Root Cause

pytest-html plugin did not generate the report file, often because the plugin is not installed, the output path is incorrect, or the test run crashed before report generation.

generic

中文

pytest-html 插件未生成报告文件，通常是因为插件未安装、输出路径不正确，或测试运行在报告生成前崩溃。

Workarounds

  1. 95% success 
    pip install pytest-html
pytest --html=report.html --self-contained-html
  2. 88% success 
    import tempfile
import os

report_path = os.path.join(tempfile.gettempdir(), 'report.html')
# Run pytest with: --html=report_path

Dead Ends

Common approaches that don't work:

  1. 95% fail

    This creates an empty file that does not contain test results. The report will be useless.

  2. 90% fail

    This avoids the error but does not generate the report, defeating the purpose of using pytest-html.
