TUI Testing Best Practices

Comprehensive testing strategies for Bubbletea v2 applications, based on the hive diff viewer implementation.

Testing Strategy Overview

Use a layered approach with different test types for different concerns:

Unit Tests          → Pure logic, state transformations
Component Tests     → Update/View behavior with synthetic messages
Golden File Tests   → Visual regression testing of rendered output
Integration Tests   → End-to-end workflows with teatest
