Analyze a single target project to identify data access artifacts that require integration testing, then produce a structured, actionable testing plan.

Comprehensive guidance for unit, widget, and integration testing across Flutter applications. \n \n Covers three test types with trade-off analysis: unit tests for isolated logic (fast, low maintenance), widget tests for UI components (higher confidence, more dependencies), and integration tests for end-to-end flows (highest confidence, slowest execution) \n Includes practical examples for all three test categories, from basic Counter tests to complex user flows and performance profiling \n Prov
