testing

[two-ticks]

I want to test whether add method is called or not. I have tried these ways but all are giving the same error.

it('add should be called', () => {
  const tex = createTeX('2^2');
  const spy = jest.spyOn(tex, 'add');
  tex.add();
  expect(spy).toHaveBeenCalled();
  //expect(tex.position()).toEqual([10, 20]);
});

it('add should be called', () => {
  const tex = createTeX('2^2');
  const element = createDiv();
  global.createDiv = function(html){return element}
  const spy = jest.spyOn(tex, 'add');
  tex.add();
  expect(spy).toHaveBeenCalled();
  //expect(tex.position()).toEqual([10, 20]);
});

it.skip('play should be called', () => {

[two-ticks]

I tried this and it's working.

it('play should be called', () => {
  const tex = createTeX('2^2');
  const spy = jest.spyOn(tex, 'play').mockImplementation(()=>{});
  tex.play();
  expect(spy).toHaveBeenCalled();
});
