Root Cause

pytest-benchmark is not installed, so the 'benchmark' fixture it provides is unavailable. Common when copying benchmark tests into a repo without the dev dependency.

generic

中文

未安装 pytest-benchmark，因此它提供的 'benchmark' fixture 不可用。常见于将 benchmark 测试复制到未安装开发依赖的仓库。

Workarounds

  1. 97% success 
    pip install pytest-benchmark

# then
def test_sort(benchmark):
    result = benchmark(sorted, list(range(1000)))
    assert result[0] == 0
  2. 90% success 
    import pytest

pytest.importorskip('pytest_benchmark')

def test_sort(benchmark):
    benchmark(sorted, list(range(1000)))

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Provides no timing, statistics, or comparison; the test gives false confidence.

  2. 70% fail

    No integration with pytest reporting, no --benchmark-compare, and noisy CI output.
