In your tests, you may need to check whether the expected text is rendered on screen, and, depending on the check result, to perform various actions (for example, to simulate user actions or to post a custom message to the test log). You can do this in the following way:

Recognize the rendered text in the needed screen area by using the OCR.Recognize method.
Get the recognized text by using the OCR.Recognize.FullText property.
Check whether the obtained text contains the expected substring. To do this, you can use various operations that compare string values. For example, the aqString.Find method. See Working With Strings.
Depending on the check results, perform the needed actions.

Note: To verify the text contents against a pattern and to post a success/fail message to the test log, use OCR checkpoints. See Verify Text Contents.

In scripts

The code below contains the CheckTextContents routine that gets an onscreen object and a string and verifies that the object’s text includes the string. As the third parameter, the routine takes a Boolean value that specifies whether the check is case-sensitive or case-insensitive. To get the onscreen object’s text, the routine uses the OCR.Recognize.FullText property. To verify that the rendered text contains the string, the routine uses the aqString.Find method. If the expected substring is present, the routine returns True; otherwise, it returns False.

JavaScript, JScript

function CheckTextContents(anObject, aSubstring, caseSensitive)
{
  // Recognize the text contents of the specified onscreen object
  var text = OCR.Recognize(anObject).FullText;
  // Search for the occurrence of the specified substring in the recognized text
  return (aqString.Find(text, aSubstring, 0, caseSensitive) > -1)
}

function Main()
{
  var textToCheck = "substring";
  // Get the onscreen object whose text will be checked
  var form = Sys.WaitProcess("MyApp").WaitWindow("Window", "*", -1, 3000);
  …
  // Check the text
  if (CheckTextContents(form, textToCheck, false))
    Log.Message("The substring '" + textToCheck + "' has been found.");
  else
    Log.Warning("The substring " + textToCheck + " has not been found.");
  …

}

Python

def CheckTextContents(anObject, aSubstring, caseSensitive=False):
  # Recognize the text contents of the specified onscreen object
  text = OCR.Recognize(anObject).FullText
  # Searches for the occurrence of the specified substring in the recognized text
  return (aqString.Find(text, aSubstring, 0 , caseSensitive) > -1)


def Main():
  textToCheck = "substring"
  # Get the onscreen object whose text will be checked
  form = Sys.WaitProcess("MyApp").WaitWindow("Window", "*", -1, 3000)
  if (form.Exists):
    # Check the text
    if (CheckTextContents(form, textToCheck, False)):
     Log.Message("The substring '" + aqConvert.VarToStr(textToCheck) + "' has been found.")
    else:
      Log.Warning("The " + aqConvert.VarToStr(textToCheck) + " substring was not found.")

VBScript

Function CheckTextContents(anObject, aSubstring, caseSensitive)
  ' Recognize the text contents of the specified onscreen object
  text = OCR.Recognize(anObject).FullText
  ' Search for the occurrence of the specified substring in the recognized text
  CheckTextContents = (aqString.Find(text, aSubstring, 0 , caseSensitive) > -1)
End Function

Sub Main
  textToCheck = "substring"
  ' Get the onscreen object whose text will be checked
  Set form = Sys.WaitProcess("MyApp").WaitWindow("Window", "*", -1, 3000)
  …
  ' Check the text
  If CheckTextContents(form, textToCheck, false) Then
    Log.Message("The substring '" & textToCheck & "' has been found.")
  Else
    Log.Warning("The substring '" & textToCheck & "' has not been found.")
  End If
  …
End Sub

DelphiScript

function CheckTextContents(anObject : OleVariant, aSubstring : String, caseSensitive : boolean = false);
var text;
begin
  // Recognize the text contents of the specified onscreen object
  text := OCR.Recognize(anObject).FullText;
  // Search for the occurrence of the specified substring in the recognized text
  result : = (aqString.Find(text, aSubstring, 0, caseSensitive) > -1);
end;

function Main();
var textToCheck, form;
begin
    textToCheck := 'substring';
  // Get the onscreen object whose text will be checked
  form := Sys.WaitProcess('MyApp').WaitWindow('Window', '*', -1, 3000);
  …
  // Check the text
  if CheckTextContents(form, textToCheck, false) then
    Log.Message('The substring ''' + aqConvert.VarToStr(textToCheck) + ''' has been found.')
  else
    Log.Warning('The substring ''' + aqConvert.VarToStr(textToCheck) + ''' has not been found.');
  …
end;

C++Script, C#Script

function CheckTextContents(anObject, aSubstring, caseSensitive)
{
  // Recognize the text contents of the specified onscreen object
  var text = OCR["Recognize"](anObject)["FullText"];
  // Search for the occurrence of the specified substring in the recognized text
  return (aqString["Find"](text, aSubstring, 0, caseSensitive) > -1);
}

function Main()
{
  var textToCheck = "substring";
  // Get the onscreen object whose text will be checked
  var form = Sys["WaitProcess"]("MyApp")["WaitWindow"]("Window", "*", -1, 3000);
  …
  // Check the text
  if (CheckTextContents(form, textToCheck, false))
    Log["Message"]("The substring '" + textToCheck + "' has been found.");
  else
    Log["Warning"]("The substring '" + textToCheck + "' has not been found.");
  …

}

The Main routine in the example above shows how to call the CheckTextContents routine to verify that the main form of the tested application renders the expected substring. Depending on the result, it posts the appropriate message to the test log.

In keyword tests

Copy the CheckTextContents function code from the example above to a script unit in your test project in TestComplete.
Call this function from your keyword test. To do this, you can use the Run Code Snippet or Run Script Routine operation.
Get the function results. Depending on them perform needed actions. To learn how to get the routine results, see Checking Operation Result.
