Root Cause

pytest-benchmark plugin is not installed or not loaded, so the benchmark fixture is unavailable. This can also happen if the plugin is disabled in pytest.ini.

generic

中文

pytest-benchmark 插件未安装或未加载，因此 benchmark 夹具不可用。如果插件在 pytest.ini 中被禁用，也可能发生这种情况。

Workarounds

  1. 95% success 
    pip install pytest-benchmark
pytest --benchmark-only
  2. 90% success 
    # pytest.ini
[pytest]
# Remove -p no:benchmark if present
addopts = -p benchmark

Dead Ends

Common approaches that don't work:

  1. 90% fail

    This shadows the plugin's fixture and does not provide benchmarking functionality. The test will not actually benchmark anything.

  2. 75% fail

    This provides raw timing but lacks statistical analysis, warmup, and comparison features of pytest-benchmark.
