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 `_
* `Bitbucket `_
* `CircleCI `_
* `GitLab CI `_
* `Jenkins `_
* `TaskCluster `_
* `Travis CI `_

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.

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 `_ - Adds the
base URL to the metadata.
* `pytest-html `_ - Displays the
metadata at the start of each report.
* `pytest-reporter-html1 `_ -
Presents metadata as part of the report.
* `pytest-selenium `_ - Adds the
driver, capabilities, and remote server to the metadata.
