Hello, 
I have apex class and apex test_Class. my coverage is on 57%. Please can someone help me.

My Apex Class:

public class show_opp {

@AuraEnabled
    public static void updateEntityInfos(string entityWrapperList, String year,Decimal Amount, Decimal GrandC,Decimal NewBus, String Zone,Decimal AutresC) {       
        Decimal Amounts = Amount;
        string zonee= Zone;
        ID currentiduser;
        List <user> currentiduserlist=[Select id  from user  where id =: Label.userassign   limit 1]; 
        if (currentiduserlist.size() > 0)
        {
          currentiduser = currentiduserlist[0].id;
        } 
         List<String> zones = new list<String> { 'A1' , 'A2' , 'A3', 'A4'};

        If (entityWrapperList != null){
            id  recordtypeid;
            List <recordtype> RecordtypeOpp= [Select id  from recordtype  where id =: Label.ObjectifGlobalOpp  limit 1];
            if (RecordtypeOpp.size() > 0)
            {
            recordtypeid = RecordtypeOpp[0].id;
            }                         
           List<EntityWrapperClass> ObjList = new List<EntityWrapperClass>();
           ObjList =(List<EntityWrapperClass>)System.JSON.deserialize(entityWrapperList,List<EntityWrapperClass>.class);
          
           List<Opportunity> opportunityList = new List<Opportunity>();  
           List<Opportunity> opportunityListup = new List<Opportunity>(); 
            for(EntityWrapperClass obj:ObjList ){
                 opportunity o=new opportunity();
                 string zonename= obj.name;
                if (zones.contains(zonename))
                {
                   o.Zone__C=obj.name;
                   o.ObjZoneEuro__c    = obj.turnover;
                   o.Objectif_Global_Zone__c=obj.globalObjective;     

                }
                else 
                {
                    o.Agence__c=obj.name;
                   o.Zone__C=zonee;
                   o.Objectif_Global_Agence__c=obj.globalObjective;
                }
                  
               o.Global_New_Business__c=obj.newBusiness; 
               o.Global_Major_Account__c=obj.b2b; 
               o.Global_Other__c=obj.others; 
                o.Objectif_CA__c=Amounts;
               o.Id= obj.opportunityId;
               o.ObjectifYear__c    = year;
               o.OwnerId    = currentiduser;
               o.CloseDate = Date.newInstance(Integer.valueOf(year), 12, 31);
               o.StageName = 'Qualification';
              opportunityList.add(o);
            }
        for (Opportunity o:opportunityList)
        {
        }
        upsert opportunityList;
        }
        
      {          
        id recordtypeidg;
        
        List <recordtype> RecordtypeOppg= [Select id  from recordtype  where id =: Label.ObjectifGlobalOpp  limit 1];
        if (RecordtypeOppg.size() > 0)
        {
          recordtypeidg = RecordtypeOppg[0].id;
        }          
        
        List<Opportunity> OpportunityGlobal = [Select id, Objectif_CA__c, Global_New_Business__c,Global_Major_Account__c, Global_Other__c   from Opportunity  where recordtypeid =: recordtypeidg and ObjectifYear__c =:  year ORDER BY Createddate DESC LIMIT 1];
        system.debug('OpportunityGlobal  ' +OpportunityGlobal );
        if (OpportunityGlobal.size()>0){
             Decimal NewBusiness = NewBus;
            Decimal GrandCs = GrandC;
            Decimal AutresCs = AutresC;
           
            OpportunityGlobal[0].CloseDate = Date.newInstance(Integer.valueOf(year), 12, 31);
            OpportunityGlobal[0].Objectif_CA__c = Amounts;
            OpportunityGlobal[0].Global_New_Business__c = NewBusiness;            
            OpportunityGlobal[0].Global_Major_Account__c = GrandCs;         
            OpportunityGlobal[0].Global_Other__c = AutresCs;             
            OpportunityGlobal[0].ObjectifYear__c = year;             
            OpportunityGlobal[0].OwnerId = currentiduser;
         
            OpportunityGlobal[0].recordtypeid = recordtypeidg;  
            Database.upsert(OpportunityGlobal);                
        }
    }          
        
        }        
}

My Apex Test_Class:
@IsTest
public class show_opp_Test {
@isTest
    // run the the class test
    static void showoppTest() {
        
        // Test data setup
        String result;

        
        Test.startTest();
         LNCO5_ShowObjectifAnnuelSopexa.updateEntityInfos ('[{"b2b":10,"globalObjective":21,"name":"A1","newBusiness":"6","opportunityId":"0065E00000CDKWwQAP","others":80,"turnover":14910000},{"b2b":20,"globalObjective":22,"name":"A2","newBusiness":10,"opportunityId":"0065E00000CDKWvQAP","others":"8","turnover":15620000},{"b2b":3,"globalObjective":12,"name":"A3","newBusiness":4,"opportunityId":"0065E00000CDKWuQAP","others":80,"turnover":8520000},{"b2b":3,"globalObjective":14,"name":"A4","newBusiness":60,"opportunityId":"0065E00000CDKWtQAP","others":"10","turnover":9940000}]','2019', 7000, 20 ,19, 'A1', 35);
      
        Test.stopTest();
        
        
     //   System.assertEquals('SUCCESS' , result);
        
    }
