import { toHaveReturned } from "https://deno.land/x/unitest@v1.0.0-beta.82/mod.ts";

Use .toHaveReturned that the mock object successfully returned at least one time

import { expect, fn, test } from "https://deno.land/x/unitest@$VERSION/mod.ts";

test("passes when mock object returned at least once", () => {
  const mockObject = fn(() => true);
  expect(mockObject).not.toHaveReturned();
  mockObject();
  expect(mockObject).toHaveReturned();
});
