Error Recovery

Recover Scenario:
Unexpected events, errors, and application crashes during a run session can disrupt your run session and distort results.
This is a problem particularly when running tests or components unattended—the test or component is suspended until you perform the operation needed to recover.
A recovery scenario consists of the following:
1.Trigger Event
2. Recovery Operation(s)
3. Post Recovery Test Run option
Deciding When to use Recovery Scenarios
• If we can predict that a certain event may happen at a specific point in your test or component.
• For e.g., say overwrite file message.
Defining Recovery Scenario
• The Recovery Scenario Manager dialog box enables to create recovery scenarios and save them in recovery files.
• We can create recovery scenarios using the Recovery Scenario Wizard, which leads through the process of defining each of the stages of the recovery scenario.
• We then save the recovery scenarios in a recovery file, and associate them with specific tests or components.

Understanding the Recovery Scenario Wizard

• Defining the trigger event that interrupts the run session
• Specifying the recovery operation(s) required to continue
• Choosing a post-recovery test run operation
• Specifying a name and description for the recovery scenario
• Specifying whether to associate the recovery scenario to the current test and/or to all new tests

Managing Recovery Scenarios

Managing Recovery Scenarios
Recovery Scenario Manager enables us to manage existing scenarios by:

Viewing Recovery Scenario Properties
Modifying Recovery Scenarios
Deleting Recovery Scenarios
Copying Recovery Scenarios between
Recovery Scenario files

Setting Recovery Scenarios List for the Tests
Adding Recovery Scenarios to the tests

Viewing Recovery Scenario Properties
Setting Recovery Scenario Priorities
Enabling and Disabling Recovery Scenarios
Setting Default Recovery Scenario Settings for All New Tests


Programmatically Controlling the Recovery Mechanism

We can use the Recovery object to control the recovery mechanism programmatically during the run session. For example:
 
Enable or disable the entire recovery mechanism or specific recovery scenarios for certain parts of a run session.
Retrieve status information about specific recovery scenarios
Explicitly activate the recovery mechanism at a certain point in the run session
By default, QuickTest checks for recovery triggers when an error is returned during the run session.
We can use the Recovery object’s Activate method to force QuickTest to check for triggers after a specific step in the run session

Programmatically Controlling the Recovery Mechanism

Recovery Object


Represents the Recovery tab of the Test Settings or Business Component Settings dialog box, which enables you to configure which recovery scenarios to associate with a test or business component.
Methods
Add Adds the specified recovery scenario to the specified position.
Find The position of the specified recovery scenario.
MoveToPos Changes the order of the recovery scenarios by moving a recovery scenario from its current position to a specified position.
Remove Removes the recovery scenario that is located in the specified position.
RemoveAll Removes all recovery scenarios from the Recovery collection.
SetActivationMode Sets the activation mode for all the recovery scenarios associated with the test or component.
SetAsDefault Sets the current list of recovery scenarios as the default recovery scenarios for all new tests or business components.
