Fortran test frameworks

January 4, 2025

Unit test frameworks should be lightweight to setup and maintain. End users should be able to easily run the unit and integration tests themselves as part of a typical end-user install.

The simplest approach is to write several small test programs and execute them using CMake or Meson. This method can also be an appropriate choice where the program uses complex library interactions that may not mix well with a generic test framework.

The Veggies Fortran test framework is an example of a Fortran unit testing framework. Check the Fortran-lang group for a contemporary discussion on Fortran test frameworks.
