Future of Testing With C++20
summary
Claims a macro-free testing framework implemented in about 200 lines of C++20 that compiles and runs the example "\"hello world\"_test = [] { expect(12_i == fib(7)); }", then evolves into ut (about 2,000 LOC) as a single-header/module library using concepts, UDLs, immediate-invoke lambdas and source_location. Builds pass, colored failure messages include file and line, supports BDD, parameterized tests and a parallel runner in a few lines. Benchmarks show faster compile times and smaller binaries versus some older frameworks in the presented cases.
