Vue testing a component that uses composables

Question

I'm using vitest to put together unit tests for components in my web app. I've run into an issue where my component uses a composable to get some state variables, and the composable is undefined when I run the test. Here is how the component uses the company composable:

const coreValueOptions = company()?.core_values.map((value: any) =>
  value.label.replace(/#/gi, ""),
);

I've tried mocking the composable here in the test, and this doesn't quite work, it only makes it so if I call the composable directly it returns 100, but if the composable is called through the CoreModalFilters component, it doesn't work.

import { describe, test, expect } from "vitest";
import { shallowMount } from "@vue/test-utils";
import CoreModalFilters from "../../components/core/modal/CoreModalFilters.vue";
import { company } from "../../composables/store";

const mock = vi.hoisted(() => {
    return {
      company: vi.fn(),
    };
  });

  vi.mock("../../composables/store", () => ({
    company: mock.company,
  }));
  vi.mocked(company).mockReturnValue(100);

describe("CoreModalFilters and all variants render correctly", async () => {

  test("correctly renders CoreModalFilter with default props", async () => {
    const wrapper = shallowMount(CoreModalFilters, {
      propsData: {
        showModal: true,
      },
    });
    // const html = wrapper.html();
  });
});

and here are the composables

export const company = () => {
  return useStore().company;
};
