Sinon Spy to check function has been called

I am trying to use sinon.spy() to check that a function has been called. The function is called getMarketLabel and it returns marketLabel and accepts it into the function. I need to check that getMarketLabel has been called. I actually call getMarketLabel in one place, like so: {getMarketLabel(sel.get('market'))} The code I have so far is:

describe('Check if it has been called', () => {
  let spy;
  beforeEach(() => {
    spy = sinon.spy(getMarketLabel, 'marketLabel');
  })
  it('should have been called', () => {
    expect(spy).to.be.calledWith('marketLabel');
  });
});
