+## Testing
+
+The benchmark can be tested using pytest:
+
+```terminal
+pytest tests/examples/test_atomic_add_bench.py
+```
+
+This will run parametrized tests across different data types (int8, fp16, bf16, fp32), buffer sizes, and block sizes to ensure the atomic add functionality works correctly.
