Docker images
From FISPACT-II Wiki
From version 4.0 (2018), FISPACT-II is automatically built and tested using Docker containers. This allows the code to be rigorously tested on multiple (over 100) operating systems/versions and with different compilers - all within a continuous integration framework and without manual intervention.
FISPACT-II has been built and tested on all of the images available on the FISPACT-II Docker Hub, with regression tests performed using those tagged with _data. The suite of system test inputs/outputs have been drawn from these automated regression tests and users can verify results from their own system against reference results from the suite.
