# Test Filter Standardization

# Wires every rocRAND test binary into the shared rocm-libraries CTest
# categorization (see ${ROCM_LIBRARIES_ROOT}/shared/ctest/). For each tracked
# test target we register one extra CTest entry per category defined in
# test_categories.yaml. Each entry invokes the binary with a
# `--gtest_filter=...` derived from the YAML, and is tagged with the category
# labels and timeout. This lets users select tiers via standard ctest labels:
#
#   ctest -L quick       # fast sanity checks
#   ctest -L standard    # full gtest run
#
# The original per-binary tests added by add_relative_test() above are kept
# untouched, so existing workflows are not affected.
