Error While testing FundMe.test.js [Error: No Contract deployed with name FundMe]

[Mumtaz503]

Hi, I'm trying to test the constructor of "FundMe.sol" and I'm getting the following error.

I have tried changing the module.exports script in the "00-deploy.js" (For Mocks) and "01-deploy.js" (Main Deploy Scripts). Here's my code for FundMe.test.js. Any help will be appreciated. :)

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

describe("Funds", 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 address correctly", async function () {
        const response = await fundMe.getPriceFeed();
        assert.equal(response, mockV3Aggregator.address);
    });
});

});
`

Here's my code for FundMe.sol

`// SPDX-License-Identifier: MIT

@Mumtaz503 Remove the default from these lines;

module.exports = deploymentFtn;

[Mumtaz503]

I already tried that. The issue still persists.

[alymurtazamemon]

@Mumtaz503 I tested your code, you must be facing some other issue.

[alymurtazamemon]

@Mumtaz503 You can see this;

You must be facing another issue in the test which you can fix with this line;

- const response = await fundMe.getPriceFeed();
+ const response = await fundMe.PriceFeed();

[Mumtaz503]

Yes I checked. I couldn't access my tags in deploy scripts properly. That issue was resolved hopefully this'll work now.
