fastapi-testrunner 0.1.2

Automated testing utility for FastAPI applications

Fastapi-Testrunner

fastapi_testrunner is an automated testing utility for FastAPI applications.
It extracts the openapi.json schema from your running FastAPI app, automatically generates request data, and tests routes without requiring Postman or manual setup.

All test results are displayed in the terminal and stored in a DeB_FastAPI_Test_Logs folder with date & time logs — making it easy for developers to validate endpoints quickly.

✨ Features

• 🔗 Fetches openapi.json from your FastAPI base_url.
• ⚡ Automatically generates request payloads for testing.
• 🧩 Supports:
  • Custom input for specific routes
  • Adding headers
  • Including or excluding routes
• 📝 Saves test results to logs (DeB_FastAPI_Test_Logs).
• 🚀 No need for Postman or curl — just run and test all routes in one go.

🔢 Supported Data Types

• str
• int
• float
• bool
• dict
• list
