Test class returning error Invalid field Name even though the field name is correct - help!

Hello, 

I am trying to create a test class for a recently created trigger, and I am getting an error that Mobile__c is "Invalid field Name for SObject Task". 

The thing is that I have this field (Mobile__c) as an activity custom field and reference it in my trigger without issue. 

Here is the trigger: 

Trigger TaskBefore on Task(before insert, before update){
    Map<Id, List<Task>> whoIds = new Map<Id, List<Task>>{};
    For (Task t : trigger.new)
        If(t.WhoId != null){
            List<Task> tasks = whoIds.get(t.WhoId); //this should be t.WhoId (not task.WhoId)
            If (tasks == null){
            tasks = new List<Task>{};
            whoIds.put(t.WhoId, tasks);
        }
        tasks.add(t);
    }
    For (Lead ld : [Select Id, Name, MobilePhone from Lead where Id in :whoIDs.keySet()])
        For(Task t : whoIds.get(ld.id))
            t.Mobile__c = ld.MobilePhone;
    For(Contact con : [Select Id, Name, MobilePhone from Contact where Id in :whoIds.keySet()])
        For(Task t : whoIds.get(con.id))
            t.Mobile__c = con.MobilePhone;
}

And here is my tet class:

 

@isTest
private class TaskBeforeTestClass {
    static testMethod void validateTaskBefore() {
        Task t = new Task (Name='Validation Test Task', Mobile__c = '');
        System.debug('Mobile before insterting new task: ' + t.Mobile__c);
// Insert task
insert t;
//Retrieve the new task
t = [ SELECT Mobile__c FROM Task WHERE Id =:b.Id];
System.debug('Mobile after trigger fired: ' + t.Mobile__c);
// Test that the trigger correctly updated the mobile phone
System.assertNotEquals('', t.Mobile__c);
}
}

My approach here is that I am trying to validate that Mobile__c is BLANK before the trigger fires and not blank after. 

I am pretty new to apex coding, so I really appreciate the help!

Thanks, 

John

    Hi John,

    Name field does not exist with Task object, so you will have to remove it from the test class while creating Task record. Use subject field instead.

     

    @isTest
    private class TaskBeforeTestClass {
        static testMethod void validateTaskBefore() {
            Task t = new Task (Subject='Validation Test Task', Mobile__c = '');
            System.debug('Mobile before insterting new task: ' + t.Mobile__c);
    // Insert task
    insert t;
    //Retrieve the new task
    t = [ SELECT Mobile__c FROM Task WHERE Id =:b.Id];
    System.debug('Mobile after trigger fired: ' + t.Mobile__c);
    // Test that the trigger correctly updated the mobile phone
    System.assertNotEquals('', t.Mobile__c);
    }
    }
