How to mock methods that are arrow functions

[grischenko-v]

Try to test calling method width parameter,

export class TestArrowMockStore {
    test = (_value: number) => {};
}

describe('Mocking arrow function tests', () => {
    const store = mock(TestArrowMockStore);
    when(store.test(12)).thenReturn();

    const storeInstance = instance(store);

    test('store test', () => {
        storeInstance.test(12);
        verify(store.test(12)).once();
    });
});

but i get this:

Mocking arrow function tests › store test

    TypeError: storeInstance.test is not a function

      test('store test', () => {
          storeInstance.test(12);
                                       ^
          verify(store.test(12)).once();
  });
| });

What I do wrong?
