Test Plan - Voxel Cutaway World Generator

Version: 0.2.0
Date: 2026-03-08
Author: Rens Roosloot / Codex collaboration

1. Purpose

This document defines the prototype test approach for the Voxel Cutaway World Generator MVP.

2. Test Objectives

• verify that the core concept is understandable on first load
• verify that generation remains deterministic by seed
• verify that desktop and mobile interaction both work
• verify that day/night theme switching remains readable
• verify that the page remains responsive on target devices

3. Test Scope

In scope:

• standalone page load
• initial chunk rendering
• regeneration behavior
• deterministic seed behavior
• camera orbit/zoom behavior
• touch interaction behavior
• basic visual coherence of generated worlds

Out of scope during this prototype phase:

• exhaustive cross-browser certification
• long-session soak testing
• persistence testing
• multiplayer or backend testing

4. Verification Approach

4.1 Manual exploratory checks

• confirm the cutaway concept is obvious at first view
• confirm the default camera angle is strong
• confirm rotate and zoom behavior feel natural
• confirm regenerate produces variety without obvious breakage
• confirm day/night both remain readable

4.2 Deterministic checks

• same seed produces same world output
• different seeds produce meaningfully different output

4.3 Responsive checks

• verify controls remain usable on small mobile screens
• verify touch targets are large enough
• verify pinch zoom is functional and bounded

4.4 Performance smoke checks

• verify smooth interaction on a typical desktop browser
• verify acceptable interaction on a typical modern phone
• verify regeneration time remains near-instant at MVP chunk size

5. Suggested Test Cases

• TP-01: Page loads and renders one floating voxel chunk without console errors.
• TP-02: Regenerate updates the chunk without page reload.
• TP-03: Re-entering the same seed reproduces the same output.
• TP-04: Desktop pointer drag rotates the chunk.
• TP-05: Desktop scroll wheel zooms within allowed bounds.
• TP-06: Mobile touch drag rotates the chunk.
• TP-07: Mobile pinch zoom works within allowed bounds.
• TP-08: Day theme remains readable.
• TP-09: Night theme remains readable.
• TP-10: Generated chunks show visible underground composition on the cut faces.

6. Exit Criteria for MVP

The MVP is ready for implementation review when:

• the documentation set is internally consistent
• the MVP scope is clearly bounded
• the accepted controls and world rules are stable enough to build
• the main risks and test priorities are documented
