bringing Clean Code to Large Scale Legacy C++ Applications

A talk about the experiences I gathered in several large and old enterprise C++ code bases. (Slides)

The talk was held on several occasions:

• At the Advanced Developers C++ Conference April 26th 2016 in Erding, Germany
• At the Clean Code Days June 3rd 2016 in Munich, Germany
• At the C++ User Group July 11th 2016 in Hannover, Germany
