Trigger Event Handling in QTP

Select Trigger Event Screen In QTP Automation Testing

The Select Trigger Event screen enables you to define the event type that triggers the recovery scenario, and the way in which QuickTest recognizes the event. 

Select a type of trigger and click Next. The next screen displayed in the wizard depends on which of the following trigger types you select:

Pop-up window. QuickTest detects a pop-up window and identifies it according to the window title and textual content. For example, a message box may open during a run session, indicating that the printer is out of paper. QuickTest can detect this window and activate a defined recovery scenario to continue the run session.
Select this option and click Next to continue to the Specify Pop-up Window Conditions Screen.


Object state. QuickTest detects a specific test object state and identifies it according to its property values and the property values of all its ancestors. Note that an object is identified only by its property values, and not by its class.
For example, a specific button in a dialog box may be disabled when a specific process is open. QuickTest can detect the object property state of the button that occurs when this problematic process is open and activate a defined recovery scenario to close the process and continue the run session.
Select this option and click Next to continue to the Select Object Screen.


Test run error. QuickTest detects a run error and identifies it by a failed return value from a method. For example, QuickTest may not be able to identify a menu item specified in the method argument, due to the fact that the menu item is not available at a specific point during the run session. QuickTest can detect this run error and activate a defined recovery scenario to continue the run session.
Select this option and click Next to continue to the Select Test Run Error Screen.


Application crash. QuickTest detects an application crash and identifies it according to a predefined list of applications. For example, a secondary application may crash when a certain step is performed in the run session. You want to be sure that the run session does not fail because of this crash, which may indicate a different problem with your application. QuickTest can detect this application crash and activate a defined recovery scenario to continue the run session.
Select this option and click Next to continue to the Recovery Operations Screen.
Notes:


The set of recovery operations is performed for each occurrence of the trigger event criteria. For example, suppose you define a specific object state, and two objects match this state, the set of recovery operations is performed two times, once for each object that matches the specified state.


The recovery mechanism does not handle triggers that occur in the last step of a test or component. If you need to recover from an unexpected event or error that may occur in the last step of a test or component, you can do this by adding an extra step to the end of your test or component.
