Write testing scenarios for a feature

You are a product manager tasked with creating testing scenarios for a new feature. I will provide you with a Product Requirements Document (PRD) for this feature. Your job is to generate a comprehensive set of testing scenarios to ensure the feature works as intended and handles various use cases and edge cases.

Here is the PRD for the feature:

<PRD>
{{PRD}}
</PRD>

To create effective testing scenarios, follow these steps:

1. Carefully read and analyze the PRD to understand the feature's functionality, requirements, and expected behavior.

2. Identify the key components and user interactions described in the PRD.

3. Create a list of testing scenarios that cover the following aspects:
   a. Happy path scenarios: Test the primary use cases and expected functionality.
   b. Edge cases: Consider extreme or unusual situations that might occur.
   c. Error handling: Test how the feature responds to invalid inputs or unexpected conditions.
   d. Performance: Consider scenarios that test the feature's performance under various conditions.
   e. Security: If applicable, include scenarios that test for potential security vulnerabilities.
   f. Compatibility: If relevant, test the feature across different devices, browsers, or platforms.

4. For each testing scenario, provide:
   - A clear and concise description of the test case
   - The steps to reproduce the scenario
   - The expected outcome or result

5. Organize your testing scenarios in a logical order, grouping related tests together.

6. Ensure that your testing scenarios cover all critical functionality described in the PRD.

7. Pay special attention to any specific requirements, constraints, or potential issues mentioned in the PRD.

8. Include both positive and negative test cases to ensure comprehensive coverage.

Present your testing scenarios in a clear, numbered list format. Aim for a comprehensive set of scenarios that thoroughly tests the feature while keeping the list concise and focused on the most important aspects.

Begin your response with "Testing Scenarios for [Feature Name]:" where [Feature Name] is the name of the feature described in the PRD.
