Description
When you call a method of an object, TestComplete pauses the script execution until the execution of the called method is over (that is, the script is paused until the method returns). Using the CallObjectMethodAsync
method you can call application methods without pausing the script. This is useful if the method displays a modal window or dialog and you need to simulate user actions in this dialog (see Testing Modal Windows for more information).
You can also use this method to obtain a property’s value asynchronously (that is, you can use the method to perform asynchrounous calls to the property’s get
method).
Declaration
Runner.CallObjectMethodAsync(Obj, MethodName, Param1, Param2, ..., ParamN)
Obj | [in] | Required | The object whose method will be called | |
MethodName | [in] | Required | String | |
Param1 | [in] | Optional | Variant | |
Param2 | [in] | Optional | Variant | ... |
ParamN | [in] | Optional | Variant | |
Result | A CallObjectMethodAsyncResult object |
Applies To
The method is applied to the following object:
Parameters
The method has the following parameters:
Obj
Specifies the object whose method will be called.
MethodName
The name of the desired object method or property.
Param1, Param2, ... ParamN
Specifies the method parameters (if any). If you obtain the value of an indexed property, these parameters specify the index values.
Result Value
CallObjectMethodAsync
returns the CallObjectMethodAsyncResult
object that contains methods and properties allowing you to pause the script execution until the called method returns and providing access to method results.
Remarks
CallObjectMethodAsync
was added to simplify testing of modal windows and dialog boxes displayed by script routines or by methods that reside in Open Applications. See Testing Modal Windows for complete information.
It is not recommended to use this method to perform asynchronous calls to methods provided by TestComplete (that is, to methods that are provided by TestComplete but not by the application under test).
This method cannot be used in script extensions. For more information on objects that you can use in script extensions, see Objects Available to Script Extensions.
This method cannot be used to call methods of custom objects you create in your tests.
Example
The following example demonstrates how you can use the Runner.CallObjectMethodAsync
method to display a modal window and perform testing actions over it.
JavaScript, JScript
{
var TestedApp, Form, ModalForm, Result;
// Launches the tested application
TestedApp = TestedApps.ModalSamples;
TestedApp.Run();
Form = Aliases.SampleApp.Form;
// Calls the method that displays a modal form
Result = Runner.CallObjectMethodAsync(Form, "ShowModal");
// Performs actions over the modal form
ModalForm = Aliases.SampleApp.ModalForm;
…
// Closes the modal form
ModalForm.Close();
// Waits for the method completion
Result.WaitForCompletion(2000);
…
TestedApp.Close();
}
Python
def Test():
# Launches the tested application
TestedApp = TestedApps.ModalSamples
TestedApp.Run()
Form = Aliases.SampleApp.Form
# Calls the method that displays a modal form
Result = Runner.CallObjectMethodAsync(Form, "ShowModal")
# Performs actions over the modal form
ModalForm = Aliases.SampleApp.ModalForm
# ...
# Closes the modal form
ModalForm.Close()
# Waits for the method completion
Result.WaitForCompletion(2000)
# ...
TestedApp.Close()
VBScript
Dim TestedApp, Form, ModalForm, Result
' Launches the tested application
Set TestedApp = TestedApps.ModalSamples
TestedApp.Run
Set Form = Aliases.SampleApp.Form
' Calls the method that displays a modal form
Set Result = Runner.CallObjectMethodAsync(Form, "ShowModal")
' Performs actions over the modal form
Set ModalForm = Aliases.SampleApp.ModalForm
…
' Closes the modal form
ModalForm.Close
' Waits for the method completion
Result.WaitForCompletion(2000)
…
TestedApp.Close
End Sub
DelphiScript
var TestedApp, Form, ModalForm, Result;
begin
// Launches the tested application
TestedApp := TestedApps.ModalSamples;
TestedApp.Run;
Form := Aliases.SampleApp.Form;
// Calls the method that displays a modal form
Result := Runner.CallObjectMethodAsync(Form, 'ShowModal');
// Performs actions over the modal form
ModalForm := Aliases.SampleApp.ModalForm;
…
// Closes the modal form
ModalForm.Close();
// Waits for the method completion
Result.WaitForCompletion(2000);
…
TestedApp.Close();
end;
C++Script, C#Script
{
var TestedApp, Form, ModalForm, Result;
// Launches the tested application
TestedApp = TestedApps["ModalSamples"];
TestedApp["Run"]();
Form = Aliases["SampleApp"]["Form"];
// Calls the method that displays a modal form
Result = Runner["CallObjectMethodAsync"](Form, "ShowModal");
// Performs actions over the modal form
ModalForm = Aliases["SampleApp"]["ModalForm"];
…
// Closes the modal form
ModalForm["Close"]();
// Waits for the method completion
Result["WaitForCompletion"](2000);
…
TestedApp["Close"]();
}
