Testtests/test_abilities_complex.py::TestVapulaLocalEnemyApCostAura::test_local_enemy_has_plus_one_ap_cost

Vapula and an enemy share a lane — enemy gets +1 AP Cost.

Preconditions​

  • Lane 0: P1's Vapula (#100)

  • Lane 0: P2's Duban (#001, enemy of Vapula)

Action​

  • Query ap_cost passive modifier on Duban
from engine.abilities import get_passive_modifiers, clear_registries, FIELD_AURA_MODIFIERS
        # Fixture cleared registries + reloaded complex. Also reload passive so
        # Vapula's field aura is freshly registered exactly once.
        import importlib
        import engine.abilities_passive
        clear_registries()
        importlib.reload(engine.abilities_passive)
        # Re-register complex's registrations too (since clear wiped them)
        import engine.abilities_complex
        importlib.reload(engine.abilities_complex)

        vapula = make_demon("100", lane=0, owner=Side.PLAYER_1)
        duban = make_demon("001", lane=0, owner=Side.PLAYER_2)
        state, placed = _make_state_with_demons(vapula, duban)
        duban_p = placed[1]

        mod = get_passive_modifiers(state, duban_p, "basic_ap_cost")

Expected Postconditions​

  • Duban receives +1 ap_cost modifier from Vapula's field aura

Assertions​

assert mod == 1, (
            f"Local enemy Duban should have +1 basic_ap_cost from Vapula aura "
            f"(applies to Attack/March only, not custom abilities). Got {mod}."
        )
