Mar 1, 2025March 2025: Strengthened testing foundations and expanded QA coverage for Classiq-library. Delivered a comprehensive overhaul of test infrastructure, including reformatting tests, updating notebooks, adjusting timeouts, and aligning conventions, which reduced flaky failures and improved maintainability. Added extensive quantum-algorithm and tutorials tests (e.g., Bernstein-Vazirani, prepare_state, exponentiation, Hamiltonian simulation with block-encoding, MCX, learning optimization, and QML guides), broadening confidence in core functionality. Fixed stability issues across notebooks, current working directory handling, and patch-related timeouts; introduced Pytest duration tracking to quantify performance and guide optimizations. Improved fidelity for HHL tests and introduced new configuration flag allow_zero_size to control edge-case behavior. Expanded QA tooling with notebook automation framework (ensuring notebooks are tested, plus a script to update outputs) and launched QMOD Workshop tests, while cleaning up legacy workshop code. Overall, these efforts deliver faster, more reliable releases and clearer guidance for developers and users.
