QTP Interview Questions Answers

Question 1 : Explain the check points in QTP?

Answer 1 : 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

Question 2 : What does it mean when a check point is in red color? what do u do?

Answer 2 : A red color indicates failure. Here we analyze the cause for failure whether it is a Script Issue or Environment Issue or a Application issue.

Question 3 : If I give some thousand tests to execute in 2 days what do u do?

Answer 3 : Adhoc testing is done. It Covers the least basic functionalities to verify that the system is working fine.

Question 4 : How do u do batch testing in WR & is it possible to do in QTP, if so explain?

Answer 4 : 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.

Question 5 : What is the file extension of the code file & object repository file in QTP?

Answer 5 : Code file extension is.vbs and object repository is.tsr

Question 6 : Give me an example where you have used a COM interface in your QTP project?

Answer 6 : com interface appears in the scenario of front end and back end. for eg:if you r using oracle as back end and front end as VB or any language then for better compatibility we will go for an interface. of which COM will be one among those interfaces. Create object creates handle to the instance of the specified object so that we program can use the methods on the specified object. It is used for implementing Automation(as defined by Microsoft).

Question 7 : Explain in brief about the QTP Automation Object Model.

Answer 7 : Essentially all configuration and run functionality provided via the Quick Test interface is in some way represented in the Quick Test automation object model via objects, methods, and properties. Although a one-on-one comparison cannot always be made, most dialog boxes in Quick Test have a corresponding automation object, most options in dialog boxes can be set and/or retrieved using the corresponding object property, and most menu commands and other operations have corresponding automation methods. You can use the objects, methods, and properties exposed by the Quick Test automation object model, along with standard programming elements such as loops and conditional statements to design your program.

Question 8 : What is the Diff between Image check-point and Bit map Check point?

Answer 8 : 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.

Question 9 : Explain the QTP Tool interface.

Answer 9 : It contains the following key elements: Title bar, displaying the name of the currently open test, Menu bar, displaying menus of Quick Test commands, File toolbar, containing buttons to assist you in managing tests, Test toolbar, containing buttons used while creating and maintaining tests, Debug toolbar, containing buttons used while debugging tests. Note: The Debug toolbar is not displayed when you open Quick Test for the first time. You can display the Debug toolbar by choosing View — Toolbars — Debug. Action toolbar, containing buttons and a list of actions, enabling you to view the details of an individual action or the entire test flow. Note: The Action toolbar is not displayed when you open Quick Test for the first time. You can display the Action toolbar by choosing View — Toolbars — Action. If you insert a reusable or external action in a test, the Action toolbar is displayed automatically. Test pane, containing two tabs to view your test-the Tree View and the Expert View ,Test Details pane, containing the Active Screen. Data Table, containing two tabs, Global and Action, to assist you in parameterizing your test. Debug Viewer pane, containing three tabs to assist you in debugging your test-Watch Expressions, Variables, and Command. (The Debug Viewer pane can be opened only when a test run pauses at a breakpoint.) Status bar, displaying the status of the test

Question 10 : What are the properties you would use for identifying a browser & page when using descriptive programming?

Answer 10 : Name would be another property apart from title that we can use.
