pytest-poolwatch is an open-source pytest plugin designed to profile concurrency behavior and detect scheduler underfill in test runs. It provides insights into asyncio-based tests and xdist parallel execution, helping developers identify performance bottlenecks and resource under-utilization in their test suites. The tool is MIT-licensed and available on PyPI.
In the Testing & QA space, pytest-poolwatch takes a focused approach. It focuses on detecting under-utilization and concurrency issues in pytest test suites, especially with asyncio and xdist. It is built as an open-source project for developers. The project is open source (MIT). It runs on the command line.
pytest-poolwatch first shipped in 2026. The project is developed in the open on GitHub with 6 commits in the last 90 days. Key capabilities include Concurrency Profiling, Scheduler Analysis, and Asyncio Support.
