Lession 7 "Deployment chain is not defined"

[Sakana-xc]

Hi guys,
After I wrote the staging test, I am tring to run yarn hardhat test --network rinkeby, but it returns "deploymentChain is not defined".
This all happened after I worte developmentChains.includes(network.name) ? describe.skip : describe("FundMe Staging Tests", async function () {

Before this my unit test works fine, now my unit test has the same problem. Even in my scripts, when I try to run yarn hardhat run scripts /fund.js it also says "deploymentChain is not defined".

Here are my codes below:

const { assert } = require("chai")
const { network, ethers, getNamedAccounts } = require("hardhat")
const { developmentChains } = require("../../helper-hardhat-config")

developmentChains.includes(network.name)
    ? describe.skip
    : describe("FundMe Staging Tests", async function () {
          let deployer
          let fundMe
          const sendValue = ethers.utils.parseEther("0.1")
          beforeEach(async () => {
              deployer = (await getNamedAccounts()).deployer
              fundMe = await ethers.getContract("FundMe", deployer)
          })

          it("allows people to fund and withdraw", async function () {
              await fundMe.fund({ value: sendValue })
              await fundMe.withdraw()

              const endingFundMeBalance = await fundMe.provider.getBalance(
                  fundMe.address
              )
              console.log(
                  endingFundMeBalance.toString() +
                      " should equal 0, running assert equal..."
              )
              assert.equal(endingFundMeBalance.toString(), "0")
          })
      })

Here is my helper-config.js

const networkConfig = {
    31337: {
        name: "localhost",
    },
    4: {
        name: "rinkeby",
        ethUsdPriceFeed: "0x8A753747A1Fa494EC906cE90E9f37563A8AF630e",
    },

    137: {
        name: "polygon",
        ethUsdPriceFeed: "0xF9680D99D6C9589e2a93a78A04A279e509205945",
    },
}

const developmentChains = ["hardhat", "localhost"]
const DECIMALS = 8
const INITIAL_ANSWER = 200000000000

module.exports = {
    networkConfig,
    developmentChains,
    DECIMALS,
    INITIAL_ANSWER,
}

Thanks guys.

• First, check if the Rinkeby RPC URL is okay in the .env file
• If it is okay: yarn hardhat deploy --network rinkeby
• Now, run: yarn hardhat test --network rinkeby

Hi Krakxn, the Rinkeby URL is fine, I can deploy contracts at rinkeby, but if I run test, I get ReferenceError: developmentChains is not defined at Object.<anonymous> (/Users/cong1/Documents/HH-FCC/Hardhat-FundMe-fcc/test/unit/FundMe.test.js:4:1) this.
Is the code alright?

[krakxn]

Made a PR.

[krakxn]

Made another PR -- you can merge them now. Pull the changes and let me know if it fixes your problem.

Hi krakxn, sorry for the delayed response, I've been out for a while. Yea add const { developmentChains } = require("../../helper-hardhat-config") indeed solve my problem, I forget commandyarn hardhat test runs both of the two test. Thanks, by the way do you know why my terminal get extremelly slow when I run test command? It can takes up to 3-5 mins, other commands are all fine and excuted in seconds.

[krakxn]

Awesome, all the best!

Note: Don't know, are you running on a old system?

@SakanaSachi

Add this:

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

Your unit test file has missed this.

Also remove the from mock deploy file

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

[alymurtazamemon]

@SakanaSachi I have checked your unit test now, this problem is resolved after adding the above line, but it has many other issues that you should solve, and if feel an issue then again creates a discussion for that.

Also deployed locally and its works.

Hi Ali, thanks for the help and sorry for the late response. Yea indeed it solves my problem, I think other problems are because I messed up the parameters when I try to replace them since I changed them all @ fundme.sol. I rewrote the unit test and now solves most of them. Btw why runing commend "test" can be extremely slow? It takes up to 3-5 mins.
