About Fortuno

Fortuno is a flexible and extensible unit testing framework tailored for modern Fortran programming. Its name is an acronym for “Fortran Unit-Testing Objects”, but also hints at the Esperanto word “fortuno” (fortune), symbolizing its goal of bringing success to Fortran developers and to their (hopefully) well tested projects.

Fortuno offers a simple, user-friendly interface requiring only minimal amount of boiler-plate code when writing unit tests. It puts strong emphasis on modularity and extensibility, providing a robust foundation for creating customized unit testing environments. Fortuno is written in Fortran 2018.

The framework supports a variety of testing styles and scenarios, including:

• straightforward unit tests for basic validation,

• fixtured tests initializing and finalizing test environments,

• parameterized tests that allow for varied input testing within the same test structure,

• nestable test containers with configurable initializers and finalizers to structure large test sets,

• serial unit testing for serial and OpenMP-threaded applications,

• parallel unit testing tailored for MPI- and coarray-parallelized projects, and

• smooth integration with various build systems (fpm, CMake and Meson).

Fortuno is an open source, community developed project. You can follow and join the development on the Fortuno project page on GitHub.
