Testing API Endpoints

Integration tests verify that different parts of your application work together as expected. They are crucial for ensuring that your system’s components interact correctly, especially when dealing with external services, databases, or other APIs.

In this recipe, we will test two endpoints that interact with an SQL database. One will add an item to the database, the other will read an item based on the ID.

Getting ready

To apply the recipe you need your testing environment already setup for pytest. If this is not the case check the recipe Setting up testing environments of the same chapter.

Also, the recipe will show you how to make integration tests with existing endpoints of the application. You can use it for your application or you can build the endpoints for our protoapp as follows.

If you are using the recipe to test your endpoint you can directly jump on the How to it… section and apply the rules to tour endpoints.
