# Runs two standard decks that carry a `test_problem` id and lets the upstream
# driver (driver/report.cpp) compare the final total kinetic energy against its
# hard-coded reference value (tolerance: within 0.001 %):
#   InputDecks/clover_bm_short.in    test_problem 2  (960 x 960,   87 steps, KE ref 1.19316898756307)
#   InputDecks/clover_bm16_short.in  test_problem 4  (3840 x 3840, 87 steps, KE ref 0.307475452287895)
# Each run must exit 0 and print "This test is considered PASSED".
# Prints PASS/FAIL at the end; exit code 0/1.
