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

# What is an integration test?
**Integration tests** are those tests that cover the integration of different components (be they external systems or various parts of an application).

Integration tests are fundamental to testing a system. Unit tests give us confidence that our functions and modules behave correctly, but we need to test that our system functions correctly as a whole, and to do that, we need to test the glue between the components of the system. This is where integration tests come in.
 

# Example

Let’s start by looking at an example of integration testing.

A common scenario is an HTTP-based web application with a router that routes requests to different functions based on the request URI. Those functions are usually contained in modules called **controllers**. A controller function is responsible for doing any necessary manipulation on the request data, formulating an output, and sending a response back to the client.

The code for the router and the controller could look something like this:
