django tool for running tests organized between unit, functional and integration

branch: master
README.md

unclebob

Version 0.4.0

What

UncleBob is a simple django app that allow you writting per-app tests within these paths:

  • <appname>/tests/unit/test*.py - for unit tests
  • <appname>/tests/functional/test*.py - for functional tests
  • <appname>/tests/integration/test*.py - for integration tests

installing

first of all

pip install unclebob

add it to your django project

on settings.py

INSTALLED_APPS = (
    ...
    'unclebob',
    ...
)

TEST_RUNNER = 'unclebob.runners.Nose'
import unclebob
unclebob.take_care_of_my_tests()

running

just use the regular test command:

python manage.py test

running only the unit tests

python manage.py test --unit

running only the functional tests

python manage.py test --functional

running only the integration tests

python manage.py test --integration

running only a specific path

python manage.py test path/to/app/tests

or

python manage.py test path/to/app/tests/unit

warning:

if you run only the unit tests, then unclebob is NOT going to setup the test database. Since unit tests are supposed to be "unwired", what I mean is that unit tests MUST NOT make use of actual database, filesystem or network at all.

Instead, they must test isolated parts of your code.

For that reason, sir, Uncle Bob is gonna break your neck in case you decide to use those, so called, "external resources" in your unit tests.

although you can tell unclebob to never touch the database at all

in your settings.py

UNCLEBOB_NO_DATABASE = True

other aspects

1. it provides an environment variable, so that you'll know when unclebob is running

When unclebob is running tests, it sets the environment variable UNCLEBOB_RUNNING to the current working directory.

You can use it, for example, in your codebase fr avoiding logging during the tests.

Motivation

nose is such a really nice tool for writting tests on python.

Instead of using the unittest framework, which is builtin python thou is less fun to use.

And you know, the most joyable is the writting/running test experience, more developers will write tests for the project. And as much tests, better.

Naming

This project was named after Uncle Bob Martin, one of the agile manifesto chaps that brought code cleaness techniques and advices to the rest of us.

Something went wrong with that request. Please try again.
