Praise for

Test-Driven Development with Python

In this book, Harry takes us on an adventure of discovery with Python and testing.

It’s an excellent book, fun to read and full of vital information. It has my highest

recommendations for 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 testing practices.

—Michael Foord, Python Core Developer and Maintainer

of unittest

This book is far more than an introduction to test-driven development—it’s a complete

best-practices crash course, from start to finish, into modern web application

development with Python. Every web developer needs this book.

—Kenneth Reitz, Fellow at Python Software Foundation

Harry’s book is what we wish existed when we were learning Django. At a pace that’s

achievable and yet delightfully challenging, it provides excellent instruction for Django

and various test practices. The material on Selenium alone makes the book worth

purchasing, but there’s so much more!
