CategoryAbility
StatusPassing
Testtests/test_operations.py::test_get_effective_ap_cost_basic_vs_custom_action

Tests interaction between Forneus.

Preconditions​

  • Lane 0: P1's Forneus (#097) — READIED

  • Forneus has passive idx=2: +1 AP Cost on basic actions

  • ACTION 1: Query get_effective_ap_cost(state, forneus, 2, is_basic_action=True)

  • ACTION 2: Query get_effective_ap_cost(state, forneus, 2, is_basic_action=False)

Action​

See code below.

# Earlier tests in the suite (e.g. TestVapula) call clear_registries();
    # reload abilities_passive to ensure Forneus's passive is registered.
    import importlib
    import engine.abilities_passive
    from engine.abilities import clear_registries
    clear_registries()
    importlib.reload(engine.abilities_passive)

    from engine.operations import get_effective_ap_cost
    state = make_game_state()
    forneus = make_demon("097", lane=0, owner=Side.PLAYER_1)
    state = place_demon(state, forneus)
    placed = state.demons[0]

    basic_cost = get_effective_ap_cost(state, placed, 2, is_basic_action=True)
    custom_cost = get_effective_ap_cost(state, placed, 2, is_basic_action=False)

Expected Postconditions​

  • Basic call: 3 (2 base + 1 from Forneus basic_ap_cost passive)

  • Custom call: 2 (2 base — Forneus's passive does not apply to custom abilities)

Assertions​

assert basic_cost == 3, (
        f"Forneus's +1 AP Cost applies to basic actions. Got {basic_cost}."
    )
    assert custom_cost == 2, (
        f"Forneus's basic_ap_cost must NOT apply to custom abilities. Got {custom_cost}."
    )
