pytest plugin with mechanisms for echoing environment variables, package version and generic attributes

Project description

PyPI package

Print environment variables, package version and generic attributes, as they are at the beginning of the test.

Useful in the continuous integration to dump test configuration/environment and or to check if attributes are properly set (ie. you change environment with os.environ)

Install

install via:

pip install pytest-echo

Examples

Dump environment variables

$ pytest --echo-env=HOME
============================= test session starts =========================
platform linux2 -- Python 2.7.4 -- py-1.4.22 -- pytest-2.6.0 -- /bin/python
Environment:
    HOME: /Users/sax
plugins: echo, pydev, cov, cache, django

Dump package version

$ pytest --echo-version=pytest_echo
============================= test session starts =========================
platform linux2 -- Python 2.7.4 -- py-1.4.22 -- pytest-2.6.0 -- /bin/python
Package version:
    pytest_echo: 0.1
plugins: echo, pydev, cov, cache, django

Warning

The first attempt to retrieve the version is done via setuptools if it fails, the module is imported (__import__(package)) to retrieve the version reading get_version, __version__, VERSION, version so any module level code is executed. This should be not an issue as no problematic code should be present in the first level of the package

Dump attributes

$ pytest --echo-attr=django.conf.settings.DEBUG
============================= test session starts =========================
platform linux2 -- Python 2.7.4 -- py-1.4.22 -- pytest-2.6.0 -- /bin/python
Inspections
    django.conf.settings.DEBUG: False
plugins: echo, pydev, cov, cache, django

Warning

Be careful when use --echo-attr. It loads any module in the path and this will execute any module level code If you try to dump a property, related getter will be executed.

Note

You cannot dump callable result.

Configure via tox.ini/setup.cfg/pytest.cfg

Example of use in a django project:

[pytest]
addopts = -vvv
        --tb=short
        --capture=no
        --echo-env PWD
        --echo-env VIRTUAL_ENV
        --echo-env DBENGINE
        --echo-version django
        --echo-version pip
        --echo-version pytest-echo
        --echo-attr django.conf.settings.DATABASES.default.ENGINE
$ pytest

Globbing

Starting from version 1.5, is possible to glob packages version and environment variables, as:

$ pytest --echo-version=pytest-* --echo-env=VIRTUAL*

or

[pytest]
addopts = -vvv
        --echo-env VIRTUAL*
        --echo-version pytest-*
