how to mock get function in jest code example

Example 1: how to mock a library in jest

import randomColor from "randomcolor";


jest.mock("randomColor", () => {
  return {
    randomColor: () => {
      return mockColor('#123456');
    }
  }
});
let mockColor = jest.fn();

Example 2: jest mock call

test("mock.calls", () => {
  const mockFn = jest.fn();
  mockFn(1, 2);

  expect(mockFn.mock.calls).toEqual([[1, 2]]);
});
