Writing tests for REST API endpoints
With everything in place, let’s create the test_login.py file, where we’ll test the authentication routes:
(venv)$ touch tests/test_login.py
In the test file, we’ll start by importing the dependencies:
import httpx import pytest
Testing the sign-up route
The first endpoint we’ll be testing is the sign-up endpoint. We’ll be adding the pytest.mark.asyncio decorator, which informs pytest to treat this as an async test. Let’s define the function and the request payload:
@pytest.mark.asyncio
