Lesson 7:Error: No Contract deployed with name mockV3Aggregator

[umairahmed88]

this is my code
const { deployments, ethers, getNamedAccounts } = require("hardhat");
const { assert } = require("chai");

describe("FundMe", async function () {
let fundMe;
let deployer;
let mockV3Aggregator;

beforeEach(async function () {
    deployer = (await getNamedAccounts()).deployer;
    await deployments.fixture(["all"]);
    fundMe = 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 fundMe.priceFeed();
        assert.equal(response, mockV3Aggregator.address);
    });
});

});

This is the error

Hi @umairahmed88 ,

I think you forgot to put the capital M at the start of MockV3Aggregator.
Try this instead : mockV3Aggregator = await ethers.getContract("MockV3Aggregator", deployer)

Cheers 😄
