Devendra Hirulkar 3 how to write test class of this trigger
hellow friends,
i want test class of the below trigger i am new in the apex word so please tell me the test class
trigger CopyRolltoStudent1 on class__c (before insert,before update) //You want it on update too, right?
{
Map<ID, Student__c> parentroll = new Map<ID, Student__c>(); //Making it a map instead of list for easier lookup
List<Id> listIds = new List<Id>();
for (class__c childObj : Trigger.new)
{
listIds.add(childObj.student__c);
}
//Populate the map. Also make sure you select the field you want to update, Rollno
//The child relationship is more likely called Classes__r (not Class__r) but check
//You only need to select the child classes a if you are going to do something for example checking whether the Classes in the trigger is the latest
parentroll = new Map<Id, Student__c>([SELECT id, Roll_No__c,(SELECT ID, Roll_No__c FROM Class__r) FROM Student__c WHERE ID IN :listIds]);
for (class__c cl : Trigger.new)
{
Student__c myParentroll = parentroll.get(cl.student__c);
myParentroll.Roll_No__c = Decimal.valueOf(cl.Roll_No__c);
}
update parentroll.values();
}
this is my trigger
thanks
