Introdução a testes com Django (2013)
1 like•539 views
This document introduces testing in Django, including why testing is important, how to write unit and functional tests, best practices for test organization and structure, using fixtures and factories to generate test data, and higher level testing tools like Selenium and Splinter that can be used for browser-based acceptance testing. It covers Django's built-in test framework and recommends using pytest and factory boy/model mommy for test data generation. The goal is to establish a testing culture where tests are modular, well-written, and easy to understand.
