# Task Assignment — Test Writer Milestone 3 (TileMapRenderer & 30 Biomes Procgen E2E)

Scope:
Develop automated test suites:
1. `tests/unit/test_biome_texture_manager.js` (Node.js test):
   - Test BiomeTextureManager pattern caching, fallback retrieval, active biome switching, memory footprint.
2. `tests/e2e/test_30_biomes_generation_e2e.py`:
   - Test that `WildernessMapGenerator` can generate valid maps for all 30 biomes (seeds 1..30).
   - Test that `serialize_map_grid()` packs all 30 biome codes accurately into the 16-byte binary header.
   - Test that client `TileGridLoader.loadBinaryMap` correctly parses all 30 biome codes from binary payloads.
   - Test that `tools/serve_webapp.py` `/api/map` endpoint returns valid binary maps with the requested biome code.
