OpenMC Test Suite

The purpose of this test suite is to ensure that OpenMC compiles using various combinations of compiler flags and options and that all user input options can be used successfully without breaking the code. The test suite is based on regression or integrated testing where different types of input files are configured and the full OpenMC code is executed. Results from simulations are compared with expected results. The test suite is comprised of many build configurations (e.g. debug, mpi, hdf5) and the actual tests which reside in sub-directories in the tests directory.

The test suite is designed to integrate with cmake using ctest. To run the full test suite run:

python run_tests.py

The test suite is configured to run with cross sections from NNDC. To download these cross sections please do the following:

cd ../data
python get_nndc.py
export CROSS_SECTIONS=<path_to_data_folder>/nndc/cross_sections.xml

The environmental variable CROSS_SECTIONS can be used to quickly switch between the cross sections set for the test suite and cross section set for your simulations.

A subset of build configurations and/or tests can be run. To see how to use the script run:

python run_tests.py --help

As an example, say we want to run all tests with debug flags only on tests that have cone and plot in their name. Also, we would like to run this on 4 processors. We can run:

python run_tests.py -j 4 -C debug -R "cone|plot"

Note that standard regular expression syntax is used for selecting build configurations and tests. To print out a list of build configurations, we can run:

python run_tests.py -p
