steps involved in test-driven development

As Django co-founder Jacob Kaplan-Moss says, “code without tests is broken as designed.” That’s why it’s essential to develop your applications with tests and success conditions in mind.

This course is an introduction to test-driven development and a practical guide on applying these principles to Django development. You’ll start with the purpose of automated testing, including the differences between test-driven development and development-driven testing. You’ll then be introduced to Django, a Python framework for building web applications. You’ll design and write a series of unit tests before building a complete web application using Django—a web application that will pass all the tests you designed, to ensure a robust, low-risk experience.

By the end of this course, you’ll be familiar with test-driven development, Red-Green Refactor methodology, and deploying quality applications using Django.

Build Robust Applications with Test-driven Development in Django

In this lesson, we write the simplest code that will make the test run successfully and also discuss refactoring. This means we combine the remaining three steps involved in TDD in this lesson.
