Test SignUp & SignIn APIs in FastAPI | Authentication Flow Verified

Описание: Welcome to another video of the FastAPI Series! 🌙

In this session, we’re testing the SignUp and SignIn APIs to ensure our authentication flow works correctly end‑to‑end. ✅🔐

After building Signup and Login APIs, testing them properly is critical — this video walks through valid, invalid, and edge‑case scenarios to confirm everything behaves as expected.

By the end of this lesson, you’ll understand:
✅ How to test the SignUp API in FastAPI
✅ How to test the SignIn (Login) API
✅ How to verify password hashing and validation
✅ How to handle and test error cases (wrong password, duplicate email, user not found)
✅ How to validate correct HTTP status codes
✅ How to use Swagger UI / API client for testing
✅ Why testing authentication APIs is critical before production

With hands‑on testing, clear explanations, and real API responses, you’ll gain confidence that your authentication system is secure, reliable, and production‑ready. 🚀
