Unit Testing with Pytest
Write effective unit tests for your FastAPI functions and modules using the Pytest framework.
What is Unit Testing?
Welcome to unit testing! This is a fundamental practice in software development that helps ensure your code works correctly.
- Unit testing focuses on testing the smallest testable parts of an application, called 'units'.
- A 'unit' can be a function, a method, or a class. The goal is to isolate it and verify it behaves as expected.
- This helps catch bugs early, makes code easier to refactor, and builds confidence in your application's reliability.
Introducing Pytest
For Python, one of the most popular and powerful testing frameworks is Pytest. It's known for its simplicity and flexibility.
- Pytest makes it easy to write simple, yet scalable tests.
- It automatically discovers tests, provides detailed failure reports, and supports advanced features like fixtures.
- You'll find Pytest widely used in the Python community, including for FastAPI projects.
