Phoenix Web Development

By: Brandon Richey

Overview of this book

Phoenix is a modern web development framework that is used to build API’s and web applications. It is built on Elixir and runs on Erlang VM which makes it much faster than other options. With Elixir and Phoenix, you build your application the right way, ready to scale and ready for the increasing demands of real-time web applications. This book covers the basics of the Phoenix web framework, showing you how to build a community voting application, and is divided into three parts. In the first part, you will be introduced to Phoenix and Elixir and understand the core terminologies that are used to describe them. You will also learn to build controller pages, store and retrieve data, add users to your app pages and protect your database. In the second section you will be able to reinforce your knowledge of architecting real time applications in phoenix and not only debug these applications but also diagnose issues in them. In the third and final section you will have the complete understanding of deploying and running the phoenix application and should be comfortable to make your first application release By the end of this book, you'll have a strong grasp of all of the core fundamentals of the Phoenix framework, and will have built a full production-ready web application from scratch.

Writing controller tests

We'll want to have some good tests covering all of the code that we will be writing in the course of this application, since we're all good software engineers and should follow good software engineering processes! We'll start off with our controller tests, which include a few cool tools to simulate making connection requests to various controller actions and inspecting the output of the controller functions.

Understanding the code behind tests

When we start off creating our own controllers/views/etc, if we're not using a generator, we won't have any new logic or functionality to cover tests for the new code we’re writing. Due to this, if we just run mix test without...
