Для необязательных полей вы можете использовать оператор Элвиса ?:
следующим образом (извините, длинный код, я смоделировал вашу базу данных и два новых тестовых примера, один со многими дополнительными полями и один неудачный тест):
package de.scrum_master.stackoverflow

import spock.lang.Unroll

@Unroll

expect:

def dbItem = row["item"]
def dbCategory = row["category"]
def dbSubCategory = row["subcategory"]
def dbBrand = row["brand"]
def dbType = row["type"]

assert dbItem == item
assert (category ?: dbCategory) == dbCategory
