🔬 Hands-on API Testing project using Postman based on Simple Books API. Covers real-world scenarios like registration, listing, ordering, and validation.

🧪 API Testing Project – Simple Books API

This is a hands-on API testing project built using Postman, based on the public Simple Books API.
The goal is to simulate real-world scenarios such as user registration, listing books, placing orders, and testing API responses using assertions.

📁 Project Contents

✅ Test Cases for:
- API Status Check
- User Registration
- Listing Books (with filters)
- Get Single Book by ID
- Place Book Orders
- Get, Update, and Delete Orders
🧪 Postman test scripts
🌐 Usage of environment variables (baseURL, accessToken, bookID, orderID)
📋 Test result assertions (status codes, response body validation)

🧰 Tools Used

Postman
JavaScript Test Scripts (for response validation)
Environment Variables
(Optional) Excel / Markdown for reporting

📌 How to Use

Clone or download this repository.
Import the API Course.postman_collection.json into Postman.
Set the baseURL to: https://simple-books-api.glitch.me
Register a client to get accessToken.
Set environment variable accessToken to access protected endpoints.
Run requests step-by-step or in sequence.
