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.
