How would you write an integration test for Integrations.s.sol?

Came across your repo and I am stuck on the problem:
There are three contracts -
import {CreateSubscription, FundSubscription, AddConsumer} from "../../script/Interactions.s.sol";
This is my soln to the CreateSubscription

function testCreateSubscriptionReturnsSubId() public {
        //Arrange
        CreateSubscription createSubscription = new CreateSubscription();
        uint64 testSubId = createSubscription.createSubscription(
            vrfCoordinator,
            deployerKey
        );
        //Act
        vm.recordLogs();
        VRFCoordinatorV2Mock(vrfCoordinator).createSubscription();
        Vm.Log[] memory entries = vm.getRecordedLogs();
        bytes32 subId = entries[0].topics[1];
        console.log("subId:", uint64(uint160(uint256(subId))));
        console.log("testSubId: ", testSubId);

        //Assert
        assert(testSubId == (uint64(uint160(uint256(subId))) - 1));
        //The mock gives the next subscriptionID! see the working below:
        //function createSubscription() external override returns (uint64 _subId) {
        //s_currentSubId++;
    }

Is that a valid approach?
Also, how do the test for the other two?
Thanks for your time.
