Available metadata
The 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'}
======== =============== ===================================
Additional metadata
You can provide your own metadata (key, value pair) by specifying --metadata
on the commandline::
pytest --metadata foo bar
Note: You can provide multiple sets of --metadata
::
pytest --metadata foo bar --metadata baz zoo
There's also the possibility of passing in metadata as a JSON string::
pytest --metadata-from-json '{"cat_says": "bring the cat nip", "human_says": "yes kitty"}'
Alternatively a JSON can be read from a given file::
pytest --metadata-from-json-file path/to/valid/file.json
Continuous integration
When 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.
AppVeyor <https://www.appveyor.com/docs/environment-variables/>
_Bitbucket <https://confluence.atlassian.com/bitbucket/environment-variables-794502608.html>
_CircleCI <https://circleci.com/docs/1.0/environment-variables/>
_GitLab CI <http://docs.gitlab.com/ce/ci/variables/README.html>
_Jenkins <https://wiki.jenkins-ci.org/display/JENKINS/Building+a+software+project#Buildingasoftwareproject-JenkinsSetEnvironmentVariables>
_TaskCluster <https://docs.taskcluster.net/reference/workers/docker-worker/environment>
_Travis CI <https://docs.travis-ci.com/user/environment-variables/>
_
Note that if you're using Tox <http://tox.readthedocs.io/>
_ to run your tests
then you will need to pass down any additional environment variables <http://tox.readthedocs.io/en/latest/example/basic.html#passing-down-environment-variables>
_
for these to be picked up.
Viewing metadata
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
============================ test session starts ============================
platform darwin -- Python 3.6.4, pytest-3.4.1, py-1.5.2, pluggy-0.6.0 -- /usr/bin/python
cachedir: .pytest_cache
metadata: {'Python': '3.6.4', 'Platform': 'Darwin-17.4.0-x86_64-i386-64bit', 'Packages': {'pytest': '3.4.1', 'py': '1.5.2', 'pluggy': '0.6.0'}, 'Plugins': {'metadata': '1.6.0'}}
plugins: metadata-1.6.0
Including metadata in Junit XML
Pytest-metadata provides the session scoped fixture :code:include_metadata_in_junit_xml
that you may use to include any metadata in Junit XML as property
tags.
For example the following test module
.. code-block:: python
import pytest
pytestmark = pytest.mark.usefixtures('include_metadata_in_junit_xml')
def test():
pass
when called with
.. code-block:: bash
pytest --metadata Daffy Duck --junit-xml=results.xml
would produce the following XML
.. code-block:: xml
...
Accessing metadata
To add/modify/delete metadata at the end of metadata collection, you can use the pytest_metadata
hook:
.. code-block:: python
import pytest
@pytest.hookimpl(optionalhook=True)
def pytest_metadata(metadata):
metadata.pop("password", None)
To access the metadata from a test or fixture, you can use the metadata
fixture:
.. code-block:: python
def test_metadata(metadata):
assert 'metadata' in metadata['Plugins']
To access the metadata from a plugin, you can use the stash
attribute of
the config
object. This can be used to read/add/modify the metadata:
.. code-block:: python
def pytest_configure(config):
metadata = config.pluginmanager.getplugin("metadata")
if metadata:
from pytest_metadata.plugin import metadata_key
config.stash[metadata_key]['foo'] = 'bar'
Plugin integrations
Here's a handy list of plugins that either read or contribute to the metadata:
pytest-base-url <https://pypi.python.org/pypi/pytest-base-url/>
_ - Adds the
base URL to the metadata.pytest-html <https://pypi.python.org/pypi/pytest-html/>
_ - Displays the
metadata at the start of each report.pytest-reporter-html1 <https://pypi.org/project/pytest-reporter-html1/>
_ -
Presents metadata as part of the report.pytest-selenium <https://pypi.python.org/pypi/pytest-selenium/>
_ - Adds the
driver, capabilities, and remote server to the metadata.
