I acquired the Apex trigger below and I've been trying to create a test class for it but I keep getting 0 coverage. Would anyone have any tips on how to create this?
 

Trigger AccountHistoryTracker on Account (after update) {

final List<Schema.FieldSetMember> trackedFields = 
    SObjectType.Account.FieldSets.HistoryTracking.getFields();

if (trackedFields.isEmpty()) return;

final List<AccountHistoryTracking__c> fieldChanges = 
    new List<AccountHistoryTracking__c>();

if(!trigger.isUpdate)
    return;

for (Account newAccount : trigger.new) {

    final Account oldAccount = trigger.oldmap.get(newAccount.Id);

    for (Schema.FieldSetMember fsm : trackedFields) {

        String fieldName  = fsm.getFieldPath();
        String fieldLabel = fsm.getLabel();
     System.debug( fieldname + fieldLabel );

        if (newAccount.get(fieldName) == oldAccount.get(fieldName))
            continue;

        String oldValue = String.valueOf(oldAccount.get(fieldName));
        String newValue = String.valueOf(newAccount.get(fieldName));

        if (oldValue != null && oldValue.length()>255) 
            oldValue = oldValue.substring(0,255);

        if (newValue != null && newValue.length()>255) 
            newValue = newValue.substring(0,255); 

        final AccountHistoryTracking__c accountHistory = 
            new AccountHistoryTracking__c();

        accountHistory.apiName__c   = fieldName;
        accountHistory.Account__c      = newAccount.id;
        accountHistory.OldValue__c  = oldValue;
        accountHistory.NewValue__c  = newValue;

        fieldChanges.add(accountHistory);
    }
}

if (!fieldChanges.isEmpty()) {
    insert fieldChanges;
}
}

 

Hello,

I created a simple checkbox field on a custom object that "checks" if another DateTime field is TODAY. It works great... however there is a discrepancy between the Details page, View and Reports. The Details page Checkbox field "checks" at 12am however, the View and Reports only checks after 1am. Does anyone know of a bug or why in one place the field works and nother the field won't.
 

Hello,

I need to be able to highlight a row within a view to indicate that the case is due today. Please let me know how I can achieve that.
 

I'd like to create a flow that our HR department can use for onboarding a new hire that creates a user account and configures settings such as assigning a managed package, setting a role, setting a profile, etc.

I haven't found a lot of information on this... is it even possible?
