Need help in writing test class for a Call Out with mutiple functions

For example , in below I am trying to get response from service now for  list of tasks assigned to particular and based on details in those tasks, users should be created automatically in Salesforce on click of Submit button on visualforce page. We will pass the group name in VF page. Once the user is created, Permission Set and Permission Set Groups will also be assigend to that user automatically through two separate methods

How do i start for the test class so that all the methods are covered here ?

public class ServiceNowSTask {
    
    public String snow_user{get;set;}
    public String snow_pwd{get;set;}
    public integer sctasknum{get;set;}
    Public integer iCount = 0;
    
    public void servicenowcallout(){
    
    try{
        List<User> lstNewUser = new List<User>();

I have just started learning LWC and trying to display a picklist of Account Names in a LWC ComboBox and the selected value should be displayed on the Placeholder and on a text line below the placeholder.

The issue is I am seeing the dropdown values but the selected value is not being displayed on the placeholder and not even on the text line below it. What am i doing wrong. 

Below is my code

JS Code

import { LightningElement, track, wire } from 'lwc';
import getAccList from '@salesforce/apex/test_LWCWireDemo.getAccList';

export default class Test_comboboxDemo extends LightningElement {

    @track value = ""
    @track accoption = [];

    get options(){
        return this.accoption;
    }

    connectedCallback(){
        getAccList()
        .then(result => {
            let arr = [];
            for(var i=0;i<result.length;i++){
                arr.push({value :result[i].Name, label :result[i].ID});
            }
            this.accoption = arr;

        })
        .catch(error => {
            console.log("error occurred");
        })
        
    }

    handleChange(event){
        this.value = event.detail.value;
    }

}

<template>
    <lightning-card title="Combo Box Demo">

        <lightning-combobox label="Account Status"
                            value={value}
                            placeholder="Select Account"
                            options={options}
                            onchange={handleChange}>
        </lightning-combobox>

        <p>Select Value is: {value}</p>
    </lightning-card>
</template>

public class test_LWCWireDemo {
    
	@AuraEnabled
    public static List<Account> getAccList(){
        
        List<Account> accList = [Select ID, Name from Account];
        return accList;
    }
    
}

I am trying to update the Work Order Line Item as DONE but I am getting a validation error as

The flow tried to update these records: 0WO8b000000r5qnGAA. This error occurred: CANNOT_EXECUTE_FLOW_TRIGGER: We can't save this record because the “NTWSM Work Order Last Completed Step Updated” process failed. Give your Salesforce admin these details. This error occurred when the flow tried to update records: FIELD_INTEGRITY_EXCEPTION: The Start Date must be equal to or earlier than the End Date.: Start Date

There is no such custom vaidation rule written and its not allwoing us to makr this Item as Done even though we are putting End Date greater than Start Date

Any workaround to bypass this and update it
