I've used a pretty awesome trigger template, and I've tested that the trigger behavior is working as expected (knock on wood). I took it from a peer's blog (http://blog.deadlypenguin.com/blog/2012/02/13/classifying-triggers-in-salesforce/) and it's working well.

The logic of the trigger automatically inserts child records (Vendor_Scorecard__c) lookup to the parent (Service_Request__c) if Service Request is in Status of 'In Review'.

I'm having trouble on the test class, I need to query for the existence of child VSCs and assert that they inserted properly, but i'm not sure how. I also have another issue from a pre-existing trigger (too many SOQL) but i'm not sure why it hits the limit.

This tests a lot of triggers...and some are poorly written so I can't set test data over 5 records or it fails (that's another problem, not for today). How would I query for the created Vendor_Scorecard__c for each of the srf's in the list?

static testMethod void addVendorIdTest() {   
	
	//Create test Task Order
	Task_Order__c t = new Task_Order__c(Name = 'Test Task Order');
	Insert t;	       
	
	//Create test Account
	Account a = new Account(Name = 'Test', Task_Order__c = t.Id, Lin__c = '9999');
	Insert a;
   
	//Create test Contact
	Contact c = new Contact(LastName = 'Test', AccountId = a.Id, Vendor_Id__c = '123ABC');
	Insert c; 
	
	//Create test Service Request BULK
	List <Service_Request__c> srfTestList = new List <Service_Request__c>();
	  for (integer i=0; i<5; i++) {
		Service_Request__c sr = new Service_Request__c(
			Task_Order__c = t.Id, 
			Vendor_Id__c = '123ABC', 
			Status__c = 'New'
		);
		  srfTestList.add(sr);
	  }
			
	  insert srfTestList;
	  
	  test.startTest();  
	  for(Service_Request__c srf: srfTestList) {
		srf.Status__c = 'In Review';
		update srf;  	
	  }
	  test.stopTest();
				
	List <Service_Request__c> insertedSRFs = [Select Vendor_Name__c, Id FROM Service_Request__c WHERE Id IN: srfTestList];
	
	String testVendor = [SELECT Vendor_Name__c FROM Service_Request__c WHERE Id = :srfTestList LIMIT 1].Vendor_Name__c;
	
	for (Service_Request__c s: insertedSRFs){
	  System.assertEquals(c.Id, testVendor);
	}
	
}

This is the method (classified trigger) that creates the Vendor_Scorecard__c objects for each srf in srfList. Ignore the excessive comments, that's for me...

public void doAwesomeness() {
	
	if (isUpdate) {
		
	  set<Id> objIds = new Set<Id>();
	  
	  for (Service_Request__c srf: newObjs) {
		if (
			oldMap.get(srf.ID) != null &&
			oldMap.get(srf.ID).Status__c != srf.Status__c &&
			srf.Status__c == 'In Review'
		) {
		  //Set for unique IDs for records that pass conditionals above 
			objIds.add(srf.Id);
		}
	  }
	  
	  //Maybe don't need where Status statement, since it's done above?
	  //List is to house records that have passed conditions above		  
	  List <Service_Request__c> srfList =
		[SELECT Status__c, Id, Vendor_Name__c
		 FROM Service_Request__c
		 WHERE Status__c = 'In Review'
		 AND Id IN: objIds];
	  
	  //List for update of VSCs added, for each of the srf in the list above
	  List<Vendor_Scorecard__c> vscList = new List<Vendor_Scorecard__c>();

	  //for records in list, iterate through and use values from those records to create new child VSCs
	  for (Service_Request__c srf: srfList){
		Vendor_Scorecard__c vsc = new Vendor_Scorecard__c (
			Service_Request__c = srf.Id, 
			Vendor__c = srf.Vendor_Name__c,
			RecordTypeId = '012800000007dww');
		vscList.add(vsc);
	  }
	  if (!vscList.isEmpty()) {
		try {
		  insert vscList;
		} catch (DmlException e) {}
	  }
	//End Routing Boolean, return necessary?     
	} else {
	  return;
	}
}
