Description

Use the OCRTable object to access the table that TestComplete recognizes on the screen by using optical character recognition (OCR). To get the object in tests, use the OCR.Recognize(SearchArea).AsTable or OCR.Recognize(SearchArea).DetectTable properties.

Example

The example below uses the DetectTable property to recognize tabular data on a web page and posts the recognized data to the test log:

JavaScript, JScript

function Main()
{
  // Navigate to the tested web page
  var url = "https://www.w3schools.com/html/tryit.asp?filename=tryhtml_table_border";
  Browsers.Item("chrome").Run(url);

  // Get the page area containing the table
  var page = Sys.Browser("chrome").Page("*");
  var gridArea = page.FindChild("idStr", "iframeresult", 10);

  if (gridArea != null)
  {
    // Specify whether the table has a header
    var hasHeader = true;
    // Specify the preferable search area
    var searchPref = spNone;
    // Recognize the table content
    var table = OCR.Recognize(gridArea).DetectTable(searchPref, hasHeader);

    // Call the routine that posts table data to the test log
    PrintTable(table);

  }
  else
    Log.Warning("Cannot obtain the search area.");
}

function PrintTable(aTable)
{
  if (aTable != null)
  {
    Log.AppendFolder("Table contents:");
    for (var i = 0; i < aTable.RowCount; i++)
    {
      for (var j = 0; j < aTable.ColumnCount; j++)
      {
        Log.Message(aTable.Cell(i, j).Text);
      }
    }
    Log.PopLogFolder();
  }
}

Python

  # Navigate to the test web page
  url = "https://www.w3schools.com/html/tryit.asp?filename=tryhtml_table_border"
  Browsers.Item["chrome"].Run(url)

  page = Sys.Browser("chrome").Page("*")
  gridArea = page.FindChild("idStr", "iframeresult", 10)

  if (gridArea != None):
    # Specify whether the table has a header
    hasHeader = True
    # Specify the preferable search area
    searchPref = spNone
    # Recognize the table contents
    table = OCR.Recognize(gridArea).DetectTable[searchPref, hasHeader]

    # Call the routine that post table data to the test log
    PrintTable(table)

  else:
    Log.Warning("Cannot obtain the search area.")
