QDP Core Test Suite

Unit tests for QDP core library covering input validation, API workflows, and memory safety.

Test Files​

validation.rs - Input Validation​

  • Invalid encoder strategy rejection
  • Qubit size validation (mismatch, zero, max limit 30)
  • Empty and zero-norm data rejection
  • Error type formatting
  • Non-Linux platform graceful failure

api_workflow.rs - API Workflow​

  • Engine initialization
  • Amplitude encoding with DLPack pointer management

memory_safety.rs - Memory Safety​

  • Memory leak detection (100 encode/free cycles)
  • Concurrent state vector management
  • DLPack tensor metadata validation

examples/dataloader_throughput.rs - DataLoader Batch Throughput​

  • Simulates a QML training loop that streams batches of 64 vectors
  • Producer/consumer model with configurable prefetch to avoid GPU starvation
  • Reports vectors-per-second to verify QDP keeps the GPU busy
  • Run: cargo run -p qdp-core --example dataloader_throughput --release
  • Environment overrides: BATCHES=<usize> (default 200), PREFETCH=<usize> (default 16)

common/mod.rs - Test Utilities​

  • create_test_data(size): Generates normalized test data

Running Tests​

# Run all tests
cargo test --package qdp-core

# Run specific test file
cargo test --package qdp-core --test validation
cargo test --package qdp-core --test api_workflow
cargo test --package qdp-core --test memory_safety

Requirements​

  • Linux OS (tests skip on other platforms)
  • CUDA-capable GPU (tests skip if unavailable)
  • Rust toolchain with CUDA support
