#!/bin/bash
# runTests.sh
#
# Single entry point for the repository's evidence suite. Runs the
# pure-C unit tests, verification cases (exact-solution comparisons), and then
# the smoke test (compiles and integrates a few dozen steps, compares against
# nothing).
#
# Usage:
#   bash runTests.sh                    # unit, verification, then smoke tests
#   bash runTests.sh --unit             # central-film observer unit tests only
#   bash runTests.sh --verification     # verification cases only
#   bash runTests.sh --smoke            # smoke test only
#
# Environment:
#   VERIFICATION_THREADS=N  Build the verification cases with -fopenmp and
#                           run them on N threads. Serial by default, because
#                           a recorded verification result should be bitwise
#                           reproducible. The full serial suite is dominated
#                           by staticFilmTube (about 49 min; 10 min on 16
#                           threads).
