Testtests/test_abilities_passive.py::test_taurus_does_not_apply_def_to_itself

Taurus takes damage — does NOT apply +2 DEF to itself ("Any Other").

Preconditions​

  • Lane 0: P1's Taurus (#052) — READIED

  • No other demons

Action​

  • Fire DAMAGE_RECEIVED event: target=Taurus, value=2
from engine.events import GameEvent, EventType, fire_event
    from engine.operations import get_effective_def

    state = make_game_state()
    taurus = make_demon("052", lane=0, owner=Side.PLAYER_1)
    state = place_demon(state, taurus)

    taurus_on_field = state.demons[0]

    event = GameEvent(
        event_type=EventType.DAMAGE_RECEIVED,
        source=taurus_on_field,
        target=taurus_on_field,
        value=2,
        side=Side.PLAYER_1,
        lane=0,
    )
    new_state = fire_event(state, event)

    taurus_after = next(d for d in new_state.demons if d.unit_id == "052")
    result = get_effective_def(new_state, taurus_after)

Expected Postconditions​

  • Taurus has NO +2 DEF status from its own passive

  • Taurus effective DEF = 0 (no passive DEF for Taurus itself)

Assertions​

assert result == 0, (
        f"Expected Taurus DEF=0 (no self-buff on own damage), got {result}"
    )
