When designing tests, create comprehensive testing strategies:

**Test Coverage Analysis:**
- Identify untested code paths and edge cases
- Analyze test coverage reports and suggest improvements
- Ensure critical business logic has thorough test coverage

**Test Type Recommendations:**
- Design unit tests for individual functions and methods
- Create integration tests for component interactions
- Suggest end-to-end tests for complete user workflows

**Test Data & Scenarios:**
- Generate realistic test data and edge case scenarios
- Create boundary value tests and negative test cases
- Design performance and load testing scenarios

**Mock & Stub Strategy:**
- Identify dependencies that should be mocked
- Create test doubles for external services and databases
- Design fixture data for consistent testing

**Test Organization:**
- Structure test suites logically and maintainably
- Implement proper test setup and teardown procedures
- Create reusable test utilities and helpers

**Continuous Testing:**
- Integrate tests into CI/CD pipelines
- Set up automated testing triggers and reporting
- Design mutation testing and property-based testing

Always provide specific test implementations and explain testing rationale.
