Ans:
QTP Professional provides the ability to merge existing assets from two object repositories into a single shared object repository using the Object Repository Merge Tool. This tool enables you to merge two shared object repositories (called the primary object repository and the secondary object repository), into a new third object repository, called the target object repository. Objects in the primary and secondary object repositories are automatically compared and then added to the target object repository according to preconfigurable rules that define how conflicts between objects are resolved.

After the merge process, the Object Repository Merge Tool provides a graphic presentation of the original objects in the primary and secondary object repositories, which remain unchanged, as well as the objects in the merged target object repository. Objects that had conflicts are highlighted. The conflict of each object that you select in the target object repository is described in detail. The Object Repository Merge Tool provides specific options that enable you to keep the suggested resolution for each conflict, or modify each conflict resolution individually, according to your requirements.

The Object Repository Merge Tool also enables you to merge objects from the local object repository of one or more actions into a shared object repository. For example, if QTP learned objects locally in a specific action in your test, you may want to add the objects to the shared object repository, so that they are available to all actions in different tests that use that object repository.

You open the Object Repository Merge Tool by choosing Tools > Object Repository Merge Tool in the Object Repository Manager.
How can we retrieve all objects located inside a Parent Object with QTP?
You can use the ChildObjects method to retrieve all objects located inside a specified parent object, or only those child objects that fit a certain programmatic description. To retrieve this subset of child objects, you first create a description object and add the set of properties and values that you want your child object collection to match using the Description object.

Note: You must use the Description object to create the programmatic description for the ChildObjects description argument. You cannot enter the programmatic description directly into the argument using the property:=value syntax.

Once you have "built" a description in your description object, use the following syntax to retrieve child objects that match the description:

Set MySubSet=TestObject.ChildObjects(MyDescription)
For example, the statements below instruct QTP to select all of the check boxes on the Itinerary Web page:
Set MyDescription = Description.Create()

Ans: You can export all of the objects contained in an action's local object repository to a new shared object repository in the file system or to a Quality Center project (if QTP is connected to Quality Center). This enables you to make the local objects accessible to other actions. You export local objects to a new shared object repository using the Object Repository window.

To export local objects to a new shared object repository:
1. Open the test that has the local objects you want to export.
2. Make sure that the Object Repository window is open.
3. In the Object Repository window, in the Action box, choose the action whose local objects you want to export.
4. Choose File > Export Local Objects. The Export Object Repository dialog box opens.

Note: If you are connected to Quality Center, the dialog box that opens is different from the standard file system dialog box. You can switch between the two dialog box versions by clicking the File System and Quality Center buttons in the Export Object Repository dialog box.

5. Select the location in which to save the file, specify the file or attachment name, and click Save or OK (depending on whether you are saving it to the file system or a Quality Center project).
The object repository is exported to the specified shared object repository (a file with a .tsr extension). You can now use the new shared object repository like any other shared object repository.

Tip: After you export the local objects, you can use the Object Repository Merge Tool to merge the shared object repository containing the exported objects with another shared object repository.

Ans: You can select an object in the application or Web site you are testing and highlight the test object in the object repository.

For example, to locate a Find a Flight image in a Web page, you can select it in your Web page using the pointing hand mechanism. After you select the Find a Flight image object from the selection dialog box and click OK, the parent hierarchy in the object repository tree expands and the Find a Flight image test object is highlighted.

To locate an object in the object repository:
1. Make sure your application or Web site is open to the correct window or page.

2. Click the Locate in Repository button or choose View > Locate in Repository. QTP is hidden, and the pointer changes into a pointing hand.

3. Use the pointing hand to click on the required object in your application or Web site.

Tip: You can hold the left CTRL key to change the window focus or perform operations such as right-clicking or moving the pointer over an object to display a context menu. If the window containing the object you want to click is partially hidden by another window, you can also hold the pointing hand over the partially hidden window for a few seconds until the window comes into the foreground and you can point and click on the object you want. Additionally, if the window containing the object you want to select is minimized, you can display it by holding the left CTRL key, right-clicking the application in the Windows task bar, and choosing Restore from the context menu.

If the location you clicked is associated with more than one object, the Select an Object dialog box opens.

4. Select the object you want to locate in the object repository and click OK. The selected object is highlighted in the object repository.

Tip: If the relevant object repository is not open or the object cannot be found, the object is not highlighted. In the Object Repository Manager, if more than one shared object repository is open, and QTP cannot locate the selected object in the active object repository, you can choose whether to look for the object in all of the currently open object repositories.
