A Django TestRunner for the Behave BDD module

Tested on:

• Python 2.7
• Python 3.3, 3.4
• Django v1.6-1.11

This is a fork of django-behave/django-behave which supports testing of apps in subdirectories.

The app loading mechanism only supports Django version 1.6 and higher

django-behave

A Django TestRunner for the Behave BDD module

GOALS

• To provide a Cucumber-compatible BDD toolset for Django;
• To work well with existing Django testing behaviour e.g. use a test database
• To use Cucumber/Gherkin syntax.
• To provide a library of django-useful steps.

HOW TO USE

• add django_behave to INSTALLED_APPS
• set TEST_RUNNER to django_behave.runner.DjangoBehaveTestSuiteRunner or django_behave.runner.DjangoBehaveOnlyTestSuiteRunner
• add features directories to apps
• decide which automation library you want to use
• setup your environment.py to use this library to open browser (see below)
• copy django_behave/features/steps/library.py, if wanted.

EXAMPLE

Assuming you have an app called proj.apps.myapp:

Edit INSTALLED_APPS, as above. Edit TEST_RUNNER, as above.

Create proj/apps/myapp/features and proj/apps/myapp/features/steps.

Copy example_app/features/tutorial.feature to the features dir. Copy example_app/features/steps/tutorial.py to the features/steps dir.

$ python manage.py test myapp

should then show you django-behave in action, finding the tutorial feature and running the tests.

REQUIREMENTS

The main one is the 'behave' module, of course, which provides the BDD toolset for Python.

Also used are:

• django >= 1.6
• selenium

See requirements.txt for details.

AUTOMATION LIBRARY

django_behave is agnostic about which automation library you use inside the tests.

I (Rachel, original author of django-behave) like splinter (https://splinter.readthedocs.org/).

You will need to setup a browser for use with this library.

For example, my features/environment.py file has this:

from splinter.browser import Browser

def before_all(context):
    context.browser = Browser()

def after_all(context):
    context.browser.quit()
    context.browser = None

COMMAND LINE OPTIONS

It is possible to use Behave command line options. In order to avoid conflict with Django's manage.py test options, all options meant for django-behave start with '--behave_'. For example, given the following Behave command:

behave --no-color --tags @mytag ...

this would become:

./manage.py test --behave_no-color --behave_tags @mytag ...

In addition, the option '--behave_browser' can allow the user to specify which browser to use for testing. For example:

./manage.py test --behave_browser firefox ...

The splinter before_all() example above could then use this option:

def before_all(context):
    context.browser = Browser(context.config.browser)

TESTING

You can run all unittest2 tests with the following:

python tests.py

The tests use the example_proj project which has installed the example_app application.

If you're using a virtualenv, activate it before running this command, otherwise it will fail.
