Hi Folks,

I require some assistance creating a test class for a trigger that I wrote. Any help would be greatly appreciated:
 

trigger SCHParseReceivedEmail on BMCServiceDesk__IncidentHistory__c (after insert){
    for (BMCServiceDesk__IncidentHistory__c action : trigger.new){    

            if(action.BMCServiceDesk__FKIncident__c != null){
                BMCServiceDesk__Incident__c ticket = [SELECT id, Customer_Reference_Number__c,BMCServiceDesk__Incident__c.Relationship_Name__c FROM BMCServiceDesk__Incident__c WHERE Id = :action.BMCServiceDesk__FKIncident__c];
                
                if(action.BMCServiceDesk__actionId__c == 'Email Received') {
                                    if(ticket.Relationship_Name__c == 'Random Customer Name') {
                        ticket.Customer_Reference_Number__c = action.BMCServiceDesk__description__c.substringBetween('##');
                            update Ticket;                
                }
           }    
    }

  }
}

Here are some required linkages between the objects being tested.

Incident History relies on an Incident to exist.  It receives emails and creates an incident history record.  I believe all I need to do in my test class is create an incident and an incident history record linked and verify that my trigger updated with the correct chracters located in between the ## delimiters in my substring.  I am having some issues getting a test class created and i think that I am probably overthinking things...

Here is what I have for my test class - currently getting an error Error: Compile Error: unexpected token: 'static' at line 16 column 5
