Devendra Hirulkar 3 write test class of below trigger
Hello
the following is my trigger
and i have no idea to how to write test class so please help me sir
trigger copypro on Subsc__c (after insert,after update)
{
//Id recordTypeId = [Select Id From RecordType Where DeveloperName = 'User Group Membership'].Id;
Id recordTypeId = Schema.SObjectType.Subsc__c.getRecordTypeInfosByName().get('User Group Membership').getRecordTypeId();
List<Subsc__c> subscList = new List<Subsc__c>();
for (Subsc__c s : Trigger.new){
if(s.RecordTypeId == recordTypeId)
subscList.add(s);
}
Map<ID, Account> Acc = new Map<ID, Account>(); //Making it a map instead of list for easier lookup
List<Id> listIds = new List<Id>();
set<ID>cObjectID = new set<ID>(); //Making a set of Product ID's
Map<ID, Account> updateMap = new Map<ID, Account>();
for (Subsc__c s : subscList)
{
listIds.add(s.Company_Name__c);
if(s.Product__c != null)
{
cObjectID.add(s.Product__c );//takes the Lookup Record & Add that ID's in cObjectID set
}
}
if(!cObjectID.isEmpty()){
Map<ID,Product2> cObjectMap = new Map<ID,Product2>([select Id,Name from Product2 where Id IN: cObjectID]);
Acc = new Map<Id, Account>([SELECT id, Product_Name__c,(SELECT ID,Product__c FROM Subscs__r) FROM Account WHERE ID IN :listIds]);
for(Subsc__c s : subscList)
{
if(cObjectMap.get(s.Product__c ).Name != Null)
{
// fill the country name on Opportunity with Country Name on Country_Object__c
String pro= cObjectMap.get(s.Product__c ).Name;
Account myacc = acc.get(s.Company_Name__c);
if(myacc != null){ //always check for nulls to avoid null pointer exceptions
myacc.Product_Name__c =pro;
updateMap.put(myacc.Id,myacc);
}
}
}
update updateMap.values();
}
}
please ans as soon possible
thanks

@isTest private class copyproTest { @isTest static void mytestMethod() { // Insert the Subsc__c object record with all mandatory fields and related records } }FYI - I strongly recommend you to go through apex test class Trail head module, which will be useful for you to understand apex test class https://developer.salesforce.com/trailhead/force_com_programmatic_beginner/apex_testing/apex_testing_intro

hi Devendra,try check the sobject variable or list for null check before insertion. This error commony occurs the variaiable you are trying to insert reurn null value. Do the check both in test class and trigger.
Subsc__c s = new Subsc__c(Name = 'ram',Company_Name__c=a.Id,Product__c='xyz'); test.startTest(); insert s;put a null check some thing like thisSubsc__c s = new Subsc__c(Name = 'ram',Company_Name__c=a.Id,Product__c='xyz'); if(s!=null){ test.startTest(); insert s; }
