Odd/Incorrect DDT Code Example in Documentation

[Mike359]

Hi, 

I have been learning how to script 'Data Driven Tests' in TestComplete.

The Documentation here : https://support.smartbear.com/testcomplete/docs/testing-with/data-driven/drivers.html

Has some javascript examples which I tried out. But it did not seem to work too well. (You had to choose the Driver function each time)

ie 

var RecNo;
// Posts data to the log (helper routine)
function ProcessData()
{
  var Fldr, i;  
  Fldr = Log.CreateFolder("Record: " + aqConvert.VarToStr(RecNo));
  Log.PushLogFolder(Fldr);  
  for(i = 0; i < DDT.CurrentDriver.ColumnCount; i++)
    Log.Message(DDT.CurrentDriver.ColumnName(i) + ": " + aqConvert.VarToStr(DDT.CurrentDriver.Value(i))); 
  Log.PopLogFolder();
  RecNo = RecNo + 1;
}
  
// Creates the driver (main routine)
function TestDriver()
{
  var Driver;  
  // Creates the driver
  // If you connect to an Excel 2007 sheet, use the following method call:
  // Driver = DDT.ExcelDriver("C:\\MyFile.xlsx", "Sheet1", true);
  Driver = DDT.ExcelDriver("C:\\MyFile.xls", "Sheet1");
  
  // Iterates through records
  RecNo = 0;
  while (! Driver.EOF() )
  {
    ProcessData(); // Processes data
    Driver.Next(); // Goes to the next record
  }  
  // Closes the driver
  DDT.CloseDriver(Driver.Name);
}

After examining the code I found it was not quite correct (Its like someone messed with it just to try to get it to run)

I have corrected the code in the example to get it to working as I think it was intended.

// Posts data to the log (helper routine)
function ProcessData(RecNo)
{
var Fldr, i;
Fldr = Log.CreateFolder("Record: " + aqConvert.VarToStr(RecNo));
Log.PushLogFolder(Fldr);
for(i = 0; i < DDT.CurrentDriver.ColumnCount; i++)

  {
   Log.Message(DDT.CurrentDriver.ColumnName(i) + ": " + aqConvert.VarToStr(DDT.CurrentDriver.Value(i)));
   }

Log.PopLogFolder();
}

// Creates the driver (main routine)
function TestDriver()
{
var Driver, RecNo;
// Creates the driver
// If you connect to an Excel 2007 sheet, use the following method call:
// Driver = DDT.ExcelDriver("C:\\MyFile.xlsx", "Sheet1", true);
Driver = DDT.ExcelDriver("C:\\MyFile.xls", "Sheet1");
// Iterates through records
RecNo = 0;
while (! Driver.EOF() )
   {
   ProcessData(RecNo); // Processes data
   Driver.Next(); // Goes to the next record
   RecNo = RecNo + 1;
   }
// Closes the driver
DDT.CloseDriver(Driver.Name);
}

I hope it's of use to others 🙂 as it had me baffled for a while.

(NB. Don't forget to press on the '>' symbol, next to each record output in the log, to see the data extracted from your spreadsheet.)

@Mike359 , thank you for the idea. I've passed this to the Documentation team!
