WebSockets server receives data but doesn't send back response

WebSocket doesn't send back a response despite the payLoad of the response is correct. The connection between front end and back end seems fine too. The boolean toggling inside the object array also works fine and does it's job. Any ideas why it isnt sending the JSON back to front end?
--------------------Front-end--------------------
const clientChangeVote = (c) => {
const payLoad = {
method: "changeVote",
clientId: gameData.clients[c].id,
gameId: gameData.id,
};
// voteValue: gameData.clients[c].voteReady,
ws.send(JSON.stringify(payLoad));
};
-----------------Back-end------------------------
if (result.method === "changeVote") {
const gameId = result.gameId;
const clientId = result.clientId;
games[gameId].clients
.filter((x) => x.id === clientId)
.forEach((vote) => (vote.voteReady = !vote.voteReady));
const updatedData = games[gameId].clients;
const payLoad = {
method: "changeVote",
updatedData: updatedData,
};
const game = games[gameId];
console.log(games);
game.clients.forEach((c) => {
console.log(payLoad);
c.connection.send(JSON.stringify(payLoad, getCircularReplacer()));
});
}
function getCircularReplacer() {
const seen = new WeakSet();
return (key, value) => {
if (typeof value === "object" && value !== null) {
if (seen.has(value)) {
return;
}
seen.add(value);
}
return value;
};
}
-----------Inside the respone area. Im using React-----------
const [ws, setWs] = useState(new W3CWebSocket(URL));
useEffect(() => {
ws.onopen = () => {
console.log("Successful connection");
};
ws.onmessage = (message) => {
if (response.method === "changeVote") {
console.log("Vote received");
}
return () => {
ws.onclose = () => {
console.log("Connection closed");
setWs(new WebSocket(URL));
};
};
}, [ws.onmessage, ws.onopen, ws.onclose]);

Change ws.onmessage() :
ws.onmessage = (message) => {
let response = JSON.parse(message.data)
if (response.method === "changeVote") {
console.log("Vote received");
}
if not works add a comment.

How to test firebase callable function with firestore

I have a firebase callable function like
exports.getUserInfo = functions.https.onCall(async (data, context) => {
const userIdRef = store.collection('UserID').doc('Document');
let res = null;
try {
res = await store.runTransaction(async t => {
const doc = await t.get(userIdRef);
currentUserId = doc.data().ID;
const newUserIdNum = currentUserId + 1;
await t.update(userIdRef, {ID: newUserIdNum});
let initUserData = {
'userID': newUserId,
}
return initUserData ;
});
console.log('Transaction success');
} catch (e) {
console.error('Transaction failure:', e);
}
return res;
})
but I am not sure how to create unit test about this. I want to mock UserID/Documment before I call
test.wrap(getUserInfo), like
const myFunctions = require('../index.js')
const getUserInfoWrapped = test.wrap(myFunctions.getUserInfo);
var assert = require('assert');
describe('User', function() {
describe('getUserInfo()', function() {
it('should create user', async function() {
// sample code, this won't work
const snapshot = test.firestore.makeDocumentSnapshot({ID: 1001}, 'UserID/Document');
const data = {}
const result = await getUserInfoWrapped (data, {});
assert.equal(result.userID, "1002");
});
});
});
seems this case not covered by firebase document
Reference:
https://firebase.google.com/docs/functions/unit-testing

Spyon method in jest - Cannot spyOn on a primitive value

const onSubmitClick = async () => {
var { isSuccess, result } = await callDispatch();
if (isSuccess) {
setValidStatus(true);
}
};
async function callDispatch() {
const result = call to server;
let isSuccess = result.success || (result.response && result.response.data.success);
return { isSuccess, result };
}
and in my test file
import { EnterPin } from '../pages/enter-pin';
jest.spyOn(EnterPin.prototype, 'callDispatch').mockImplementation(() =>{
return 'true'
})
var button = screen.getByRole('button');
fireEvent.click(button);
but i am getting Cannot spyOn on a primitive value; undefined given
I tried below too but it didnot work
jest.spyOn(EnterPin.prototype, 'callDispatch').mockImplementation(() =>{
return 'true'
})
var button = screen.getByRole('button');
fireEvent.click(button);

How to test promises chain using jest?

I have module executer that will be executed on every api request now i am trying to write cases to unit test that executer. I have promise that returns chain that is being executed based on response. I see issue executing promise in test case , any help here to proper test this use case will be apprecaited.
main.ts
export class Executor {
private passedParam: ILogParams = {} as ILogParams;
constructor(public identity: Identity) {
this._ajv = new Ajv();
}
public execute(moduleName: string): (param1, param2) => any {
const self = this;
// getting rid of the tslint issue with Function
return function(params: any, responseCallback: (param: any , param2: any) => any) {
let _mod;
let _httpRequest;
let _params;
Promise.resolve(getApiModule(self.identity, moduleName))
.then((mod: ModuleBase<any, any>) => {
_mod = mod;
mod.ExecStage = ExecStage.Init;
return mod.init(getHttpModule(self.identity), params);
})
.then((httpRequest: HttpRequestBase) => {
_httpRequest = httpRequest;
if (_mod.Response().Summary.Header) {
throw _mod.Response().Summary;
}
return httpRequest;
})
.then(() => {
// empty the error stack
_mod.objErrorHandler.RemoveAllError();
_mod.ExecStage = ExecStage.Before;
return _mod.before(params);

_mod.ExecStage = ExecStage.Core;
return _mod.core(_params, _httpRequest);
})
.catch((data: any) => {

})
.then((data: any) => {
responseCallback(data, moduleName.substr(moduleName.indexOf('/') + 1));
});
};
}
}

How to use createSpyObj properly

I am trying to test the getDatabase Version function will pass the query as in to the executeQuery function in the getQueryResult() called by getDatabase.
The code is as follows:
`
var RequestHandler = function () {
this.getQueryResult = function (sQuery) {
this.checkConnection();
try {
return this.conn.executeQuery.apply(this.conn, arguments);
} catch (err) {
this.conn.close();
this.conn = null;
throw "unexpected error, please check application trace files for more information";
}
};
this.getDatabaseVersion = function() {
var query = "select top 1 VERSION from M_DATABASE";
return this.getQueryResult(query)[0].VERSION;
};
}
`
The test case that I wrote:
`
var RHandler = $.import("sap.hana.graph.viewer.XS_Backend.js.lib", "RequestHandler").RequestHandler;
describe ("getDatabaseVersion Tests", function (){
var rHandler = null;
var getQueryResult = jasmine.createSpyObj('getQueryResult', ['conn', 'executeQuery', 'close']);
var conn = jasmine.createSpyObj('conn', ['executeQuery', 'close']);
beforeEach(function() {
rHandler = new RHandler();
rHandler.openConnection();
});
function getAllQueries() {
return getQueryResult.conn.executeQuery.calls.allArgs().join(':::');
}
it('should return the databaseVersion and match the query sent to getQueryResult', function() {
rHandler.getDatabaseVersion();
expect(rHandler.getDatabaseVersion()).toEqual("2.00.030.00.1502184660");
expect(getAllQueries()).toEqual(/select top 1 VERSION from M_DATABASE/i);
});
});
`
But it doesn't work at all. I am approaching in a wrong way. Can anyone guide me or let me know what I am doing wrong.

You need something like that:
var RHandler = $.import("sap.hana.graph.viewer.XS_Backend.js.lib", "RequestHandler").RequestHandler;
describe('RequestHandler', () => {
let rHandler = null;
let connection = null
beforeEach(() => {
connection = jasmine.createSpyObj('conn', ['executeQuery', 'close'])
rHandler = new RHandler();
rHandler.conn = connection;
});
describe('getQueryResult', () => {
beforeEach(() => {
spyOn(rHandler, 'checkConnection');
});
it('should check connection', () => {
rHandler.getQueryResult();
expect(rHandler.checkConnection).toHaveBeenCalled();
});
it('should execute query', () => {
connection.executeQuery.and.returnValue('foo');
const actual = rHandler.getQueryResult('bar', 'baz');
// toHaveBeenCalledWithContext
// https://www.npmjs.com/package/jasmine-spy-matchers
expect(connection.executeQuery).toHaveBeenCalledWithContext(connection, 'bar', 'baz');
// or default toHaveBeenCalledWith
expect(connection.executeQuery).toHaveBeenCalledWith('bar', 'baz');
expect(actual).toBe('foo');
});
it('should throw error', () => {
connection.executeQuery.and.throwError(new Error('some error message'));
expect(() => {
rHandler.getQueryResult('bar', 'baz');
}).toThrow('unexpected error, please check application trace files for more information');
expect(rHandler.conn).toBe(null);
});
});
describe('getDatabaseVersion', () => {
it('should return version', () => {
spyOn(rHandler, 'getQueryResult').and.returnValue([{VERSION: '2.00.030.00.1502184660'}])
const actual = rHandler.getDatabaseVersion();
expect(rHandler.getQueryResult).toHaveBeenCalledWith('select top 1 VERSION from M_DATABASE')
expect(actual).toBe('2.00.030.00.1502184660');
});
});
});
