Mock Contracts

[vicjuma]

Hello, this is on a lighter note😊. Is there anything special about a mock contract other than inheritance except this time it is on an interface? With maybe the inability to use virtual and override keywords? Just wondering 😊. Otherwise, 👍 to Patrick and the entire Cyfrin community.

Hello @vicjuma, I don't understand your question. Please break it down more maybe I will understand it.

@EngrPips it was just an observation because I have reached this point

contract MockV3Aggregator is AggregatorV3Interface {}

function getAnvilEthConfig() public returns (NetworkConfig memory) {
        if(activeNetworkConfig.priceFeed != address(0)) {
            return activeNetworkConfig;
        }
        // Deploy the mock then return the mock addresses
        vm.startBroadcast();
        MockV3Aggregator mockV3Aggregator = new MockV3Aggregator(NUMBER_OF_DECIMALS, PRICE_OF_ETH_IN_USD);
        vm.stopBroadcast();
        NetworkConfig memory anvilEthConfig = NetworkConfig(address(mockV3Aggregator));
        return anvilEthConfig;
    }

Just observed that we are performing AggregatorV3Interface interface inheritance on our MockV3Aggregator contract. There are no issues though. Everything is 100% awesome.

Oh, I see. You are just pointing out your observation and not asking a question.

Yes. It is a great experience😊

Indeed, Programming is amazing.
