A py.test plugin providing access to vagrant.

Project description

https://badge.fury.io/py/pytest-vagrant.svg

pytest-vagrant provides a py.test fixture for working with vagrant in pytest.

Installation

To install pytest-vagrant:

pip install pytest-vagrant

Usage

To make it easy to use in with pytest the Vagrant object can be injected into a test function by using the vagrant fixture.

Example:

def test_run_fail(vagrant):
    machine = vagrant.from_box(
        box="hashicorp/bionic64", name="pytest_vagrant", reset=False)

    with machine.ssh() as ssh:
        ssh.run("some_command")

The vagrant argument is an instance of Vagrant and represents the vagrant environment on the machine running the test code.

Relase new version

  1. Edit NEWS.rst and wscript (set correct VERSION)

  2. Run

    ./waf upload
    

Source code

The main functionality is found in src/vagrant.py and the corresponding unit test is in test/test_vagrant.py if you want to play/modify/fix the code this would, in most cases, be the place to start.

Developer Notes

We try to make our projects as independent as possible of a local system setup. For example with our native code (C/C++) we compile as much as possible from source, since this makes us independent of what is currently installed (libraries etc.) on a specific machine.

To “fetch” sources we use Waf (https://waf.io/) augmented with dependency resolution capabilities: https://github.com/steinwurf/waf

The goal is to enable a work-flow where running:

./waf configure
./waf build --run_tests

Configures, builds and runs any available tests for a given project, such that you as a developer can start hacking at the code.

For Python project this is a bit unconventional, but we think it works well.

Tests

The tests will run automatically by passing --run_tests to waf:

./waf --run_tests

This follows what seems to be “best practice” advise, namely to install the package in editable mode in a virtualenv.
