django-selenium-test-runner

django-selenium-test-runner incorporates functional testing into Django’s manage.py test subcommand using Selenium web testing tools.

Background

This package was made to facilitate and simplify functional testing in Django using Selenium tools.
Selenium tests are code that emulate a user/web browser interaction allowing automatic web server testing. These tests can be created using selenium-ide and exported as python files for this test runner to use them. Selenium-ide allows to record in real time a user interaction with a web browser, in a similar way as a macro recorder in word processing applications.
Fixtures are fixed data fed into the database at the beginning of each test run. The idea is that each test run against a consistent predefined state. Fixtures can be created using manage.py dumpdata [options] [appname ...]

Installation

If you have setuptools installed, you can simply run the following command: 
sudo easy_install django-selenium-test-runner
If you downloaded the package, you can just unpack it with: 
tar zxvf django-selenium-test-runner-0.1.0.tar.gz
and copy “dstest” directory tree to Python’s site-packages directory, which is usually located at: 
  /usr/lib/python2.4/site-packages (Unix, Python 2.4)
  /usr/lib/python2.5/site-packages (Unix, Python 2.5)
  /usr/lib/python2.6/dist-packages (Unix, Python 2.6)
django-selenium-test-runner is enabled in the project’s settings.py with: 
TEST_RUNNER = 'dstest.test_runner.run_tests'

Usage

Both, django unittest and selenium tests will be run with the standard command: 
python manage.py test [options] [appname ...]
The exported selenium tests will be searched in django_app_dir/tests/selenium/ directories where django_app_dir is an application defined in INSTALLED_APPS. This default can be changed with the setting SELENIUM_TESTS_PATH. Test names start with "test". As these tests will be imported, please be sure to create django_app_dir/tests/init.py and django_app_dir/tests/selenium/init.py files as any python package.
Fixture data is loaded by default from django_app_dir/fixtures/tests/data.json at the beginning of each selenium test. This default can be change using the FIXTURES setting.

Settings

There is only one required setting into your project’s settings.py, assuming django-selenium-test-runner is correctly installed:
TEST_RUNNER = ‘dstest.test_runner.run_tests’
optional settings are:
  • SELENIUM_TESTS_PATH - Changes default directories to look for Selenium testswithin the application directories. (Default: ‘tests/selenium’)
  • FIXTURES - List of fixture files to load within the django_app_dir/fixturesdirectories. (Default: [‘tests/data.json’])
  • SELENIUM_PATH - Directory path for Selenium RC jar its python driver(i.e.: selenium-server.jar and selenium.py) (Default: path where django-selenium-test-runner/dstest is installed)

Testing the package

django-selenium-test-runner comes with its own test suite based on the Django tutorial. It is designed to serve as example in a Django admin application, and showcase django-selenium-test-runner capabilities. To run it, cd into the tests directory of the package and execute: 
python runtests

Dependencies

Most dependencies are integrated in the django-selenium-test-runner package. For now, either Sqlite 3 or Postgres is required as more testing is needed to make it database agnostic.
