Jest error when testing Vue "Cannot read property 'dispatch' of undefined"?

Question

Vue.js

good afternoon, suddenly someone can tell me, I wrote the first test,
but for some reason Jest swears "Cannot read property 'dispatch' of undefined" although I do not interact with the store in the test itself, I just check the text of the element, I don’t understand a little how to get around this error:



test :

import { mount } from "@vue/test-utils";
import Cards from "@/components/Cards.vue";

describe("testing Cards", () => {
  it("help text renders correctly", () => {
    const wrapper = mount(Cards);
    const loaderTextElement = wrapper.find(".cards__help");
    expect(loaderTextElement.text()).toBe("Увы, нет подходящих городов");
  });
});

component :

setup() {
    const store = useStore();
    store.dispatch("fetchCities");

    const bigCardsList = computed(
      (): ObjectOfCity[] => store.getters.bigCardsList
    );

    const textOfHelp = computed((): string =>
      filters.value.length
        ? "<p>Увы, нет подходящих городов</p>"
        : "<p>Перетащите сюда города, <br />погода в которых вам интересна</p>"
    );

    return {
      bigCardsList,
      textOfHelp,
    };
  },
