Setting up single-player tests before adding spinner

I did that here: https://jsfiddle.net/Lqe5youb/2/

    it("is called with the video element", function() {
      //given 
      const video = document.createElement("video");
      
      //when 
      videoPlayer.addPlayer(video);

      //then
      expect(player.m).toBe(video);
    });
  });
});

Is this then changed to video where we have the test pass?

player = new YT.Player(null, config);

passes: player = new YT.Player(video, config);
