Are your API tests brittle, hard to reproduce, or impossible to onboard new team members onto? In this video, you’ll learn a professional REST Assured Playbook you can clone, run, and adapt in 2 minutes.

This REST Assured tutorial walks through a fully runnable API automation framework, not just snippets.


🚀 Live Demo: REST Assured Playbook
Quick walkthrough of the GitHub repository
README.md with clone → build → run instructions
Maven project with clean structure

The repo includes:
`BaseTest` – centralized configuration
`PetApiTest` – real API test cases
JSON payload templates for dynamic test data

🧪 Demo Test Cases

1️⃣ Get Pet by ID
Action
Generate random pet ID
POST `/pet` to create a pet
GET `/pet/{id}` using same ID
Assertions
HTTP 200 OK for POST & GET
Verify `id`, `name`, `status`

2️⃣ Create Pet and Verify
Action
Generate unique pet ID
Read `pet_create.json`
Replace placeholders dynamically

3️⃣ Negative Case (404)
Action
DELETE `/pet/{id}` to ensure absence
GET `/pet/{id}` and verify 404

▶️ Running the Suite
Execute `.\run_demo.bat`
Command: `mvn clean test`
Output:

BUILD SUCCESS
Tests run: 3
Failures: 0

Logs show full request, response, and assertions.
