Всем привет ,не могли бы подсказать где ошибка и почему не проходит тест?

class World {

  constructor() {

  }

  createPowerPlant() {
    let powerPlant = new PowerPlant();

    return powerPlant;
  }

  createHousehold() {
    let household = new Household();

    return household;
  }

  connectHouseholdToPowerPlant(household, powerPlant) {
    household.connecting(powerPlant.connectFromPowerPlant());
  }

  connectHouseholdToHousehold(household1, household2) {

  }

  disconnectHouseholdFromPowerPlant(household, powerPlant) {
    household.disconnect(powerPlant.disconectFromPowerPlant());
  }

  killPowerPlant(powerPlant) {

  }

  repairPowerPlant(powerPlant) {

  }

  householdHasEletricity(household) {
    return household.statusCheck();
  }
}

class Household {
  constructor() {
    this.isConnectToPowerPlant = false;
  }

  connecting(connectStatus) {
    this.isConnectToPowerPlant = connectStatus;
  }

  disconnect(disconectStatus) {
    this.isConnectToPowerPlant = disconectStatus;
  }

  statusCheck() {
    return this.isConnectToPowerPlant;
  }
}

class PowerPlant {
  constructor() {
    this.listOfKilledPlants = [];
    this.isActive = true;
  }

  connectFromPowerPlant() {
    return true;
  }

  disconectFromPowerPlant() {
    return false;
  }
}
