Newbie: Mock object for assert when field not exported

[protium]

Could have done something incorrect, but I imported the library, added a call
    
    
    privateAccess(SQLData)
    
    
    Run

before the assert and got the following back from the compiler
    
    
    D:\src\importutils.nim(23, 41) Warning: unknown magic 'PrivateAccess' might 
crash the compiler [UnknownMagic]
    D:\src\BuildPayrollYtds.nim(25, 16) template/generic instantiation of 
`privateAccess` from here
    D:\src\importutils.nim(23, 41) Warning: unknown magic 'PrivateAccess' might 
crash the compiler [UnknownMagic]
    D:\src\BuildPayrollYtds.nim(26, 44) Error: the field 'kind' is not 
accessible.
    
    
    Run
