In April 2026, the team delivered a focused improvement to the testing infrastructure for the neuro-san-studio project, enabling asyncio-aware tests to run reliably. By configuring pytest to use an asyncio event loop in pytest.ini, async components can be tested more deterministically, reducing flaky tests and accelerating feedback. This lays groundwork for safer refactors and future async features. The change is implemented in cognizant-ai-lab/neuro-san-studio (commit 1503f8b68671023003d9a550b1fa7d8d070c6ef0). Overall impact: improved test reliability for asynchronous code, smoother integration with CI, and a stronger foundation for scalable async development. Technologies demonstrated: Python, pytest, asyncio, pytest.ini configuration, and test infrastructure design.
