Map<id,class__C> claMap=new Map<id,class__C>([select NumberOfStudents__c,MaxSize__c from class__c]);
for(Student__c s:Trigger.new){
class__c cls=claMap.get(s.class__c);

cls.Name__c = 'Apex' ;
cls.MaxSize__c=1;
insert cls;
System.assertEquals(null,cls.NumberOfStudents__c );
Student__C std = new Student__C();
std.Last_Name__c='Tejpal';
std.class__C=cls.id;
insert std;
cls=[select MyCount__c from class__C where id=: cls.id];
System.assertEquals(1,cls.NumberOfStudents__c );
Student__C newstd = new Student__C();
newstd .Last_Name__c='Tejpal';
newstd .class__C=cls.id;
insert newstd ;
}
catch (Exception e){
System.assert(e.getMessage().contains('Can not add'));
