https://github.com/pytest-dev/pytest-metadata/issues/70 We use `pytest-json-report` and recently found that the "Environement" section of the json reports are always empty. From [release note](https://github.com/pytest-dev/pytest-metadata/blob/master/CHANGES.rst) of `pytest-metadata` 3.0.0: > Use pytest.stash internally instead of _metadata It seems `pytest-json-report` needs to be updated to cope with `pytest-metadata`'s breaking change.
