Concept Based Testing

Explore concept-based testing in C++ through this 58-minute ACCU Conference talk. Learn how to create generic tests for C++ concepts using C++17 features, focusing on the detection idiom and constexpr if. Discover techniques for verifying concept operations, handling partial concept implementations, and guiding class development. Gain insights into constraining classes and functions, testing incomplete models, and examining compound concepts like EqualityComparable and BidirectionalIterator. Suitable for C++ developers familiar with the language, but extensive template meta-programming knowledge is not required.
