+@param aUptPc is the TBool specifying the Program Counter parameter to pass to the UTrace API
+@param aUptContext is the TBool specifying the Context parameter to pass to the UTrace API
+@param aSizeOfUptData is the size in bytes of the Data field being used in the relevant API calls containing a data field, passed as a TInt
+@param aTestPrimary is the boolean specifying whether to test the Primary filter setting (ETrue does test the primary filter, EFalse doesn't)
+@param aTestSecondary is the boolean specifying whether to test the Secondary filter setting (ETrue does test the secondary filter, EFalse doesn't)
+@param aTestUTraceULoggerMatch is the boolean specifying whether the filter settings in ULogger match the filter parameters assigned to the Trace points (ETrue matches, EFalse doesn't match)
+@param aTestMinimumExecution is the boolean specifying whether to test the minimum execution time for the API call
+							ETrue = minimum execution time, i.e. cached trace
+							EFalse = typical execution time, i.e. uncached trace
+@return ApiTestResult is the API Call test result struct object returned to the calling program, which contains all the test results from the relevent test run
