00-deploy-mocks.js

const { developmentChains } = require("../helper-hardhat-config")

 //VRFCoordinator constructor takes in _baseFee _gasPricelink
//each request for Random number on Rinkeby will cost 0.26 lINK

const BASE_FEE = ethers.utils.parseEther("0.25") // 
const GAS_PRICE_LINK = 1e9 // CALCULATED VALUE ON THE GAS PRICE OF THE CHAINS



module.exports = async function ({ getNamedAccounts, deployments }){
     
    const { deploy, log } = deployments
    const { deployer }  = await getNamedAccounts()
    const args = [BASE_FEE, GAS_PRICE_LINK]

    if (developmentChains.includes(network.name)) {
         log("Local network detected! Deploying mocks...")
         //deploy a mock vrfcoordinator...
         await deploy ("VRFCoordinatorV2Mock", {
               from: deployer,
               log: true,
               args: args,

         })
         log("Mocks Deployed")
         log("..................................")
         
    }

    module.exports.tags = ["all", "mocks"]

}

module.exports.tags should be outside the first module.exports.It should be something like this:

module.exports = async function ({ getNamedAccounts, deployments }){
     
    const { deploy, log } = deployments
    const { deployer }  = await getNamedAccounts()
    const args = [BASE_FEE, GAS_PRICE_LINK]

    if (developmentChains.includes(network.name)) {
         log("Local network detected! Deploying mocks...")
         //deploy a mock vrfcoordinator...
         await deploy ("VRFCoordinatorV2Mock", {
               from: deployer,
               log: true,
               args: args,

         })
         log("Mocks Deployed")
         log("..................................")
         
    }

}
module.exports.tags = ["all", "mocks"]
//it should be on its own outside the first one

Your code works when you run yarn hardhat deploy because hardhat is not looking at the tags.Its looking at the module.exports .
When testing we are deploying using tags which should be in separate module.exports.tags

It throwed this error

Copy this in your unit test file:

beforeEach(async () => {
              accounts = await ethers.getSigners() // could also do with getNamedAccounts

              //   deployer = accounts[0]
              player = accounts[1]
              await deployments.fixture(["mocks", "raffle"]) // Deploys modules with the tags "mocks" and "raffle"
              vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock") // Returns a new connection to the VRFCoordinatorV2Mock contract
              raffleContract = await ethers.getContract("Raffle") // Returns a new connection to the Raffle contract
              raffle = raffleContract.connect(player) // Returns a new instance of the Raffle contract connected to player
              // If below getter functions are required, uncomment them:
              // Uncomment this if needed: raffleEntranceFee = await raffle.getEntranceFee()
              // Uncomment this if needed: interval = await raffle.getInterval()
          })

Let me know if this fixes your problem

Were the changes pulled to your local repo? If so, I will check it

krakxn Jul 23, 2022

@Maakai123 I made a PR again, do the same process again. It should most likely fix the problem

Note: Please make sure your local repo has the updates of your GitHub repo by git pull, do not forget this

@alymurtazamemon Could you check this further? The VRFCoordinator... in the contract seems to return interval as 1

@alymurtazamemon i am having same error, can you help me out too

const { networkConfig, developmentChains } = require("../helper-hardhat-config")
const { network, getNamedAccounts, deployments } = require("hardhat")
const { verify } = require("../utils/verify")
module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId

    let ethUsdPriceFeedAddress
    if (chainId == 31337) {
        const ethUsdAggregator = await deployments.get("MockV3Aggregator")
        ethUsdPriceFeedAddress = ethUsdAggregator.address
    } else {
        ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]
    }
    const args = [ethUsdPriceFeedAddress]

    const FundMe = await deploy("FundMe", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmations: network.config.blockConfirmation || 1,
    })

    log(`FundMe deployed at ${FundMe.address}`)

    if (!developmentChains.includes(network.name) && process.env.API_KEY) {
        await verify(FundMe.address, args)
    }
    {
        await verify(FundMe.address, [ethUsdPriceFeedAddress])
    }
}

module.exports.tags = ("all", "FundMe")

the above is 01-deploy-fund-me.js
and below is fundMe.test.js

const { deployments, getNamedAccounts, ethers } = require("hardhat")
const { assert } = require("chai")

describe("fundMe", async function () {
    let hello
    let deployer
    let MockV3Aggregator
    beforeEach(async function () {
        deployer = (await getNamedAccounts()).deployer
        await deployments.fixture(["all"])
        hello = await ethers.getContract("FundMe", deployer)
        MockV3Aggregator = await ethers.getContract(
            "MockV3Aggregator",
            deployer
        )
    })
    describe("constructor", async function () {
        it("sets the aggregator addresses correctly", async function () {
            const response = await hello.getPriceFeed()
            assert.equal(response, MockV3Aggregator.address)
        })
    })
})

the error is below:
