What problem does it solve?

This Skill addresses the dilemma of refactoring legacy code by creating characterization tests that capture its current, often undocumented, behavior, providing a safety net for changes.

Core Features & Use Cases

  • Automated Test Generation: Creates characterization tests for ViewModels, Repositories, Services, and Widgets.
  • Behavioral Snapshotting: Captures existing code behavior using ApprovalTests or Golden Tests.
  • Refactoring Safety Net: Enables confident refactoring by ensuring current behavior is preserved or intentionally changed.
  • Use Case: Before refactoring a complex authentication module, use this Skill to generate tests that document its current sign-in, sign-up, and error handling behaviors.

Quick Start

Use the characterization-testing skill to create tests for the AuthViewModel class.
