Testtests/test_abilities_familiars.py::test_question_challenge_with_lie_no_damage_to_allies

A demon Challenges a Question familiar that has Lie underneath.

Preconditions​

  • Lane 1: P1's Question (120_3) with hidden_card="120_2" (Lie).

  • Lane 1: P2's Duban (001) — READIED (will be the challenger).

  • No other demons in lane 1.

  • P1's familiar_deck = [] (Question and Lie are in play).

Action​

  • Execute Challenge ability (action[1] of Question, 120_3) with Duban as performer,
from engine.abilities import execute_ability

    state = make_game_state()
    state.players[Side.PLAYER_1].cp = 0
    state.players[Side.PLAYER_2].cp = 0
    state.players[Side.PLAYER_1].familiar_deck = []
    state.players[Side.PLAYER_2].familiar_deck = []

    # Place Question with Lie hidden underneath
    question = make_familiar_demon("120_3", lane=1, owner=Side.PLAYER_1,
                                   current_hp=1)  # null hp → use 1 for testing
    question.abilities_used_this_turn = {"hidden_card": "120_2"}  # Lie underneath
    state = place_demon(state, question)
    question = state.demons[-1]

    # Place Duban (challenger) in the same lane
    duban = make_demon("001", lane=1, owner=Side.PLAYER_2)
    state = place_demon(state, duban)
    duban = state.demons[-1]

    # Execute Challenge: Duban challenges the Question
    from engine.abilities_familiars import _question_challenge_handler
    new_state = _question_challenge_handler(state, duban, [question], {}, None)

    # Question removed from field
    question_on_field = [d for d in new_state.demons if d.unit_id == "120_3"]

Expected Postconditions​

  • Question is removed from field (not added to any pile — not dead).

  • No damage dealt to Duban or its allies (Lie doesn't trigger damage).

  • P1 CP = 0 (Question and Lie are not considered dead).

  • P2 CP = 0.

Assertions​

assert len(question_on_field) == 0, (
        "Question should be removed from field after Challenge resolves."
    )

    # No damage to Duban (Lie → no ally damage)
    duban_after = next((d for d in new_state.demons if d.unit_id == "001"), None)
    assert duban_after is not None, "Duban should still be on field."
    assert duban_after.damage == 0, (
        f"Duban's allies take no damage when Lie is revealed. "
        f"Got damage={duban_after.damage}."
    )

    # No CP change (Question/Lie are not dead)
    assert new_state.players[Side.PLAYER_1].cp == 0, (
        "P1 should NOT gain CP when Question is revealed — it's not considered dead."
    )
    assert new_state.players[Side.PLAYER_2].cp == 0, "P2 CP should be 0."
