Expected Postconditions​

  • Marchosias: has -3 PWR and -2 DEF status (Pink Haze applied to her)

  • Duban: no status effects (untouched)

Assertions​

assert pwr_mod == -3, f"Marchosias should have -3 PWR status. Got {pwr_mod}"
    assert def_mod == -2, f"Marchosias should have -2 DEF status. Got {def_mod}"

    duban_def_mod = get_stat_modifier(result, duban_after, "def")
    assert duban_pwr_mod == 0, f"Duban should have 0 PWR status. Got {duban_pwr_mod}"
    assert duban_def_mod == 0, f"Duban should have 0 DEF status (ignoring passive). Got {duban_def_mod}"
