#README.md

This is a summary document as I work through Test Driven Development with Python and hopefully learn Django in the process.

I'll include things like notes, sections, code snippets, and code I've worked through / modified in order to get things up and running.

• Use the unittest framework instead of simply writing functions

• The def setUp and def tearDown are special functions inside of class uittest.TestCase to set up the function

Functional Tests: test the application from the outside, from the point of view of the user.

Unit tests: test the application from the inside, from the point of view of the programmer.

NOTE: Functional tests should help you build an application with the right functionality, and guarantee you never accidentally break it. Unit tests should help you to write code that’s clean and bug free.

It's incredibly easy to create a Django app (that lives inside of a project) using the $python manage.py startapp <app_name> syntax

Create an app within the superlists project called lists.

$python manage.py startapp lists

Now the doc-tree looks like:

Running the Django dev server

$python manage.py runserver

Running the functional tests

$python functional_tests.py

Running the unit tests

$python manage.py test

The unit-test/code cycle

1. Run the unit tests in the terminal.
2. Make a minimal code change in the editor.
3. Repeat
