This looks hella good, I particularly am intrigued by the nested setup/teardown system. The natural assert syntax is interesting, too, amazing what macros can accomplish. Appropriately, the first question that came to mind was, "what's the catch?" :)

Yup. I found it interesting after a co-worker pointed it out to me because it looks and works kind of like RSpec. We are currently considering using it for a new project and it seems mature enough to give it a go. I'm currently toying with writing a JSONReporter so we can use that as an additional test result output format and I agree, so far it seems to be a really well done project.

FWIW I've been using Catch for a few years now, and I find it mature enough for real world usage.

The macro trick is at https://github.com/philsquared/Catch/blob/785db43bb2cd64bfe7...: planting the tested expression to the right of an operator ->*, which is overloadable and allows for changing the type of the left hand side in the comparison. The rest is a "simple matter of programming". Clever but probably a bit cute - errors would look weird if the expression isn't set up as expected.

This looks really good. Do you plan to include BeforeEach and AfterEach? I'll try this out and maybe move my projects to this.

I started working on something similar[1] a few days ago just as a proof of concept.

Also uses template to overload operator ->*

Great work. I love the fact that this encourages writing tests that are readable/documenting. Definitely gonna give this a try. Any recommended test runner to go with it?

There's a test runner included as a macro that defines main

Good to know, thanks!
