══ Skipped tests (1) ═══════════════════════════════════════════════════════════
• Not run on non-mac platforms due to non-deterministic randomness in
implementation of std::uniform_int_distribution across different compilers.
Test cases were written only for macOS (clang). We have not had time to write
tests for other compilers like gcc yet. (1): 'test-GenMatch.R:68:1'
