Doctest is a new C++ testing framework but it is by far the fastest both in compile times (by orders of magnitude) and runtime compared to other feature-rich alternatives. It brings the ability of compiled languages such as D, Rust, and Nim to have tests written directly in the production code by providing a fast, transparent, and flexible test runner with a clean interface.

RCRL is a tiny engine for interactive C++ compilation and execution (implemented in just a few source files) and works on any platform with any toolchain—the main focus is easy integration. It is an elegant alternative to Cling.

This talk introduces the Doctest framework along with my best open-source work and goes on to describe useful and generally applicable C++ techniques from its implementation, like how to:
• Register code automatically before the program enters main()
• Decompose expressions with templates
• Translate exceptions: type-erased user-registerable translators
• Write a header-only library which compiles very very fast not at the cost of runtime performance
• Implement assert macros that don't result in code bloat
• Deal with warnings outside of the framework header—generated by code expanded from macros
