QTP Questions - 5

1. Explain the concept of object repository & how QTP recognizes objects?

Object Repository: displays a tree of all objects in the current component or in the current action or entire test( depending on the object repository mode you selected).
we can view or modify the test object description of any test object in the repository or to add new objects to the repository.
Quicktest learns the default property values and determines in which test object class it fits. If it is not enough it adds assistive properties, one by one to the description until it has compiled the unique description. If no assistive properties are available, then it adds a special Ordinal identifier such as objects location on the page or in the source code.

2. How to handle dynamic objects in QTP?
QTP has a unique feature called Smart Object Identification/recognition. QTP generally identifies an object by matching its test object and run time object properties. QTP may fail to recognize the dynamic objects whose properties change during run time. Hence it has an option of enabling Smart Identification, wherein it can identify the objects even if their properties changes during run time.
Check this out-
If QuickTest is unable to find any object that matches the recorded object description, or if it finds more than one object that fits the description, then QuickTest ignores the recorded description, and uses the Smart Identification mechanism to try to identify the object.
While the Smart Identification mechanism is more complex, it is more flexible, and thus, if configured logically, a Smart Identification definition can probably help QuickTest identify an object, if it is present, even when the recorded description fails.
The Smart Identification mechanism uses two types of properties:
Base filter properties—the most fundamental properties of a particular test object class; those whose values cannot be changed without changing the essence of the original object. For example, if a Web link’s tag was changed from to any other value; you could no longer call it the same object. Optional filter properties—other properties that can help identify objects of a particular class as they are unlikely to change on a regular basis, but which can be ignored if they are no longer applicable.

3. What is a Run-Time Data Table? Where can I find and view this table?
In QTP, there is data table used, which is used at runtime.
-In QTP, select the option View->Data table.
-This is basically an excel file, which is stored in the folder of the test created, its name is Default.xls by default.

4. How does Parameterization and Data-Driving relate to each other in QTP?
To data drive we have to parameterize.i.e. We have to make the constant value as parameter, so that in each iteraration (cycle) it takes a value that is supplied in run-time datatable. Through parameterization only we can drive a transaction (action) with different sets of data. You know running the script with the same set of data several times is not suggestible, & it’s also of no use.

5. What is the difference between Call to Action and Copy Action.?
Call to Action : The changes made in Call to Action , will be reflected in the original action( from where the script is called).But where as in Copy Action , the changes made in the script ,will not effect the original script(Action)

6. Discuss QTP Environment.
QuickTest Pro environment using the graphical interface and Active Screen technologies - A testing process for creating test scripts, relating manual test requirements to automated verification features - Data driving to use several sets of data using one test script.

7. Explain the concept of how QTP identifies object.
During recording QTP looks at the object and stores it as test object. For each test object QT learns a set of default properties called mandatory properties, and look at the rest of the objects to check whether this properties are enough to uniquely identify the object. During test run, QT searches for the run time objects that match with the test object it learned while recording.

8. Differentiate the two Object Repository Types of QTP.
Object repository is used to store all the objects in the application being tested.2 types of object repository per action and shared. In shared repository only one centralized repository for all the tests. Where as in per action. For each test a separate per action repository is created.

9. What the differences are and best practical application of each.
Per Action: For Each Action, one Object Repository is created.
Shared : One Object Repository is used by entire application

10. Explain what the difference between Shared Repository and Per_Action Repository
Shared Repository: Entire application uses one Object Repository , that similar to Global GUI Map file in WinRunner
Per Action: For each Action ,one Object Repository is created, like GUI map file per test in WinRunner

11. Have you ever written a compiled module? If yes tell me about some of the functions that you wrote.
I used the functions for capturing the dynamic data during runtime. Function used for Capturing Desktop, browser and pages.
