Contract method is not found

问题

So I'm working out of index.ts where my contract code is and utils.js where I added my methods and I'm testing my functions in the console but receive the above response.

index.ts

import { Context, logging, storage, PersistentMap } from 'near-sdk-as'
import { string } from 'prop-types';

// Key value pair
// Value = array ; Key = voter ID
let votersReg= new PersistentMap<string, bool>("Voters Registration");
let candidateReg= new PersistentMap<string, i32>("Candidate Registration");

// Context.sender == 'usernmae.testnet'

export function addVote(candidate:string):i32{
    if(!votersReg.contains(Context.sender)){
        votersReg.set(Context.sender, true)
        if(!candidateReg.contains(candidate)){
            candidateReg.set(candidate, 1)
        }
        else{
            let currentCount=candidateReg.getSome(candidate);
            currentCount += 1;
            candidateReg.set(candidate, currentCount);
        }  
    }
    else{
        logging.log("You have already voted!")
    }
    return candidateReg.getSome(candidate)
}

export function getVotes(candidate:string):i32{
    if(candidateReg.contains(candidate)){
        return candidateReg.getSome(candidate)
    }
    else {return 0}
}

utils.js

import { connect, Contract, keyStores, WalletConnection } from 'near-api-js'
import getConfig from './config'

//const nearConfig = getConfig(process.env.NODE_ENV || 'development')
const nearConfig = getConfig('testnet')

// Initialize contract & set global variables
export async function initContract() {
  // Initialize connection to the NEAR testnet
  const near = await connect(Object.assign({ deps: { keyStore: new keyStores.BrowserLocalStorageKeyStore() } }, nearConfig))

  // Initializing Wallet based Account. It can work with NEAR testnet wallet that
  // is hosted at https://wallet.testnet.near.org
  window.walletConnection = new WalletConnection(near)

  // Getting the Account ID. If still unauthorized, it's just empty string
  window.accountId = window.walletConnection.getAccountId()

  // Initializing our contract APIs by contract name and configuration
  window.contract = await new Contract(window.walletConnection.account(), nearConfig.contractName, {
    // View methods are read only. They don't modify the state, but usually return some value.
    viewMethods: ['getVotes'],
    // Change methods can modify the state. But you don't receive the returned value when called.
    changeMethods: ['addVote'],
  })
}

export function logout() {
  window.walletConnection.signOut()
  // reload page
  window.location.replace(window.location.origin + window.location.pathname)
}

export function login() {
  // Allow the current app to make calls to the specified contract on the
  // user's behalf.
  // This works by creating a new access key for the user's account and storing
  // the private key in localStorage.
  window.walletConnection.requestSignIn(nearConfig.contractName)
}

testing addVote() with await window.contract.addVote({candidate: "dummy"}) returns

testing getVotes() with await window.contract.getVotes() returns

I am not exactly sure what is going on here. I was under the impression I did not need to deploy my contracts prior to testing, perhaps this is what is screwing things up but I thought deploying contracts was a finality step. Thanks in advance for any help!

You do need to deploy your contracts in order to test them. You will have to do this for each function you add for it to be available in the frontend.
