WaitProperty Method

Applies to TestComplete 15.64, last modified on May 16, 2024


Use the WaitProperty method to pause the test execution until the specified object property achieves the specified value or until the specified timeout elapses.


TestObj.WaitProperty(PropertyName, PropertyValue, WaitTime)

TestObj A variable, parameter or expression that specifies a reference to one of the objects listed in the Applies To section
PropertyName [in]    Required    String    
PropertyValue [in]    Required    Variant    
WaitTime [in]    Optional    Integer Default value: -1   
Result Boolean

Applies To

All processes, windows, controls and onscreen objects.

View Mode

This method is available in the Object Browser panel and in other panels and dialogs in both Basic and Advanced view modes.


The method has the following parameters:


The name of the desired property.


The property value to wait for before continuing the test execution.

You can enter the item’s index (from 0) or its caption.

The caption can contain wildcards or regular expressions:

  • The asterisk (*) wildcard corresponds to a string of any length (including an empty string).

  • The question mark (?) wildcard corresponds to any single character (including none).

  • To specify more complicated sought-for patterns for the caption, use regular expressions in the following format: regexp:<pattern>. For example, regexp:gr[ae]y.

    Use standard TestComplete (non-native) syntax to specify regular expressions. The property does not support native regular expression syntax, that is, the syntax provided by scripting languages.


    • The caption can be case-sensitive or case-insensitive depending on the Use case-sensitive parameters project setting. The regular expression patterns are always case-insensitive. For example, "regexp:gr[ae]y" will match both "gray" and "GRAY".

    • Patterns search for partial matches. For example, regexp:notepad matches both "notepad" and "notepad++". To search for an exact match, use the ^ and $ anchors, for example "regexp:^notepad$".

    For detailed information on regular expression syntax, see Regular Expressions Syntax .


The number of milliseconds to wait for the specified property value. If WaitTime is 0, the method does not wait and returns immediately. If WaitTime is -1, the waiting time is specified by the Auto-wait timeout project property.

Note: If you are testing an Open Application, the WaitTime parameter is required. In case of a non-Open Application, the WaitTime parameter is optional and has the default value 0.

Result Value

If the property achieves the specified value within the timeout, the method returns True. Otherwise, if the timeout elapses before the property achieves the specified value, the method returns False.

Also, False if the object does not have the specified property.


  • The WaitProperty method does not support indexed properties (that is, properties that require parameters). To wait until an indexed property becomes equal to a specific value, you can use a loop like the following:

    JavaScript, JScript

    while (statusBarObj.wText(0) != "Ready")


    while (statusBarObj.wText(0) != "Ready"):


    While statusBarObj.wText(0) <> "Ready"
      aqUtils.Delay 100


    while statusBarObj.wText[0] <> 'Ready' do

    C++Script, C#Script

    while (statusBarObj["wText"](0) != "Ready")


The following example demonstrates how to use the WaitProperty method in scripts:

JavaScript, JScript

var btn = Sys.Process("MyApp").Window("TMainFrm","MyApplication *").Child(2);
if (btn.WaitProperty("Enabled", true, 2000))
  // Button is enabled
  // Button is disabled


btn = Sys.Process("MyApp").Window("TMainFrm","MyApplication *").Child(2)
if btn.WaitProperty("Enabled", True, 2000):
   # Button is enabled
   # Button is disabled


Set btn = Sys.Process("MyApp").Window("TMainFrm","MyApplication *").Child(2)
If btn.WaitProperty("Enabled", True, 2000) Then
  ' Button is enabled
  ' Button is disabled
End If


  btn : OleVariant;
  btn := Sys.Process('MyApp').Window('TMainFrm','MyApplication *').Child(2);
  if btn.WaitProperty('Enabled', true, 2000) then
    // Button is enabled
    // Button is disabled

C++Script, C#Script

var btn = Sys["Process"]("MyApp")["Window"]("TMainFrm","MyApplication *")["Child"](2);
if (btn["WaitProperty"]("Enabled", true, 2000))
  // Button is enabled
  // Button is disabled
