Recovery Scenarios

While running a test in QTP there are certain Unexpected events, errors, and application crashes which can distort your run session and distort results.

This can result in the test run getting suspended until the occurred event has been corrected.

User may have to again begin the complete test run which can be tedious if the test script is very long or there are more than two or more tests called in the current run.

A Recovery Scenario helps the user as it indicates QTP with regards to the corrective action needed to be taken in case of the unwanted event occurred during the test run.

Example is you can instruct QTP to detect a Printer out of paper message and recover the run session by clicking the OK button to close the message and continue the test or component. pgorantla.blogspot.com

Recovery Scenarios

Recovery Scenarios are generally called by QTP on occurrence of any error during the test run.

Conditions where the user can predict any unexpected event, it is recommended to use optional steps or if conditions in the script.

Recovery scenarios should be used only for unpredictable events, or events that you cannot synchronize with a specific step in your test or component.


Recovery Scenarios

User has to be careful while adding recovery scenarios as it gets activated only after a step returns an error, which can potentially occurs several steps after the one that actually caused the error.

Alternatively, checking for trigger events after every step, may slow performance.


Recovery Scenarios

A Recovery scenario wizard helps the user in defining recovery scenarios, save them and also associate these to the corresponding tests. The path is Tools>Recovery Scenario Manager> New scenario.

A recovery scenario wizard consists of the following; Trigger events Recovery Operation Post-Recovery Test Run Option Name Finish


Recovery Scenarios


Recovery Scenarios

• Trigger Events: Indicates for which event the user needs to add an recovery scenario.

• Consists of the following events:

– Pop-up Window: A window pops up in an opened application during the test run.

– Object State: The property values of an object in your application match specified values. You can specify property values for each object in the hierarchy.

– Test run error: A step in your test does not run successfully.

– Application crash: An open application fails during the test run.

QTP detects a pop-up window and identifies it according to the window title and textual content.

In this the user has the option to set Window title and/or contents within the Window making it convenient to QTP in calling the corresponding scenario.

The user will have to initially capture the screen user the object spy for identification by QTP.


Recovery Scenarios

Note: It is preferable that the user selects regular expressions option as it will help if any contents in the captured text changes. Also if either Window title or text contains check box are not selected then QTP will not check for the corresponding option.

QTP detects a specific test object state and identifies it according to its property values and the property values of all its ancestors.

The user will have to identify the object using the Object spy and the corresponding object or parent properties get captured.

Further the user has the option to add or remove certain properties that shall be used by QTP for identification during scenario call.


Note: An object is identified only by its property values, and not by its class.

Recovery Scenarios

QTP detects a run error and identifies it by a failed return value from a method. This option consists of a list in the drop down box as shown below.

User selects any one of the error conditions and the corresponding description for that error occurs in the description box.


Recovery Scenarios

QTP detects an application crash and identifies it according to a predefined list of applications

When the user selects this trigger event, he gets an list of applications from which he will have to select the applications that might cause a error. Each time this application causes the error the scenario is called.


Recovery Scenarios

In this screen the user defines the kind of recovery operation that QTP needs to perform once the event has occurred.

The different operations are;

Key or mouse operation: The following operations can be performed Clicks Default button or Enter key. Clicks Cancel button or Esc key. Click any button on the corresponding screen which the user can

highlight by using the Spy available user can provide a combination of keys which the QTP will operate on

the key board.

Close application: The processes declared by the user while defining the Application crash trigger event shall be identified by QTP and closed once this event occurs.

Function Call Screen: User has a option wherein he can call a function stored in the Library depending upon the type of trigger event and the Select Function option.

Restarting Microsoft Windows: This option will lead to sudden termination of your script run and will close all the applications. pgorantla.blogspot.com

Recovery Scenarios

The user then gets the option to decide what QTP will perform once the recovery operation is implied. It will operate one of the following below given conditions;

Repeat current step and continue

Proceed to next step

Proceed to next iteration

Restart Current test run

Stop the Current Run


Recovery Scenarios

Once the user has completed creating the scenario he will have the option to name the scenario and description.

User shall get all the conditions associated with the corresponding scenario and will have an option; Add the scenario to the Current test Add scenario to default test settings.


Recovery Scenarios

The user can view the properties set to the created scenario.

The user can also edit the created scenario, copy the current to an new test and also delete the scenario.


Recovery Scenarios

The user can add a scenario to the test by Test>Settings and in the dialog box select Recovery tab.

The user clicks on the “+”symbol and gets an new box from where he can import anew recovery scenario andinsert it to the current test.

Also depending upon the importance of the scenario the user can either enable or disable the current scenario through the check box

The user can also prioritize the scenarios depending upon their importance in the test using the arrow keys available.


Recovery Scenarios

User can utilize the Recovery object to control the recovery mechanism programmatically during the run session.

User can also use the Recovery object's method to force QTP to check for triggers after a specific step in the run session.

User can define a recovery scenario that looks for and closes specified open processes when an object's properties have a certain state. This state shows the object's property values as they would be if the problematic processes were open.

User can instruct QTP to activate the recovery mechanism if the checkpoint fails so that QTP will check for and close any problematic open processes and then try to perform the checkpoint again.


Recovery Scenarios

Method/Property Description

Activate Method Explicitly activates the recovery scenario mechanism at a specific point in the run.

GetScenarioName Method Retrieves the name and source file of a recovery scenario, according to the specified position in the list of recovery scenarios associated with the test or component.

GetScenarioPosition Method

Returns the position of a recovery scenario in the list of recovery scenarios associated with the test or component, according to the specified name and source file.

GetScenarioStatus Method Returns the status of a recovery scenario (True = enabled or False = disabled), according to the specified position in the list of recovery scenarios associated with the test or component.

SetScenarioStatus Method Enables or disables the specified recovery scenario, according to its position in the list of recovery scenarios associated with the test or component.

Count Property Returns the number of recovery scenarios associated with the current test or component.

Enabled Property Recovery default property. Retrieves or sets the status of the recovery scenario mechanism for the current test or component.

Q & A….

Recovery Scenarios

Recovery scenario helps the user to avoid any interference during the test run.

During the Test run if any error occurs then QTP calls any one of the recovery scenario assigned to the test.

A single test can have more than one Recovery Scenario.

It consists of Trigger event, Recovery operation, Post-Recovery Test run options.

Recovery Object Methods are available to call and activate the various scenarios.
