Hi,
I am trying to create a test for a class that has if/else logic based on different lookup values for a field.  Below is a snippet of the code that I need to test.  I typcially would like to use Test Data Factory and testSetup when writing my unit tests.  I am trying to figure out the most efficient way to accomplish this.  

Should I create different student records with the different affliate lookup values in the Test Data Factory or is it more efficient to create one student record do a fetch a update with the different values in each test method?
 

if(student__c.affiliate__c == 'freshman') {
   // do stuff
}
else if(student__c.affiliate__c == 'sophomore') {
  // do stuff
}
else if (student__c.affiliate__c == 'junior') {
  // do stuff
}

Both student__c and affiliate__c are custom object.  There is a lookup r/ship b/n them.

 

I have a date field(Date) and a picklist field(Status).
I want the validation as, when the date field is passed by a month and the status is not renewed then the status should change to expired.

Thanks in advance!
