I have a helper method in my code called canQueryObject, and that method returns a boolean. I have some code that calls the method via the following line of code:
if(!myObjectHelper.canQueryObject(Schema.SObjectType.<<objectType>>)) ...
I'd like to test some scenarios where the scenario is false. Is there a way I can use Mock or Stubs in a unit-test to set canQueryObject to false?

I typically use a fairly simple pattern and don't bring in a framework. It would look something like the following:
public virtual with sharing class MyObjectHelper
static MyObjectHelper instance = new MyObjectHelper();
@TestVisible static void setMock(MyObjectHelper mock) instance = mock;
public static Boolean canQueryObject(SObjectType sObjectType)
return instance.getCanQueryObject(sObjectType);
// the two method names cannot match or you will get a compile fail
protected virtual Boolean getCanQueryObject(SObjectType sObjectType)
return sObjectType.getDescribe().isQueryable();
Then in your test, you can have a mock return always true or always false, as you wish.
@IsTest
class MyObjectHelperTests
class HelperMock extends MyObjectHelper
Boolean isQueryable = true;
protected override Boolean getCanQueryObject(SObjectType sObjectType)
return isQueryable;
@IsTest static void testCannotQuery()
HelperMock mock = new HelperMock();
mock.isQueryable = false;
MyObjectHelper.setMock(mock);
Test.startTest();
Boolean canQuery = MyObjectHelper.canQueryObject(...);
Test.stopTest();
system.assertEquals(false, canQuery, 'Some informative message');
