determine file name of downloaded file

I did say I'd let you know how it went...

 

I now have a script unit that can do all the required work to do this.  Too much code to put it here, but basically, I have two project variables.  DownloadsFolder and WorkingFolder.

 

I change my browser to always download to the Project Variable folder (c:\TC\Downloads)

 

There is a method that can clear folder contents, some copy/move functions and GetFile methods.

 

Before I download, I delete the contents of both folders.  I can then use aqFileSystem.FindFiles and return the first one I find - there is handling if I don't find anything in the form of returning null. The calling function needs to check for nulls.  This function can take a search pattern, so I don't need to know the exact filename.  This caters for those downloads that have their names changing because they were downloaded at a later time.  Now, the piece that I had to put in to cater to the fact that there is no connect between clicking the save button (using UIAObjects) and the file download completing.  I have a function that waits for the file to exist.  Its more reliable and faster than a set delay. :smileytongue::

 

 

function WaitFileExistsSearch(folderPath, searchPattern, timeout)
{
  if(StringIsNullOrEmpty(folderPath))
  {
    Log.Error("No folder path specified");
    return false;
  }
  
//DefaultValue is a script unit I wrote that has methods for converting null or undefined values to a default value.  If it's not null, the current value is returned
  searchPattern = DefaultValue.GetString(searchPattern,"*.*");
  timeout = DefaultValue.GetInt(timeout,Options.Run.Timeout);
  var startTime = GetTickCount();
  var fileExists = false;
  
  LogMessageVerbose("Waiting for file to exists","FilePath : " + folderPath + "\nSearch Pattern : " + searchPattern);
  
  var waitTime = GetTickCount() - startTime;
  while(waitTime < timeout && fileExists==false)
  {
    if(GetFile(folderPath,searchPattern,true)!=null)
    {
      fileExists=true;   
    }   
    else
    {
      aqUtils.Delay(100,"Checking File Existence (" + folderPath + ")");
    }
    waitTime = GetTickCount() - startTime;
  }
  
  if(!fileExists)
  {  
    Log.Error("File did not exists within the specified time period","FilePath : " + folderPath + "\nSearch Pattern : " + searchPattern);
  }
  else
  {
    LogMessageVerbose("File Exists", "Wait Time : " + waitTime + "ms");
  }
  
  return fileExists
  
}

Once I have the file in the downloads folder, I can move the file to the working folder :

 

aqFileSystem.MoveFile(DownloadFolder,WorkingFolder,!overwriteOnCollision);

 

Now I can reliably use my datadriver, since I control where my files are and it doesn't matter that the file name changes each time, because I can rename it to what I want before DataDrivers start using it - or I can pass the file path to the DataDriver
