|
* Standalone Adversarial Stress-Test Script for Milestone M3
|
|
* Diablo II Web DRLG Engine: Dynamic Barricade Extent & Reachability (Phase D4a)
|
|
*
|
|
* Requirements:
|
|
* 1. Test edge cases on resolveUnsetSize:
|
|
* - Empty pieces array -> assert UnresolvedLevelSizeError is thrown.
|
|
* - Non-barricade level without pieces -> assert UnresolvedLevelSizeError is thrown.
|
|
* - Non-barricade level with non-barricade pieces -> assert UnresolvedLevelSizeError is thrown.
|
|
* - Combinations of entrance/exit piece counts & dimensions (1,000 randomized configurations):
|
|
* verify sizeY > sizeX always holds, sizeX in [48..64], sizeY in [160..192].
|
|
* 2. Run generation of Level 111 and Level 112 across 50 distinct seeds:
|
|
* - Verify sizeX in [48..64] and sizeY in [160..192] for 100% of seeds.
|
|
* - Verify sizeY > sizeX holds for 100% of seeds.
|
|
* - Verify 100% flood-fill reachability from player spawn for 100% of generated layouts.
|
|
* - Verify choke-point gates in palisade walls are traversable:
|
|
* - Gate openings are clear of walls and have walkable floor.
|
|
* - Sub-tile collision in gate openings is unblocked (blocked === 0).
|
|
* - Local gate traversability (South to North through gate) holds.
|
|
* - Global corridor traversability (South entrance to North exit) holds.
|
|
* 3. Report total assertions and failure count with explicit APPROVE or REJECT verdict.
|
|
*
|
|
* Archetype: EMPIRICAL CHALLENGER
|
|
* Run: npx tsx scripts/stress-barricade-extent.ts [mpq_directory]
