Test Infrastructure: preferably not Google Test!

I think @dsankel wrote a paper about lit for beman, see this thread:

Considering Lit for the Beman Project

Abstract The LLVM Integrated Tester (lit) is being proposed as the recommended test framework for Beman Projects. While it supports compilation failure testing, it has limited usage experience, introduces complexity, and has ergonomics challenges. We instead suggest recommending a more popular framework, such as GTest, supplemented with CMake functions adding negative compilation testing capabilities. Link to full doc…

David’s conclusion was:

Conclusion

We’ve investigated making lit the recommended Beman testing framework. Unlike other frameworks it has support for compilation failure tests, but it has several drawbacks including lack of popularity, complexity, and ergonomics challenges. Our recommendation is to instead adopt a more popular framework, such as GTest, and supplement it with CMake functions that add compilation failure capabilities.
