7. Testing Update in our Elixir REST API Project

In this step-by-step tutorial, we're progressing further, shifting our focus to the next crucial function in our 'accounts.ex' context file - the 'update' function. As discussed, this file is the nucleus for our fundamental CRUD operations - create, read, update, and delete.

In our preceding videos, we've constructed and employed a factory to produce the data required for our tests, a practice we will uphold in today's video. It's important to remember that we always need two forms of data when interacting with database tables - valid and invalid.

As our applications expand, preserving a unified setup data source becomes increasingly vital. This practice streamlines our testing process, and when we need to adjust a schema definition, this single source typically remains the only aspect requiring alteration.

Expanding on our accumulated knowledge, we'll utilize our established factory and the ExMachina library. ExMachina is an exceptional asset that simplifies the generation of test data and associations and melds flawlessly with Ecto.

So, let's dive in and discover how to efficiently test the 'update' function in our context file!
