Moving on, it’s time to define our first test. We will check whether the addPlayer() function operates properly. Put the following code inside the first contract function in your test file:

it("..should ADD players", async () => {  let Cp = await Cplayer.new();  for (let i = 0; i < 3; i++) {    await Cp.addPlayer("player" + i, 123, { from: accounts[i] });    const P = await Cp.players.call(accounts[i]);    assert.equal(P[2], accounts[i], "player not added");  }  });
