It groups runs into rounds, automatically adjusting iteration counts to produce stable measurements, and generates comparison reports and histograms. The package integrates directly into pytest's test discovery and reporting, so you write benchmarks as normal test functions that receive a `benchmark` fixture.\n\nThe plugin is designed for function-level micro-benchmarking and provides both simple mode (pass a function and arguments) and pedantic mode with explicit control over setup, iterations, rounds, and per-round teardown. It collects CPU info via py-cpuinfo and supports profiling, tracing, and cProfile integration. Results can be compared across runs and exported to CSV.","worth_installing":"Yes. pytest-benchmark is actively maintained, has no known vulnerabilities, low install friction, and a permissive license. It is the standard tool for pytest-based performance testing and is well-suited for any project that needs to track or optimize function-level performance."},"id":"pytest-benchmark","links":{"html":"https://skillfed.io/packages/pytest-benchmark","md":"https://skillfed.io/packages/pytest-benchmark.md","pypi":"https://pypi.org/project/pytest-benchmark/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-11-09","license_spdx":"BSD-2-Clause","license_treatment":"permissive","name":"pytest-benchmark","python_support":"supports_current","summary":"A ``pytest`` fixture for benchmarking code.
