Testing is an essential part of the software development life cycle. A good automated testing suite streamlines feedback, allowing rapid creation and tight control over specific application components.

This course is a comprehensive introduction to testing Elixir applications with ExUnit. You’ll start with a review of unit testing principles before diving into writing tests with the ExUnit. You’ll build a comprehensive suite of unit tests before moving on to more advanced testing, including integration, end-to-end, and property-baste testing. In addition to the core Elixir environment, you’ll also develop tests for OTP, the Phoenix web framework, including JSON APIs and Ecto schematics. You’ll also explore refactoring for different platforms, server rendering, and design strategies.

By the end of this course, you’ll be an expert in unit testing Elixir applications with ExUnit and ready to build robust, performant applications using Phoenix.

Ensuring Elixir Application Performance with Testing and ExUnit

Dependency doubles are a great tool for testing, but their benefits extend to the design of our applications as well. 






If we look back at the changes we made to be able to use a double for the weather API interface, there were two key points:
* Making the interface swappable at the call site (in `rain?/2`)
* Defining a behavior for the interface

Both of these things end up making our application less tightly coupled and better structured. Now, we have a clear point of separation between our system and the external system.

Learn about the benefits we achieved by using dependency doubles in our SoggyWaffle application.
