Truffle Test ReferenceError: accounts not defined

[degbuniwe]

I am following an Election.sol tutorial and when I tried to test the function below, I get ReferenceError : accounts not defined. I'm not sure how to fix this.

var Voting = artifacts.require("./Voting.sol");

contract("Voting", function(accounts){ var votingInstance;

//to check initialisation

it("initialises with two candidates", function() {
    return Voting.deployed().then(function(instance){
        return instance.candidatesCount();
    }).then(function(count){
        assert.equal(count, 2);
    });
});

});

it("it initialises the candidates with the correct values", function() {
    return Voting.deployed().then(function(instance) {
        votingInstance = instance;
        return votingInstance.candidates(1);

    }) .then(function(candidate) {
        assert.equal(candidate[0], 1, "contains the correct id");
        assert.equal(candidate[1], "Richard Denton", "contains the correct name");
        assert.equal(candidate[2], 0, "contains the correct vote count");
        return votingInstance.candidates(2);
    }).then(function(candidate){
        assert.equal(candidate[0], 2, "contains the correct id");
        assert.equal(candidate[1], "Jeff Bridges", "contains the correct name");
        assert.equal(candidate[2], 0, "contains the correct vote count");
    });

});
           it("allows a voter to cast a vote", function() {
          return Voting.deployed().then(function(instance) {
          votingInstance = instance;
          candidateId = 1;
        return votingInstance.vote.call(candidateId, { from: accounts[0] });
}).then(function(receipt) {
  assert.equal(receipt.logs.length, 1, "an event was triggered");
  assert.equal(receipt.logs[0].event, "votedEvent", "the event type is correct");
  assert.equal(receipt.logs[0].args._candidateId.toNumber(), candidateId, "the candidate id is correct");
  return votingInstance.voters(accounts[0]);
}).then(function(voted) {
  assert(voted, "the voter was marked as voted");
  return votingInstance.candidates(candidateId);
}).then(function(candidate) {
  var voteCount = candidate[2];
  assert.equal(voteCount, 1, "increments the candidate's vote count");
})

});

Try the following, if you haven't already sorted it:

contract("Voting", (accounts) => {
