Jest issue when I run the test cases via the command

I am newbie on Jest and I have the following issue when I execute the command
npm test
I have the following files
functions.js
const functions = {
add: (num1,num2) => num1 + num2
};
module.exports = functions;
and the functions.test.js
const functions = require('./functions');
test(`Adds 2 + 2 to equal 4`, ()=>{
expect(functions.add(2,2)).toBe(4);
});
my package.json has the following context
{
"name": "jest-tutorial",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "jest"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"jest": "^29.2.2"
}
}
I havent found a lot of resources on the internet regarding the error I just try to remove the dot (.) character from the node_modules/jest
and the output of the console (error) is below
> jest-tutorial#1.0.0 test
> jest
C:\Users\agiallelis\node_modules\jest-cli\build\run.js:129

Schemaglue throws error "No schemas found under the path '${path.resolve(schemaFolderPath)}'" when running webpack build file

I have graphql schema and resolvers in folder app/GraphQL and app.js in root folder. Root folder have files in below format:
app
GraphQL
Sample1
sample1.graphql
sample1.resolver.js
Sample2
sample2.graphql
sample2.resolver.js
app.js
And in app.js I glue the schema from app/GraphQL as shown below using library schemaglue:
const schemaglue = require("schemaglue");
const { schema, resolver } = schemaglue("app/GraphQL");
Now when I create build with webpack it creates folder in root named build and have file it in names bundle-app.js which is the build file. But when I run this file using command node ./build/bundle-app.js it throws below error and I dont know how to resolve it:
C:\Users\sai\Projects\webpack build\node_modules\schemaglue\index.js:87
throw new Error(`Missing GraphQL Schema: No schemas found under the path '${path.resolve(schemaFolderPath)}'`)
^

Error when import firebase-functions-test when testing with mocha

I am trying to setup a Firebase Cloud Functions repo to run mocha test. However, it throws the following error when I use import * as firebase from "firebase-functions-test"; or const firebase = require("firebase-functions-test")();. You can see in my code that I haven't even called the actual firebase functions yet so I think this a setup issue.
Question: What change do I need to make mocha test running for Firebase Functions testing using import syntax?
Working test code
import { assert } from "chai";
describe("Sanity Check", () => {
it("should pass", () => {
assert.equal(0, 0);
});
});
Failed Test Code using require
const test = require("firebase-functions-test")();
import { assert } from "chai";
describe("Sanity Check", () => {
it("should pass", () => {
assert.equal(0, 0);
test.cleanup();
});
});
Failed code using import
import * as firebase from "firebase-functions-test";
import { assert } from "chai";
const test = firebase();
describe("Sanity Check", () => {

test.cleanup();
});
});

node js MODULE_NOT_FOUND error in node_modules

I am new to javascript and I am having import issues.
I have installed the jquery.csv lib as npm i jquery.csv but then node is not able to import it. (this was the procedure described in https://github.com/typeiii/jquery-csv)

Why am I getting this error?

It seems their documentation is incorrect. You need to require the npm module like this:
const csv = require('jquery-csv');

})).pipe(eslint.format());
});

Please check your node version. You are using object destructuring which is available from Node v6. If you're using node v4 then this might not work.
