If I load multiple HttpCalloutMock's when settings up a test:

Test.setMock(HttpCalloutMock.class, MockFactory.create());

And I am using a MultiRequestMock implementation:

public without sharing class MultiRequestMock implements HttpCalloutMock 

 Map<String, HttpCalloutMock> requests;

 public MultiRequestMock(Map<String, HttpCalloutMock> requests) 
 this.requests = requests;
 

 public HTTPResponse respond(HTTPRequest req) 

 HttpCalloutMock mock = requests.get(req.getEndpoint());

 if (mock != null) 
 return mock.respond(req);
 

 throw new CustomException('Mock for end point not found: ' + req.getEndpoint());
 

 public void addRequestMock(String url, HttpCalloutMock mock) 
 requests.put(url, mock);
 

And I don't persist the results from the callout.

Is there anyway to check that eachany of the HttpCalloutMock have been used?

Declare a variable in your mock class, and set its value in the respond method. if that variable is true at the end of your test , it means mock was used and callout was done.

global class CalloutMock1 implements HttpCalloutMock 

 global boolean isCalled = false;
 global HTTPResponse respond(HTTPRequest req) 
 isCalled = true;
 // Create a fake response.
 // Set response values, and 
 // return response.
 

Test Class:

CalloutMock1 cm1= new CalloutMock1();
Test.setMock(HttpCalloutMock.class, cm1);

//Call your code.


System.assert(cm1.isCalled); 

Edit :Based on your updated code:

public without sharing class MultiRequestMock implements HttpCalloutMock 

 public Map<String, HttpCalloutMock> requests;
 public Set<String> usedEndpoints = new Set<String>();

 public MultiRequestMock(Map<String, HttpCalloutMock> requests) 
 this.requests = requests;
 

 public HTTPResponse respond(HTTPRequest req) 

 HttpCalloutMock mock = requests.get(req.getEndpoint());
 usedEndpoints.add(req.getEndpoint());

 if (mock != null) 
 return mock.respond(req);
 

 throw new CustomException('Mock for end point not found: ' + req.getEndpoint());
 

 public void addRequestMock(String url, HttpCalloutMock mock) 
 requests.put(url, mock);
 

Test Class :

MultiRequestMock mm = new MultiRequestMock (new Map<String, HttpCalloutMock>());
mm.addRequestMock();//

//Do your callouts

//Then Assert here

System.assert(mm.usedEndpoints.contains('Your endpoint') , 'Your Endpoint not called'); //Your endpoint called
System.assert(mm.usedEndpoints.size() == mm.requests.size() , 'Not all mocks were consumed');
