pytest-metadata is described as a plugin for pytest that provides access to test session metadata. 
That is such a humble description for such a massively useful plugin. 
If you're already using pytest-html, you have pytest-metadata already installed, as pytest-metadata is one of the dependencies for pytest-html.
However, pytest-metadata is very useful even on its own.

• pytest-base-url - Adds the base URL to the metadata.
• pytest-html - Displays the metadata at the start of each report. 
  • See S2:E6: pytest-html - a plugin that generates HTML reports for test results
• pytest-reporter-html1 - Presents metadata as part of the report.
• pytest-selenium - Adds the driver, capabilities, and remote server to the metadata.

If you've got other plugins that work well with pytest-metadata, please let me know.
