🧪 PetStore API Testing with Postman, Newman & Jenkins CI/CD

🚀 Overview - This project demonstrates end-to-end API automation testing using Postman, Newman, and Jenkins CI/CD integration. It covers automated testing of the Swagger PetStore API, including test creation, validation, report generation, and continuous integration setup.

🧰 Tech Stack -

1.Postman – for designing and running API requests 2.Newman – Postman’s command-line tool for automation 3.HTML Extra Reporter – for generating detailed HTML reports 4.Jenkins – for CI/CD pipeline execution 5.Git & GitHub – for version control and repository management

🧩 Features Implemented

✅ Created a Postman collection for: a.Creating, retrieving, updating, and deleting pets in the Swagger PetStore b.Dynamic environment variable handling c.Retry mechanism for 404 responses (auto re-execution logic) ✅ Exported the Postman collection and environment for Newman execution ✅ Automated execution using Newman CLI ✅ Added delay handling and retry logic for real-world API sync issues ✅ Generated beautiful HTML Extra Reports ✅ Integrated with Jenkins for automated test runs ✅ Published the test report directly in Jenkins UI ✅ Linked the complete project with GitHub for version control

🔄 Jenkins Job Flow

1.Jenkins fetches the latest project files 2.Executes Newman command: newman run PetStore_API_Testing.postman_collection.json -e PetStore.postman_environment.json -r htmlextra --reporter-htmlextra-export report.html 3.Waits between requests to ensure API stability 4.Publishes HTML Extra report under “HTML Report” tab in Jenkins 5.Implemented smart retry logic in Request Pet to handle 404s gracefully

📊 Reports

1.The project generates: 2.Newman HTML Extra Report → report.html 3.Stored and viewable via Jenkins HTML Publisher plugin

🧠 Learning Outcomes

Through this project: 1.Understood end-to-end API automation workflow 2.Gained hands-on experience with CI/CD integration for testing 3.Learned Git & GitHub version control fundamentals 4.Built reusable and maintainable Postman collections

🌐 Future Enhancements

1.Add CI pipeline with GitHub webhooks 2.Integrate Slack/Email notifications for test runs 3.Migrate collections into a Docker container for scalable runs
