import { listRegions } from "../src/core/regions";
import { totalRegionsCount } from "../tools/constants";

describe("listRegions", () => {
  let regions: ReturnType<typeof listRegions>;

  beforeAll(() => {
    regions = listRegions();
  });

  it("should list all 18 regions", () => {
    expect(regions).toBeDefined();
    expect(Array.isArray(regions)).toBe(true);
    expect(regions.length).toBe(totalRegionsCount);
  });
