QTP Interview Questions III

1. Explain the check points in QTP? - A checkpoint verifies that expected information is displayed in an Application while the test is running. You can add eight types of checkpoints to your test for standard web objects using QTP. A page checkpoint checks the characteristics of an Application. A text checkpoint checks that a text string is displayed in the appropriate place on an Application. An object checkpoint (Standard) checks the values of an object on an Application. An image checkpoint checks the values of an image on an Application. A table checkpoint checks information within a table on a Application. An Accessibilityy checkpoint checks the web page for Section 508 compliance. An XML checkpoint checks the contents of individual XML data files or XML documents that are part of your Web application. A database checkpoint checks the contents of databases accessed by your web site
2. In how many ways we can add check points to an application using QTP? - We can add checkpoints while recording the application or we can add after recording is completed using Active screen (Note : To perform the second one The Active screen must be enabled while recording).
3. How does QTP identify objects in the application? - QTP identifies the object in the application by Logical Name and Class.
4. What is Parameterizing Tests? - When you test your application, you may want to check how it performs the same operations with multiple sets of data. For example, suppose you want to check how your application responds to ten separate sets of data. You could record ten separate tests, each with its own set of data. Alternatively, you can create a parameterized test that runs ten times: each time the test runs, it uses a different set of data.
5. What is test object model in QTP? - The test object model is a large set of object types or classes that Quick Test uses to represent the objects in your application. Each test object class has a list of properties that can uniquely identify objects of that class and a set of relevant methods that Quick Test can record for it. A test object is an object that Quick Test creates in the test or component to represent the actual object in your application. Quick Test stores information about the object that will help it identify and check the object during the run session.
6. What is Object Spy in QTP? - Using the Object Spy, you can view the properties of any object in an open application. You use the Object Spy pointer to point to an object. The Object Spy displays the selected object’s hierarchy tree and its properties and values in the Properties tab of the Object Spy dialog box.
7. What is the Diff between Image check-point and Bit map Check point? - Image checkpoints enable you to check the properties of a Web image. You can check an area of a Web page or application as a bitmap. While creating a test or component, you specify the area you want to check by selecting an object. You can check an entire object or any area within an object. Quick Test captures the specified object as a bitmap, and inserts a checkpoint in the test or component. You can also choose to save only the selected area of the object with your test or component in order to save disk Space. For example, suppose you have a Web site that can display a map of a city the user specifies. The map has control keys for zooming. You can record the new map that is displayed after one click on the control key that zooms in the map. Using the bitmap checkpoint, you can check that the map zooms in correctly. You can create bitmap checkpoints for all supported testing environments (as long as the appropriate add-ins are loaded). Note: The results of bitmap checkpoints may be affected by factors such as operating system, screen resolution, and color settings.
8. How many ways we can parameterize data in QTP? - There are four types of parameters: Test, action or component parameters enable you to use values passed from your test or component, or values from other actions in your test. Data Table parameters enable you to create a data-driven test (or action) that runs several times using the data you supply. In each repetition, or iteration, Quick Test uses a different value from the Data Table. Environment variable parameters enable you to use variable values from other sources during the run session. These may be values you supply, or values that Quick Test generates for you based on conditions and options you choose. Random number parameters enable you to insert random numbers as values in your test or component. For example, to check how your application handles small and large ticket orders, you can have Quick Test generate a random number and insert it in a number of tickets edit field.
9. How do u do batch testing in WR & is it possible to do in QTP, if so explain? - Batch Testing in WR is nothing but running the whole test set by selecting Run Test set from the Execution Grid. The same is possible with QTP also. If our test cases are automated then by selecting Run Test set all the test scripts can be executed. In this process the Scripts get executed one by one by keeping all the remaining scripts in Waiting mode.
10. If I give some thousand tests to execute in 2 days what do u do? - Adhoc testing is done. It Covers the least basic functionalities to verify that the system is working fine.
