I need to improve my code coverage please can any one help me out

Trigger:

 trigger Rfleet_UpdateforecastAllCountry on Country_DCVF_Volume__c (after insert,after update,after delete) {
string TempYear;
Integer TempMonth;
Integer FinalVolume=0;
Integer FinalForecast=0;

if(trigger.isinsert||trigger.isupdate ){

    if(Dcvfcount.IKAM_Data__c!=null){
        Ikamids.add(Dcvfcount.IKAM_Data__c);
        Accountids.add(Dcvfcount.Parent_Account__c);
    }
}
}

 }

          updateIkam.Countries_forecast__c=FinalForecast ;
     }
 }
update Ikamupdate;
}

My test class:

@isTest
private class Rfleet_UpdateforecastAllCountry_Test {
static testmethod void Rfleet_UpdateforecastAllCountry_TestMethod(){

Country_DCVF_Volume__c ContryDCVF = new Country_DCVF_Volume__c(
CurrencyIsoCode='India', 
Country__c='Algeria',
Parent_Account__c='001m000000Kg3ys',
Region__c='France',
Insertion_date__c=system.today(), 
KAM__c='Ganz Bruno',
Delivered_volume__c=1.5,
IKAM_Data__c='a3em0000000DCsq'
);
insert ContryDCVF;      
    IKAM_Data__c ikam= new IKAM_Data__c(
    Annual_global_deliveries_commitment__c=09.0,
    Annual_deliveries_target__c=72,
    Account__c='Bosch',
    IKAM_Year__c=2015
);
insert ikam;

}
}

Best Answer

CurrencyIsoCode must be a three-letter code that identifies a country's currency, like USD stands for United States Dollars, or JPY for Japanese Yen.

Indian Rupee is INR.
