Py.test Virtualenv Fixture
==========================

Create a Python virtual environment in your test that cleans up on
teardown. The fixture has utility methods to install packages and list
what’s installed.

Installation
------------

Install using your favourite package installer:

.. code:: bash

       pip install pytest-virtualenv
       # or
       easy_install pytest-virtualenv

Enable the fixture explicitly in your tests or conftest.py (not required
when using setuptools entry points):

.. code:: python

       pytest_plugins = ['pytest_virtualenv']

Configuration
-------------

This fixture is configured using the following evironment variables

+-------------------+------------------------------+-------------------+
| Setting           | Description                  | Default           |
+===================+==============================+===================+
| VIRTUALENV_F      | Which virtualenv executable  | ``virtualenv``    |
| IXTURE_EXECUTABLE | will be used to create new   |                   |
|                   | venvs                        |                   |
+-------------------+------------------------------+-------------------+

Fixture Attributes
------------------

Here’s a noddy test case to demonstrate the basic fixture attributes.
For more information on ``path.py`` see https://pathpy.readthedocs.io/

.. code:: python

   def test_virtualenv(virtualenv):
       # the 'virtualenv' attribute is a `path.py` object for the root of the virtualenv
       dirnames = virtualenv.virtualenv.dirs()
       assert {'bin', 'include', 'lib'}.intersection(set(dirnames))
       
       # the 'python' attribute is a `path.py` object for the python executable
       assert virtualenv.python.endswith('/bin/python')

Installing Packages
-------------------

You can install packages by name and query what’s installed.

.. code:: python

   def test_installing(virtualenv):
       virtualenv.install_package('coverage', installer='pip')
       
       # installed_packages() will return a list of `PackageEntry` objects.
       assert 'coverage' in [i.name for i in virtualenv.installed_packages()]

Developing Source Checkouts
---------------------------

Any packages set up in the *test runner’s* python environment (ie, the
same runtime that ``py.test`` is installed in) as source checkouts using
``python setup.py develop`` will be detected as such and can be
installed by name using ``install_package``. By default they are
installed into the virtualenv using ``python setup.py develop``, there
is an option to build and install an egg as well:

.. code:: python

   def test_installing_source(virtualenv):
       # Install a source checkout of my_package as an egg file
       virtualenv.install_package('my_package',  build_egg=True)

Running Commands
----------------

The test fixture has a ``run`` method which allows you to run commands
with the correct paths set up as if you had activated the virtualenv
first.

.. code:: python

   def test_run(virtualenv):
       python_exe_path  = virtualenv.python
       runtime_exe = virtualenv.run("python -c 'import sys; print sys.executable'", capture=True)
       assert runtime_exe == python_exe_path

Running Commands With Coverage
------------------------------

The test fixture has a ``run_with_coverage`` method which is like
``run`` but runs the command under coverage *inside the virtualenv*.
This is useful for capturing test coverage on tools that are being
tested outside the normal test runner environment.

.. code:: python

   def test_coverage(virtualenv):
       # You will have to install coverage first
       virtualenv.install_package(coverage)
       virtualenv.run_with_coverage(["my_entry_point", "--arg1", "--arg2"])
