JS Testing and Web3 referencing contract at deployed address

Question

I have a Contract Factory and a sub contract, and now i want to test the newly created sub contract. This one should be pretty simple, I hope.

it("test CoinNewCoin - Test Created Coin ", function (){

    var fromOwner = accounts[0];
    var coinFactory;
    var coinNewCoin;
    return CoinFactory.deployed().then((instance) => {
        coinFactory = instance;
    }).then(() => {
    return coinFactory.getCoinAddress(fromOwner, {from: fromOwner});
    }).then((result) => {
        console.log(result);
    return CoinNewCoin.at(result).then((instance) => {
    }).then((instance) => {
        console.log(instance); // this is the undefined.
        coinNewCoin = instance;
        return coinNewCoin.getAuthorizationKey();
    })
    }).then((result) => {
        console.log(result);
    });
});

edit: scripting updated.

Answer 1

return CoinNewCoin.at(result).getAuthorizationKey();

The at(address), was the key. thanks -goodvibration!

it("test CoinNewCoin - Test Created Coin ", function (){

    var fromOwner = accounts[0];
    var coinFactory;
    var coinNewCoin;
    var coinAddress;
    return CoinFactory.deployed().then((instance) => {
        coinFactory = instance;
    }).then(() => {
        return coinFactory.getCoinAddress(fromOwner, {from: fromOwner});
    }).then((result) => {
        return CoinNewCoin.at(result).getAuthorizationKey();
    }).then((result) => {
        var testVal = result.toString().split(",");
        assert.equal("00000000000000000000000000000000",web3.toAscii(testVal[0]), "Coin contract is was not created, fail!")
    });
});
