//-->Praise forTest-Driven Development with Python“In this book, Harry takes us on an adventure of discovery with Python and testing. It’s anexcellent book, fun to read and full of vital information. It has my highest recommendationsfor anyone interested in testing with Python, learning Django or wanting to use Selenium.Testing is essential for developer sanity and it’s a notoriously difficult field, full of trade-offs. Harry does a fantastic job of holding our attention whilst exploring real world testingpractices.”— Michael FoordPython Core Developer and Maintainer of unittest“This book is far more than an introduction to Test Driven Development—it’s a completebest-practices crash course, from start to finish, into modern web application developmentwith Python. Every web developer needs this book.”— Kenneth ReitzFellow at Python Software Foundation“Harry’s book is what we wish existed when we were learning Django. At a pace that’sachievable and yet delightfully challenging, it provides excellent instruction for Django andvarious test practices. The material on Selenium alone makes the book worth purchasing,but there’s so much more!”— Daniel and Audrey Roy Greenfieldauthors ofTwo Scoops of Django(Two Scoops Press)Test-Driven Development withPythonHarry PercivalTest-Driven Development with Pythonby Harry PercivalCopyright © 2014 Harry Percival.
