[WIP] An approach towards test driven development in Python.

py-tdd

A very minimal application made on Django, in order to deliver a heavily tested and automatically deployed To-Do lists webapp.

"Always obey the Testing Goat."

Get it running locally

git clone https://github.com/adityaprakash-bobby/py-tdd
cd py-tdd/

# setup a virtual environment
python3 -m venv virtualenv

# prep the dev server
./virtualenv/bin/pip install -r requirements.txt

# start the dev server
./virtualenv/bin/python manage.py runserver

# run tests
#   e2e test:
./virtualenv/bin/python manage.py test functional_tests
#   unit tests:
./virtualenv/bin/python manage.py test lists

Get it running in the web

I am using an EC2 machine as my deployment server inorder to get my site published. Got a free domain registered at freenom.com. And using a nginx + gunicorn setup for the deployment of the staging and live server. I will be uploading the deployment settings soon.

you can follow the guide in deploy_tools

Using fabric CLI

This will be very specific to deployment to AWS EC2 servers. We assume that you already have the private_key file used to log in to your remote machine. It will be used the same way you use it for logging into EC2 instances. You have to provides the username and host address of the instance.

cd /path/to/your/local/git/repo/

source virtualenv/bin/activate

cd deploy_tools/

fab -i /path/to/private_key.pem deploy:host=username@host_address

py-tdd's Issues

functional_tests.test_layout_and_styling behaving abnormally

The functional test to make sure the input textbox in the pages is center-aligned, is behaving in a very erratic manner. The selenium browser window is resizing to the size I want but, it does pass sometimes and fails the rest of the time.

This problem seemed to occur when I switched from i3environment to gnome environment.

       [...]
       def test_layout_and_styling(self):
              # User goes to the home page
              self.browser.get(self.live_server_url)
              self.browser.set_window_size(1024, 768)

              # He/she notices the input box is nicely centered
              inputbox = self.get_item_input_box()
              self.assertAlmostEqual(
                      inputbox.location['x'] + inputbox.size['width'] / 2,
                      512,
                      delta=10
              )
       [...]

It fails after this.

Setup Jenkins server to automate tests

Prepare another EC2 machine for setting up Jenkins server with GUI and automate the functional tests as well as unit tests

Complete the logic of saving new user-lists
