Remote scenario setup for e2e testing of django projects
The full documentation will be at https://django-remote-scenario.readthedocs.org.
Install django-remote-scenario:
pip install django-remote-scenario
Then add it to an existing django project:
INSTALLED_APPS = [ ... django_rs
Inside your settings file you also need to add the following:
SETTINGS_FILE_PATH = __file__
You need to add django_rs urls to your project url file like this:
urlpatterns = patterns('',
...
url(r'^drs/', include('django_rs.urls')),
..
)
To create custom scenarios, just create a directory inside your app named "scenarios" , then add as many files as scenarios you want to implement and create a __init__.py so it becomes a module . Inside each of those files, you need to implement a main() function setting up the models you want to create for the scenario, you could create them by hand or use something like django_dynamic_fixtures https://github.com/paulocheque/django-dynamic-fixture
Once everything is ready, start the server this way, this will enable the dynamic call of scenarios:
python manage.py rune2eserver initial_data.json
Note: You need to pass a initial fixture file with the barebones of your data.
it is also possible (but not mandatory) to pass a specific settings file, for testing purposes, in case you want to do the tests using a different database for example:
python manage.py rune2eserver initial_data.json --settings=demoproject.test_settings [fixture1 fixture2....] [--addrport ipaddress:port]
You might also use you existing database to load scenarios on top of it with the "--skip-test-db" or "-t" modifier:
python manage.py rune2eserver -t initial_data.json
To start using it, just go to the following url:
http://127.0.0.1:8000/drs/[APPLICATION]/[SCENARIO]
after doing that the database will be populated with the data you provided in your scenario. Take into account that, everytime you call an scenario, all the other data in the database is erased, except for the one in your initial_data fixture files, wich are loaded again, and also the one you pass as a parameter when you call the command.
Inside this repository you will find a demo Django project preconfigured with a simple scenario that sets up four objects. Use it like this:
First run the server:
$ python manage.py rune2eserver initial_data.json --settings=demoproject.test_settings
Then go to your browser and setup a scenario:
http://127.0.0.1:8000/drs/demoapp/scenario_1
You may also pass a parameter to avoid flushing the database on a specific call:
http://127.0.0.1:8000/drs/demoapp/scenario_1/?flush=0
Later you could see the results on the following url:
http://127.0.0.1:8000/demoapp/
It is possible to mock parts of your backend between scenarios calls. You need to add a new directory inside the scenarios directory and name ir 'mocks', then, again, add as many mocks as you want to implement and create a __init__.py so it becomes a module . Inside each of those files. You can apply as many mocks as you want and deactivate them selectibly. Pay special atention to the order this mocks are applied, as it may affect their internal behaviour.
To apply a mock just go to the following URL (assumming a file named mock_1 inside demoapp/mocks
http://127.0.0.1:8000/drs/demoapp/mocks/mock_1?activate=1
To remove the mock:
http://127.0.0.1:8000/drs/demoapp/mocks/mock_1?activate=0
An example of a mock can be found inside the test application
Experimental scenario and mocking browseable interface could be used to apply mocks and load scenarios by visting the root url for drs (on this case /drs/)
http://127.0.0.1:8000/drs/
