How to Cover the Wrapper Class Test Method in Salesforce

To Cover the Wrapper Class test method in FieldAx,

Code –

public with sharing class sno_in_table{

public list<wrap> getRecords()    {
integer sno=1;
list<wrap>emps=new list<wrap>();
list<employee__c>emp_records=[select name,phone__c from employee__c];

            for(employee__c em:emp_records){

emps.add(new wrap(sno,em));
sno++;

             }
return emps;
}

//wrapper class

public class wrap{
public integer sno{get;set;}
public employee__c emp{get;set;}

public wrap(integer sn, employee__c e){
emp=e;
sno=sn;
}

}

public static testmethod void m1(){
sno_in_table sno=new sno_in_table();
sno.getrecords();
}

}

Solution: –

Integer int=56;

employee__c emp = new employee__c();

// if possible insert fields in this

sno_in_table.wrap cmp = new sno_in_table.wrap(int,emp);
