Development with Python

APPENDIX F

Cheat Sheet

By popular demand, this “cheat sheet” is loosely based on the little recap/summary boxes

from the end of each chapter. The idea is to provide a few reminders, and links to the

chapters where you can find out more to jog your memory. I hope you find it useful!

Initial Project Setup

• Start with a

User Story

and map it to a first

functional test

• Pick a test framework—

unittest

is fine, options like

py.test

and

nose

can also

offer some advantages.

• Run the functional test and see your first

expected failure

• Pick a web framework such as Django, and find out how to run

unit tests

against it.

• Create your first

unit test

to address the current FT failure, and see it fail.

• Do your

first commit

to a VCS like

Git
