"""
This Python test basically does the same as the reduction
of one FE part in the folder `../../../solverTests/CarSuspension`.
It therefore reuses the input-files from that folder.

The test uses two environment variables:
    FEDEM_REDUCER = Full path to the reducer shared object library
    TEST_DIR = Full path to the parent folder of the solver tests
