pytest-metadata is a plugin for pytest that provides access to test session metadata.
You will need the following prerequisites in order to use pytest-metadata:
- Python 2.7, 3.6, PyPy, or PyPy3
To install pytest-metadata:
$ pip install pytest-metadataThe following metadata is gathered by this plugin:
| Key | Description | Example |
|---|---|---|
| Python | Python version | 3.6.4 |
| Platform | Platform | Darwin-17.4.0-x86_64-i386-64bit |
| Packages | pytest packages | {'py': '1.5.2', 'pytest': '3.4.1'} |
| Plugins | pytest plugins | {'metadata': '1.6.0'} |
You can provide your own metadata (key, value pair) by specifying --metadata on the commandline:
pytest --metadata foo barNote: You can provide multiple sets of --metadata:
pytest --metadata foo bar --metadata baz zooWhen run in a continuous integration environment, additional metadata is added from environment variables. Below is a list of the supported continuous integration providers, along with links to the environment variables that are added to metadata if they're present.
Note that if you're using Tox to run your tests then you will need to pass down any additional environment variables for these to be picked up.
If you pass --verbose on the command line when running your tests, then the metadata will be displayed in the terminal report header:
pytest --verbose

plugins: metadata-1.6.0To add/modify/delete metadata at the end of metadata collection, you can use the pytest_metadata hook:
import pytest
@pytest.mark.optionalhook
def pytest_metadata(metadata):
for key in metadata.keys():
if "password" in key.lower():
del metadata[key]To access the metadata from a test or fixture, you can use the metadata fixture:
def test_metadata(metadata):
assert 'metadata' in metadata['Plugins']To access the metadata from a plugin, you can use the _metadata attribute of the config object. This can be used to read/add/modify the metadata:
def pytest_configure(config):
if hasattr(config, '_metadata'):
config._metadata['foo'] = 'bar'Here's a handy list of plugins that either read or contribute to the metadata:
- pytest-base-url - Adds the base URL to the metadata.
- pytest-html - Displays the metadata at the start of each report.
- pytest-selenium - Adds the driver, capabilities, and remote server to the metadata.
