Here's my original code and test... but I still have 0 coverage

Trigger:

trigger Bulk_CallLogs on Student_Call_Log__c (after delete, after update) {

// 1. Loop through Trigger.new & throw the relevent info in a list (either list of leads, list of lead id's, etc)
// 2. Use the list to query related objects to populate another list
// 3. Loop through the 2nd list to create a map of LeadID to related object
// 4. Loop again through Trigger.new to add the related info to Lead using the map from #3


list<Student_Call_Log__c> list_thelogs = new list<Student_Call_Log__c>(); // list contains all of the logs being processed

// Step 1
set <id> list_relatedstudents_temp = new set <id> ();

for (Student_Call_Log__c log :list_thelogs) {
list_relatedstudents_temp.add(log.related_student__c);
}

list<Student__c> list_relatedstudents = ([select id from Student__c where id IN :list_relatedstudents_temp]);

// Step 2
