Keynote: C++ Contracts, Testing and the Pursuit of Well Defined Behaviour - Timur Doumler - CppNorth 2023

Everyone wants their code to be fast, safe, and correct. It seems that we cannot achieve all three simultaneously – or can we? What if Design by Contract goes a long way towards achieving this goal?

This talk covers what Contracts are, why they bring huge benefits to our codebases and tooling, and how to use them in C++ today. We will further look at the ongoing effort to standardise a contract-checking facility for C++26, which would enable Contracts use across libraries and codebases. We will learn about the difference between assertions and assumptions, hard and soft undefined behaviour, narrow and wide contracts, and testing your tests — and reconsider how we design, test, and implement our C++ APIs and how we think about code.
