Hi there, I work for a bunch of XP fanatics, so we do quite religious TDD in our Python/Django development. We start with functional/acceptance tests, which we write using Selenium, driving a real web browser, and following a test script that is essential a user story. We then write unit tests that we can run using a python manage.py test.
I've written a "TDD for beginners" tutorial, that covers both of these types of test: http://www.tdd-django-tutorial.com/ I'd love any comments, feedback, suggestions? rgds, Harry On Thursday, September 6, 2012 1:47:08 AM UTC+1, Mike Dewhirst wrote: > > On 6/09/2012 3:04am, Javier Guerra Giraldez wrote: > > On Wed, Sep 5, 2012 at 7:46 AM, jyria <jyr...@gmail.com <javascript:>> > wrote: > >> What is your experience?
