+# Test Plan for Swagger Petstore API
+
+## Introduction
+This document describes the test plan for automated testing of the PetStore API. The goal of testing is to verify
+the correctness of the main endpoints and their compliance with the documentation.
+The tests will be implemented using Playwright.
+
+## Test Approach
+The testing approach for the PetStore API focuses on verifying that the API aligns with its documented specifications and consistently performs as expected under different conditions.
+
+## Test Types
+Functional Testing: Verify that each API endpoint works as expected, including correct CRUD operations (Create, Read, Update, Delete). 
+Boundary Testing: Test edge cases to ensure the API handles inputs at the extremes (e.g., large data sets, maximum and minimum field values).
+Error Handling: Test both positive and negative scenarios, in case the server is designed to handle negative scenarios.
+
+## Risk & Mitigation
+- **API Instability**
+**Risk**: The Pet Store API may experience downtime or unexpected behavior during testing, leading to test failures or delays.
+**Mitigation**: Monitor the API's status and schedule tests during off-peak hours.
+
+- **Incomplete Test Data**
+**Risk**: Insufficient test data may result in incomplete test coverage. Without proper data, some scenarios, especially edge cases, may be missed.
+**Mitigation**: Develop a well-rounded dataset that includes both positive and negative test cases. This should cover normal use cases and edge conditions.
+
