Access Trigger.New value in Apex Test Class - triggers

Question

tl;dr - How do you make a test class wait until a specific trigger is done with its updates or inserts before continuing on with the test?
Background
I have a trigger that creates a new Portal_Content__c object whenever an Account object is created, and then associates both records with each other (see Account Trigger below).
I have also created a trigger on the Portal_Content__c object that fires when a record is deleted. When deleted, the trigger looks up the related Account record and deletes it (see Portal Content Trigger below).
My question is regarding my Portal Content Test Class (final code block below). When I run a DML insert on an Account record, the Account Trigger should populate the a.Portal_Content_Record__c field with the Portal Content record created in the Account Trigger. However, when I ran my system.debug() tests, it showed that the a.Portal_Content_Record__c field is null when the SOQL query is run. I have been able to bypass this by doing a search for the Portal Content record by matching name, but I would like to make the script more robust by searching by the exact ID.

How do I make the Portal Content Test Class wait until the Account Trigger has populated the a.Portal_Content_Record__c field before moving on with the test?

I have tested it in my Org. Please find my comments below.
According to your requirement, I have a trigger that creates a new Portal_Content__c object whenever an Account object is created, and then associates both records with each other (see Account Trigger below).
I see there is a relationship on the Account(Portal_Content_Record__c ) and the Portal Content (School_SFDC_ID__c). You are setting the Portal_Content_Record__c. but you need to link the School_SFDC_ID__c as well to fulfill your requirement. Please find the below code
trigger AccountHandler on Account (before insert, after insert, after update, after delete) {
List<Account> alist = Trigger.New;
List<Account> oldlist = Trigger.Old;
// Create the new Portal Content with the same name as Account if Account is record type College/University,
// then assign newly created Portal Content to Portal Content Record lookup field on new Account
if(Trigger.isBefore && Trigger.isInsert){
for(Account a : alist) {
if (a.RecordTypeId == '012i0000001Iy1H') {
Portal_Content__c p = new Portal_Content__c(
Name=a.Name,
RecordTypeId='012i0000001J1zZ',
School_SFDC_ID__c = a.id
);
insert p;
a.Portal_Content_Record__c = p.Id;
}
}
}
}
I see the only thing is delete is not getting covered in
PortalContentHandler because it doesn't meet with the condition for
List<Account> alist = [SELECT ID FROM Account WHERE Id =
:p.School_SFDC_ID__c]; Populate it when you are creating
Portal Content as describe in the above point.
Also, you need to change your test class as there is no data for Portal Content that you are trying to query. In the test class, you get the data what you created there only. The one which gets created by AccountHandler won't be part of your test class. Create the same data as you are creating in the trigger.
#isTest
public class PortalContentHandlerTest {
#isTest static void createThenDeletePortalContent(){
Account a = new
Account(Name='deletePortalTest',RecordTypeId__c='012i0000001Iy1H');
insert a;
Portal_Content__c p = new Portal_Content__c(
Name=a.Name,
RecordTypeId__c='012i0000001J1zZ',
School_SFDC_ID__c = a.id
);
insert p;
delete p;
}
}
