UX Coverage Metrics (Feature 24 - EDD Compliance) UX Coverage Metrics (Feature 24 - EDD Compliance)

Provides 100% provable UX coverage metrics for WASM games and TUI apps. Tracks which UI elements, interactions, and states have been tested.

EXTREME TDD: Tests written FIRST per spec

Probar Principles

• Error Prevention: Type-safe coverage tracking prevents blind spots
• Efficiency: Efficient hit counting without overhead
• User Journey Tracking: Coverage reflects actual user journeys
• Balanced Testing: Even distribution of test coverage

Simple Usage

use jugar_probar::gui_coverage;
use jugar_probar::ux_coverage::*;

// Define your GUI elements once
let mut tracker = gui_coverage! {
    buttons: ["start", "pause", "restart"],
    screens: ["title", "playing", "game_over"]
};

// Record interactions during tests
tracker.click("start");
tracker.visit("title");

// Get simple coverage report
println!("{}", tracker.summary()); // "GUI: 33% (2/6 elements)"
