Test Class for Twilio SMS Help Needed!

Hi all,
I have working Code the sends an SMS  via Apex and Twilio, Great stuff. The trouble I am having is writing the Tests and I just need a little help. I don't do near enough Apex for my liking and I am feeling it here. 

IAny help/pointers would be most appreciated. 

Apex class:
public with sharing class Twilio {
    
    Public string text1 {get;set;}
    public boolean showmessage{get;set;}
    public string selectedvalue {get;set;} 
    
    private final contact acct;
    public Twilio(){}
    public Twilio(ApexPages.StandardController stdController) {
        this.acct = (contact)stdController.getRecord();       
    }
    
    Public static Void sendfromtwilio (string Fromnumber,string text,string tonumber) {
        
        errorResponseWrapper erw;
        configuration_setting__c cstt=new configuration_setting__c();
        cstt = [select Name,AccountSid__c, Active__c,AuthToken__c,Bulk_SMS__c,Contact_Phone_Number__c,Lead_Phone_Number__c,TestPhone__c FROM configuration_setting__c where Name='Twilio' limit 1];
        String account = cstt.AccountSid__c;
        String token = cstt.AuthToken__c;
        HttpRequest req = new HttpRequest();
        req.setEndpoint('https://api.twilio.com/2010-04-01/Accounts/'+account+'/SMS/Messages.json');
        
        req.setMethod('POST');
        
        String VERSION  = '3.2.0';
        
        req.setHeader('X-Twilio-Client', 'salesforce-' + VERSION);
        
        req.setHeader('User-Agent', 'twilio-salesforce/' + VERSION);
        
        req.setHeader('Accept', 'application/json');
        
        req.setHeader('Accept-Charset', 'utf-8');
        
        req.setHeader('Authorization','Basic '+EncodingUtil.base64Encode(Blob.valueOf(account+':' +token)));
        
        req.setBody('To='+EncodingUtil.urlEncode(+tonumber,'UTF-8')+'&From='+EncodingUtil.urlEncode(+Fromnumber,'UTF-8')+'&Body='+text);
        
        Http http = new Http();        
        HTTPResponse res = http.send(req);  
        System.debug(res.getBody());
        system.debug(res.getStatusCode());
        if(res.getStatusCode()==201)
        {
            ApexPages.addmessage(new ApexPages.message(ApexPages.severity.Confirm,'SMS Sent Successfully'));
        } else{
            erw =(errorResponseWrapper)json.deserialize(res.getBody(),errorResponseWrapper.class);
            ApexPages.addmessage(new ApexPages.message(ApexPages.severity.ERROR,erw.message));
            System.debug('ERROR');
        }
    }
    public PageReference ok(){
        PageReference acctPage = new PageReference('/' +acct.Id);
        acctPage.setRedirect(true);
        return acctPage;
    }  
    public class errorResponseWrapper{
        String code;       
        String message;        
        String moreInfo;        
        String status;    
    }
}

Hi nihar,

Create the below HttpCalloutMock class first:

Apex Class
@isTest
global class Twilio_MockClass implements HttpCalloutMock {
    global HTTPResponse respond(HTTPRequest req) {
        HttpResponse res = new HttpResponse();
        res.setHeader('Content-Type', 'application/json');
        res.setBody('{"example":"test"}');
        res.setStatusCode(201);
        return res;
    }
}


Test Class:

@isTest
public class Twilio_Test {
    Public static testmethod void testTwilio(){
        Account acc = new Account(name = 'ABC');
        /// Add the remaining Mandatory fields which are required to create the Account Record
        insert acc;
        
        Contact con = new contact(LastName = 'ABC Contact',AccountId = acc.Id);
        /// Add the remaining Mandatory fields which are required to create the Contact Record
        insert con;
        
        configuration_setting__c cst = new configuration_setting__c();
        cst.Name = 'Twilio';
        cst.AccountSid__c = 'TestaccId';  /// Add the proper date here
        cst.AuthToken__c = 'TestAuth';   /// Add the proper date here
        insert cst;
        
        Test.setMock(HttpCalloutMock.class, new Twilio_MockClass());
        
        Twilio obj = new Twilio( new ApexPages.StandardController( con ) ); 
        obj.text1 = 'Test';
        obj.showmessage = true;
        obj.selectedvalue = 'Test';        
        obj.ok();
        
        Test.StartTest();
        
        Twilio.sendfromtwilio('1234567890','Test message','0987654321');
        
        Test.StopTest();

    }
}
