In this step-by-step tutorial, we'll test our Ecto Schema constraints using database interactions. We will learn how constraints work with databases in our Elixir REST API project. We'll demonstrate how to interact with a database for Ecto Schema tests and how Ecto uses constraints to return database errors in our changeset. We'll also explore setting up Ecto Sandbox for our tests, ensuring a clean and controlled testing environment.
Subscribe now, and we'll walk through a hands-on introduction to Phoenix and Elixir. If you want to learn how to code in Elixir, this Elixir tutorial is the perfect introduction! I will teach you the basics of setting up a RESTful API and programming concepts, so you can start building powerful applications in this beautiful language.
