// This class runs the test preprocessor
// It uses AliTestShuttle to simulate a full Shuttle process

// The input data is created in the functions
//   CreateDCSAliasMap() creates input that would in the same way come from DCS
//   ReadDCSAliasMap() reads from a file
//   CreateInputFilesMap() creates a list of local files, that can be accessed by the shuttle

void ADTestPreprocessor()
{
  // load library
  gSystem->Load("libTestShuttle.so");

   // create AliTestShuttle instance
  // The parameters are run, startTime, endTime

  // TODO(1)
  //
  // The shuttle can read DCS data, if the preprocessor should be tested to process DCS data,
  // some fake data has to be created.
  //
  // The "fake" input data can be taken using either (a) or (b):
  // (a) data from a file: Use ReadDCSAliasMap()
  //     the format of the file is explained in ReadDCSAliasMap()
  //     To use it uncomment the following line:
  //
  //TMap* dcsAliasMap = ReadDCSAliasMap();
  //
  // (b) generated in this macro: Use CreateDCSAliasMap() and its documentation
  //     To use it uncomment the following line:
  //
  TMap* dcsAliasMap = CreateDCSAliasMap();

  // now give the alias map to the shuttle
  shuttle->SetDCSInput(dcsAliasMap);

  // TODO(2)
  //
  // The shuttle can also process files that originate from DCS, DAQ and HLT.
  // To test it, we provide some local files and locations where these would be found when
  // the online machinery would be there.
  // In real life this functions would be produces by the sub-detectors
  // calibration programs in DCS, DAQ or HLT. These files can then be retrieved using the Shuttle.
  //
  // Files are added with the function AliTestShuttle::AddInputFile. The syntax is:
  // AddInputFile(<system>, <detector>, <id>, <source>, <local-file>)
  // In this example we add a file originating from the GDC with the id PEDESTALS
  // Three files originating from different LDCs but with the same id are also added
  // Note that the test preprocessor name is TPC. The name of the detector's preprocessor must follow
  // the "online" naming convention ALICE-INT-2003-039.
//  shuttle->AddInputFile(AliShuttleInterface::kDAQ, "TPC", "PEDESTALS", "GDC0", "file1.root");
//  shuttle->AddInputFile(AliShuttleInterface::kDAQ, "TPC", "DRIFTVELOCITY", "LDC0", "file2a.root");
//  shuttle->AddInputFile(AliShuttleInterface::kDAQ, "TPC", "DRIFTVELOCITY", "LDC1", "file2b.root");
//  shuttle->AddInputFile(AliShuttleInterface::kDAQ, "TPC", "DRIFTVELOCITY", "LDC2", "file2c.root");

//
  // TODO(3)
  //
  // The shuttle can read run type stored in the DAQ logbook.
  // To test it, we must provide the run type manually. They will be retrieved in the preprocessor
  // using GetRunType function.
  shuttle->SetInputRunType("PHYSICS");

  // TODO(4)
  //
  // The shuttle can read run parameters stored in the DAQ run logbook.
  // To test it, we must provide the run parameters manually. They will be retrieved in the preprocessor
  // using GetRunParameter function.

  // TODO(5)
  //
  // This is for preprocessor that require data from HLT.
  // Since HLT may be switched off, the preprocessor should first query the Run logbook where
  // the HLT status is stored. SHUTTLE implements a shortcut function (GetHLTStatus) that returns
  // a bool directly. 1 = HLT ON, 0 = HLT OFF
  //
