Ensuring Elixir Application Performance with Testing and ExUnit
Gain insights into unit testing Elixir applications with ExUnit, explore advanced integration and E2E testing, and master OTP, Phoenix frameworks, API testing, and platform-specific refactoring.
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.
