# Usage: run_unit_tests.sh [TEST_DIR] [BUILD_CONFIG]
#   TEST_DIR      directory containing the built tests (default: build/tests)
#   BUILD_CONFIG  configuration to run; required for multi-config generators
#                 (Windows/macOS), harmless/omitted for single-config (Linux).

# no numpy, so those tests SKIP without it. Install it into that interpreter's own
# site-packages -- no PYTHONPATH needed, and re-checked every run because a rebuild of
# the test target wipes and re-copies the runtime. Needs network on the first run only;
# a failure here is not fatal, the tests just keep skipping.
