Hi Ram,

Please add below cde part before you call the ''doPost()'' method,
Lead objLead = new Lead(FirstName = 'test ', LastName ='record ', 
                        Phone = '9999999999', Email = 'test.record@xyz.com', OwnerId = lstUser[0].Id,
                        Company = 'xyz' , Street = 'lane 1,lane 2,', City = 'pune', 
                        State = 'Maharastra', PostalCode = '411014', Country = 'India');
    
        insert objLead;

Hi Ram,
Please check your Duplicate Rule. I tested a duplicate rule with the matching rule of 'Standard Lead Matching Rule'.
If you are using any custom matching rule, please create test data accordinglly.
Here is the test code,
@isTest public static void testdoPost(){  
        profile objProfile = [select id from profile where name='Standard User'];   
        
        user user2 = new user(LastName = 'Test_User1_do',Email = 'testdo.user@user.com',Alias = 'Tcode do',Username = 'testdo.user@user.com',CommunityNickname = 'testdo',LocaleSidKey = 'en_US',TimeZoneSidKey = 'GMT',ProfileID = objProfile.Id,LanguageLocaleKey = 'en_US',EmailEncodingKey = 'UTF-8');
        insert user2;
