Test Data Strategy

Design a test data strategy for testing this feature.

FEATURE: [Description]
DATA REQUIREMENTS:
- [Entity 1]: [What states/variations are needed]
- [Entity 2]: [What states/variations are needed]

ENVIRONMENTS:
- [Dev / Staging / Pre-prod]
- Database: [Type]
- API mocking: [Available? Tool?]

Generate:
1. Test data scenarios needed (one per meaningful variation)
2. For each scenario: the specific data values and why they matter
3. Test account requirements (roles, permissions, states)
4. Edge case data (empty, null, max length, special characters, unicode)
5. How to create/reset this data (API calls, scripts, manual setup)
6. Data isolation strategy (how to avoid test interference)
