Synergies with Fortuno?

[aradi]

Hi guys,

I just wanted to ask around, whether there is any interest in exploring synergies with the Fortuno unit testing framework. (Disclaimer: I am the main author of Fortuno).

Fortuno is a unit testing system which is capable to test also MPI- and coarray- parallelized routines (being, to my knowledge, the only test system offering all those capabilities in one framework).

I have actually discussed with @awvwgk 2022 in Darresburry about possible synergies with test-drive, but then decided for an independent development for following two reasons:

• Fortuno tries to use modern Fortran constructs, wherever it makes sense. (I would like to make it also a project demonstrating best practices, as far as possible.) At the beginning, they were hardly any compilers which could build it correctly, so it could not be considered as a project for wider audience. The situation changed since then, as due to workarounds I managed to make Fortuno "compatible" with gcc 13 & 14 (without obtaining false positives on memory leaks 😉 ), with Intel 2024 and 2025 and NAG 7.2. And it seems, that also flang has no problems any more to build it.

• The current structure of test-drive is not really appropriate for testing parallel routines in my opinion. Fortuno, however, is flexible enough now, that one could emulate the test-drive way of writing tests for serial tests. (In case somebody wanted to write tests with a mandatory dummy argument instead of simply writing test subroutines without any arguments 😉 )

Anyway, I'd love to hear your opinion on it. I would be definitely interested in uniting forces and resources to have a versatile unit testing system serving the needs of the community. I think, by offering versatile MPI- and coarray parallel unit testing frameworks, we would be even ahead of test frameworks in other, more recognized programming languages.
