Integration with other test frameworks

[ThibaultLemaire]

Is there a piece of documentation explaining how to integrate libassert into other test frameworks?

I'd like to avoid aborting on assertions failed and instead report the error to the test framework.

To answer my own question: I found most of what I needed in the existing implementations for GTest and Catch2.

TL;DR:

libassert::set_failure_handler(
    [](const libassert::assertion_info& info) { /* your handler code here */ });

There isn't any documentation for this. The gtest and catch2 integrations are kind of experimental and it's kind of a miracle they were able to happen, it took a lot of pouring over documentation to figure out how to generate custom failures. I would welcome something in the documentation outlining the general strategy of a custom failure handler in a context like this though.

I've added a customization point which will help with using libassert assertions with testing libraries. I'll close this with the next release.
