I have a LWC Component which is used for record upload process.

Below is my LWC Javascript code:

import { LightningElement, api } from 'lwc';
import file1 from '@salesforce/apex/customLwcController.file1';
import file2 from '@salesforce/apex/customLwcController.file2';

    export default class customRecordProcess extends LightningElement {
        @api customRecordId;
        fileName = null;
        customFileId = null;
        showModalButton = false;
        modalButtonLabel = '';
        showFileName = false;
        customFileIds = [];
        isModalOpen = false;
    
        onUploadComplete(file, result) {
            console.log('onUploadComplete');
            this.customFileIds.push({Id: result, Title: file.name});
            if (this.fileName === null) { 
                this.fileName = file.name;
                this.customFileId = result;
            }
            this.updateDisplayText();
        }
    
        handleFileUpload(event){
            let file = event.target.files[0];
            let reader = new customReader();
    
            file.sObject
            }
            }

Below is my HTML Code:

<template>
        <div class="slds-grid">
            <lightning-formatted-text class="left-col" value=""></lightning-formatted-text>
            
            <div class="middle-col">
                <lightning-input
                    class="inp middle-col" 
                    type="file"
                    onchange={handleFileUpload}>
                </lightning-input>
            </div>

            </template>

Now, I need to compile this component using Jest Test class before deploying the changes
.
Being new to JS, I am in process of exploring Jest Test Classes. Can anyone please help me out with the test class to cover my above given component?
