Worked on the amazon-braket-sdk-python repository, focusing on enhancing the quality and maintainability of unit tests for one-qubit property assertions. Applied test-driven development principles and Python expertise to refactor existing tests, making assertions clearer and the test suite easier to maintain. This targeted update established a more robust baseline for validating critical qubit properties, which supports faster iteration and reduces future maintenance overhead. By improving test readability and structure, the work enables developers and collaborators to more efficiently update and extend the SDK. No major bugs were addressed during this period, with efforts concentrated on strengthening test reliability and maintainability.
