InvokeApplication Statement

Abstract

The InvokeApplication statement is used to start the application. It doesn’t matter which technology build application you are trying to run and open. The statement in itself falls under the category of utility statements and not utility objects. Remember there is a difference between utility statements and utility objects.

Before we dig down deep into the usage let’s quickly visit some general questions.

In the interview usually, you might be questioned in different ways like:

1. How to get your windows application invoked in the test run?
2. Can you associate the parameters to the InvokeApplication statement?
3. What are the objects and parameters of InvokeApplication statement?
4. is InvokeApplication is an object or statement?
5. What is the difference between systemutil.run and invokeapplication?
   

Discussion

In most of the testing scenarios we try opening the application via script. In this script we use InvokeApplication statement for invoking the targeted application along with any parameters. Officially, this statement can invoke any executable application.

But there is difference between InvokeApplication and SystemUtil. You must use the InvokeApplication statement only when you are targeting the some old versions of the application which is why it is quite recommended that it is to be used primarily for backward compatibility. 

Points to note here:

1. You can add this statement manually in the Expert View.
2. It is to be used primarily for backward compatibility.
3. If the invokeapplication statement fails to open the application, a “False” value is returned.
