Apache Mahout Testing Suite

This directory contains the unified test suite for Apache Mahout, covering both the Qumat quantum computing library and the QDP (Quantum Data Plane) GPU-accelerated components.

Test Structure

├── qumat/              # Qumat backend tests
├── qdp/                # QDP tests (GPU-required)
├── utils/              # Shared test utilities
└── conftest.py         # Pytest configuration and fixtures

To run QDP test

Before running QDP tests, build the _qdp module into the main venv:

uv run --active maturin develop --manifest-path qdp/qdp-python/Cargo.toml

Then run the tests:

uv run pytest testing/qdp/ -v

Running Tests

# Run all tests
pytest

# Run with verbose output
pytest -v

# Run only Qumat tests (works without GPU)
pytest testing/qumat/

# Run only QDP tests (requires GPU and built extension)
pytest testing/qdp/

# Run specific test file
pytest testing/qumat/test_create_circuit.py

# Run tests matching a pattern
pytest -k "hadamard"

# Run tests for a specific backend
pytest -k "qiskit" testing/qumat/

QDP Test Handling

QDP-related tests are automatically skipped when the QDP extension or a compatible GPU is not available.

• QDP tests do not block running the Qumat test suite
• Contributors without CUDA GPUs can run all Qumat tests normally
• QDP tests are only executed when the required extension and hardware are available
