Postman API Testing Project

This project demonstrates my skills in API testing using Postman. I tested the ReqRes API, a free dummy API, to perform various operations like GET, POST, PUT, DELETE, and validated responses using Postman tests. I also used Postman Environments, Newman for command-line execution, and htmlextra for generating detailed HTML reports.

Tools and Technologies Used

• Postman: For API testing and automation.
• Newman: For running Postman collections from the command line.
• htmlextra: For generating detailed HTML reports.
• ReqRes API: A free dummy API for testing CRUD operations.

Features

1. API Testing:

   • Tested GET, POST, PUT, DELETE endpoints.
   • Validated status codes, response time, and response data types.
   • Used Postman tests to ensure API responses are correct.

2. Environment Variables:

   • Used Postman Environments to manage variables like url.

3. Reports:

   • Generated HTML reports using htmlextra for better visualization of test results.

4. Test Cases:

   • Validated response time (e.g., response time < 500ms).
   • Checked status codes (e.g., 200 for success, 201 for created, 204 for deleted).
   • Verified response data types (e.g., name is a string, id is a number).

How to Set Up and Run the Project

1. Clone the Repository

git clone https://github.com/daniyalfarman/Postman-API-Testing-Demo.git
cd postman-api-testing-demo

2. Install Dependencies

Install Newman and htmlextra globally:

npm install -g newman newman-reporter-htmlextra

3. Run the Collection

Run the Postman collection using Newman:

newman run postman_api_testing_demo.json -e postman_api_testing_env.json

4. Create HTML Report

Run the Postman collection using Newman:

newman run postman_api_testing_demo.json -e postman_api_testing_env.json -r htmlextra

5. View the Report

After running the tests, an HTML report will be generated in the newman folder. Open it in your browser:

open newman/ `nameofhtmlfile`
