Lesson 14 - basicNft.test.js

[DaurenNox]

Having issue with Unit test of basicNFT.

Here is my code:

const { inputToConfig } = require("@ethereum-waffle/compiler")
const { assert } = require("chai")
const { network, deployments, ethers } = require("hardhat")
const { developmentChains } = require("../../helper-hardhat-config")

!developmentChains.includes(network.name)
?describe.skip
:describe("Basic NFT Unit test", function() {
    let BasicNFT, deployer
    
    beforeEach(async () => {
        accounts = await ethers.getSigners()
        deployer = accounts[0]
        await deployments.fixture(["BasicNFT"])
        BasicNFT = await ethers.getContract("BasicNFT")
    })

    it("Allows users to mint an NFT, and updates appropriately", async function() {
        const txResponse = await BasicNFT.mintNft()
        await txResponse.wait(1)
        const tokenURI = await BasicNFT.tokenURI(0)
        const tokenCounter = await BasicNFT.getTokenCounter()

        assert.equal(tokenCounter.toString(), "1")
        assert.equal(tokenURI, await BasicNFT.TOKEN_URI())
    })
})

Here is the error I get Error: No Contract deployed with name BasicNFT

Files compile and deploy fine. Have tried copying Patrick's file from the repo still get the same error. Have tried doing hardhat clean still get the same error.

Thank you for your help!

upload your basicNft deploy script

It's there!

this is the test file ,am asking for 01-deploy-basicNft.js

my bad

const {network, getNamedAccounts} = require("hardhat")
const {developmentChains} = require("../helper-hardhat-config")
const {verify} = require("../utils/verify")

module.exports = async function({getNamedAccounts,deployments}) {
    const {deploy, log} = deployments
    const {deployer} = await getNamedAccounts()
    

    log("------------------------------")

    const args = []
    const basicNft = await deploy("BasicNFT", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmation: network.config.blockConfirmations || 1,

    })

    if(!developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY) {
        log("Verifying....")
        await verify(basicNft.address, args)
    }
}

after the module.exports add module.exports.tags=["all","BasicNFT"]. await deployments.fixture(["BasicNFT"]) is the line used to deploy during tests.It will only deploy if what is mentioned in the module.exports.tags is what is inside the fixtures.Your code should look something like this

const {network, getNamedAccounts} = require("hardhat")
const {developmentChains} = require("../helper-hardhat-config")
const {verify} = require("../utils/verify")

module.exports = async function({getNamedAccounts,deployments}) {
    const {deploy, log} = deployments
    const {deployer} = await getNamedAccounts()
    

    log("------------------------------")

    const args = []
    const basicNft = await deploy("BasicNFT", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmation: network.config.blockConfirmations || 1,

    })

    if(!developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY) {
        log("Verifying....")
        await verify(basicNft.address, args)
    }
}
module.exports.tags=['all','BasicNft']

I added all because at somepoint you might need to deploy all deploy files with all tag
