api-testing-jsonplaceholder

This project contains functional testing performed on a public REST API:

https://jsonplaceholder.typicode.com/posts

The goal was to validate expected and unexpected behaviors, analyze HTTP responses, and identify potential issues in data validation.

Testing Scope

• GET requests
• POST requests
• Positive and negative scenarios
• Response validation
• Error handling

Tools Used

• Postman
• REST API
• HTTP Protocol

Key Findings

| ID | Issue | Severity | Priority |

| API-POST-002 | Endpoint accepts invalid data without validation | HIGH | HIGH |

Learnings

During testing, I identified that some endpoints do not enforce input validation, which may lead to data integrity issues. This highlights the importance of backend validation even in simple APIs.
