In the world of web development, testing is an indispensable part of ensuring the reliability and robustness of our applications. When working with a modern framework like FastAPI, writing tests becomes a good practice and necessary to ensure that our APIs perform as expected. In this article, we will embark on a journey of testing in FastAPI, exploring various techniques and best practices along the way.

Introduction

FastAPI is a modern, fast (hence the name), web framework for building APIs with Python 3.7+ based on standard Python-type hints. Its asynchronous support and automatic interactive API documentation make it an excellent choice for developing web applications. However, no matter how advanced the framework, bugs can still creep into our code. That’s where testing comes in.

Setting Up the Project

Before we dive into testing, let’s set up our project structure. We have our main application files: main.py, models.py, schemas.py, and databases.py. Additionally, we have a separate file test_api.py dedicated to our test cases. This separation helps us maintain a clean and organized project structure.
