# run_tests.sh — sequential test runner for the C++ binding.
#
# Discovers every binary under tests/build/ produced by `make tests`
# and runs them one at a time, mirroring the C binding's runner.
# Catch2 v3's default reporter prints PASS / FAIL per test case; this
# wrapper aggregates the per-binary exit codes.
#
# Usage:
#   make tests && ./run_tests.sh
#   ITB_TEST_FILTER='blake3' ./run_tests.sh   # passes filter to Catch2
