Clap Master Create CaseHistory entry through Apex
I'm creating cases in a test class to do unit testing, and I need to have the test cases also have some case history items. When you edit a case through the UI, we have 'Status' as a tracked field, so any cahnges are tracked in the CaseHistory table. When I cahnge the 'Status' programatically however, through Apex, it does not create an extry in the CaseHistory table.
Does anyone know how to accomplish this?
1. Per the SFDC http://www.salesforce.com/us/developer/docs/object_reference/index.htm xxxHistory objects are readOnly. You can't do DML inserts on these objects
2. And, yes, testmethods won't create xxxHistory objects either. Note: http://success.salesforce.com/ideaView?id=08730000000h6RwAAI
3. A way around this is to abstract your CaseHistory access using a CaseHistoryWrapper class. If test.isRunningtest() is false, then fetch CaseHistory using SOQL and populate the wrapper by copying from the actual CaseHistory.oldValue, newvalue, .. fields into public properties in your wrapper; If test.isRunningtest() is true, don't execute any SOQL and instead directly populate your public properties in the wrapper with known test data.
