- What is think time? How do you change the threshold? – Think time is the time that a real user waits between actions. Example: When a user receives data from a server, the user may wait several seconds to review the data before responding. This delay is known as the think time. Changing the Threshold: Threshold level is the level below which the recorded think time will be ignored. The default value is five (5) seconds. We can change the think time threshold in the Recording options of the Vugen.
- What is the difference between standard log and extended log? – The standard log sends a subset of functions and messages sent during script execution to a log. The subset depends on the Vuser type Extended log sends a detailed script execution messages to the output log. This is mainly used during debugging when we want information about: Parameter substitution. Data returned by the server. Advanced trace.
- Explain the following functions: – lr_debug_message – The lr_debug_message function sends a debug message to the output log when the specified message class is set. lr_output_message – The lr_output_message function sends notifications to the Controller Output window and the Vuser log file. lr_error_message – The lr_error_message function sends an error message to the LoadRunner Output window. lrd_stmt – The lrd_stmt function associates a character string (usually a SQL statement) with a cursor. This function sets a SQL statement to be processed. lrd_fetch – The lrd_fetch function fetches the next row from the result set.
- Throughput – If the throughput scales upward as time progresses and the number of Vusers increase, this indicates that the bandwidth is sufficient. If the graph were to remain relatively flat as the number of Vusers increased, it would
be reasonable to conclude that the bandwidth is constraining the volume of
- Types of Goals in Goal-Oriented Scenario – Load Runner provides you with five different types of goals in a goal oriented scenario:
- The number of concurrent Vusers
- The number of hits per second
- The number of transactions per second
- The number of pages per minute
- The transaction response time that you want your scenario
- Analysis Scenario (Bottlenecks): In Running Vuser graph correlated with the response time graph you can see that as the number of Vusers increases, the average response time of the check itinerary transaction very gradually increases. In other words, the average response time steadily increases as the load
increases. At 56 Vusers, there is a sudden, sharp increase in the average response
time. We say that the test broke the server. That is the mean time before failure (MTBF). The response time clearly began to degrade when there were more than 56 Vusers running simultaneously.
- What is correlation? Explain the difference between automatic correlation and manual correlation? – Correlation is used to obtain data which are unique for each run of the script and which are generated by nested queries. Correlation provides the value to avoid errors arising out of duplicate values and also optimizing the code (to avoid nested queries). Automatic correlation is where we set some rules for correlation. It can be application server specific. Here values are replaced by data which are created by these rules. In manual correlation, the value we want to correlate is scanned and create correlation is used to correlate.
- Where do you set automatic correlation options? – Automatic correlation from web point of view, can be set in recording options and correlation tab. Here we can enable correlation for the entire script and choose either issue online messages or offline actions, where we can define rules for that correlation. Automatic correlation for database, can be done using show output window and scan for correlation and picking the correlate query tab and choose which query value we want to correlate. If we know the specific value to be correlated, we just do create correlation for the value and specify how the value to be created.
- What is a function to capture dynamic values in the web vuser script? – Web_reg_save_param function saves dynamic data information to a parameter.

- Black box testing
- not based on any knowledge of internal design or code. Tests are based on requirements and functionality.
- White box testing
- based on knowledge of the internal logic of an application’s code. Tests are based on coverage of code statements, branches, paths, conditions.
- Unit testing
- the most ‘micro’ scale of testing; to test particular functions or code modules. Typically done by the programmer and not by testers, as it requires detailed knowledge of the internal program design and code. Not always easily done unless the application has a well-designed architecture with tight code; may require developing test driver modules or test harnesses.
- Incremental integration testing
- continuous testing of an application as new functionality is added; requires that various aspects of an application’s functionality be independent enough to work separately before all parts of the program are completed, or that test drivers be developed as needed; done by programmers or by testers.
- Integration testing
- testing of combined parts of an application to determine if they function together correctly. The ‘parts’ can be code modules, individual applications, client and server applications on a network, etc. This type of testing is especially relevant to client/server and distributed systems.
- Functional testing
- black-box type testing geared to functional requirements of an application; this type of testing should be done by testers. This doesn’t mean that the programmers shouldn’t check that their code works before releasing it (which of course applies to any stage of testing.)
- System testing
- black box type testing that is based on overall requirement specifications; covers all combined parts of a system.
- End-to-end testing
- similar to system testing; the ‘macro’ end of the test scale; involves testing of a complete application environment in a situation that mimics real-world use, such as interacting with a database, using network communications, or interacting with other hardware, applications, or systems if appropriate.
- Sanity testing
- typically an initial testing effort to determine if a new software version is performing well enough to accept it for a major testing effort. For example, if the new software is crashing systems every 5 minutes, bogging down systems to a crawl, or destroying databases, the software may not be in a ’sane’ enough condition to warrant further testing in its current state.
- Regression testing
- re-testing after fixes or modifications of the software or its environment. It can be difficult to determine how much re-testing is needed, especially near the end of the development cycle. Automated testing tools can be especially useful for this type of testing.
- Acceptance testing
- final testing based on specifications of the end-user or customer, or based on use by end-users/customers over some limited period of time.
- Load testing
- testing an application under heavy loads, such as testing of a web site under a range of loads to determine at what point the systems response time degrades or fails.
- Stress testing
- term often used interchangeably with ‘load’ and ‘performance’ testing. Also used to describe such tests as system functional testing while under unusually heavy loads, heavy repetition of certain actions or inputs, input of large numerical values, large complex queries to a database system, etc.
- Performance testing
- term often used interchangeably with ’stress’ and ‘load’ testing. Ideally ‘performance’ testing (and any other ‘type’ of testing) is defined in requirements documentation or QA or Test Plans.
- Usability testing
- testing for ‘user-friendliness’. Clearly this is subjective, and will depend on the targeted end-user or customer. User interviews, surveys, video recording of user sessions, and other techniques can be used. Programmers and testers are usually not appropriate as usability testers.
- Install/uninstall testing
- testing of full, partial, or upgrade install/uninstall processes.
- Recovery testing
- testing how well a system recovers from crashes, hardware failures, or other catastrophic problems.
- Security testing
- testing how well the system protects against unauthorized internal or external access, willful damage, etc; may require sophisticated testing techniques.
- Compatibility testing
- testing how well software performs in a particular hardware/software/operating system/network/etc. environment.
- Exploratory testing
- often taken to mean a creative, informal software test that is not based on formal test plans or test cases; testers may be learning the software as they test it.
- Ad-hoc testing
- similar to exploratory testing, but often taken to mean that the testers have significant understanding of the software before testing it.
- User acceptance testing
- determining if software is satisfactory to an end-user or customer.
- Comparison testing
- comparing software weaknesses and strengths to competing products.
- Alpha testing
- testing of an application when development is nearing completion; minor design changes may still be made as a result of such testing. Typically done by end-users or others, not by programmers or testers.
- Beta testing
- testing when development and testing are essentially completed and final bugs and problems need to be found before final release. Typically done by end-users or others, not by programmers or testers.
- Mutation testing
- a method for determining if a set of test data or test cases is useful, by deliberately introducing various code changes (’bugs’) and retesting with the original test data/cases to determine if the ‘bugs’ are detected. Proper implementation requires large computational resources.

- How to handle the exceptions using recovery scenario manager in QTP? – There are 4 trigger events during which a recovery scenario should be activated. A pop up window appears in an opened application during the test run: A property of an object changes its state or value, A step in the test does not run successfully, An open application fails during the test run, These triggers are considered as exceptions.You can instruct QTP to recover unexpected events or errors that occurred in your testing environment during test run. Recovery scenario manager provides a wizard that guides you through the defining recovery scenario. Recovery scenario has three steps: 1. Triggered Events 2. Recovery steps 3. Post Recovery Test-Run
- What is the use of Text output value in QTP? – Output values enable to view the values that the application talks during run time. When parameterized, the values change for each iteration. Thus by creating output values, we can capture the values that the application takes for each run and output them to the data table.
- How to use the Object spy in QTP 8.0 version? – There are two ways to Spy the objects in QTP: 1) Thru file toolbar, In the File Toolbar click on the last toolbar button (an icon showing a person with hat). 2) True Object repository Dialog, In Object repository dialog click on the button object spy. In the Object spy Dialog click on the button showing hand symbol. The pointer now changes in to a hand symbol and we have to point out the object to spy the state of the object if at all the object is not visible. or window is minimized then, hold the Ctrl button and activate the required window to and release the Ctrl button.
- How Does Run time data (Parameterization) is handled in QTP? – You can then enter test data into the Data Table, an integrated spreadsheet with the full functionality of Excel, to manipulate data sets and create multiple test iterations, without programming, to expand test case coverage. Data can be typed in or imported from databases, spreadsheets, or text files.
- What is keyword view and Expert view in QTP? – Quick Test’s Keyword Driven approach, test automation experts have full access to the underlying test and object properties, via an integrated scripting and debugging environment that is round-trip synchronized with the Keyword View. Advanced testers can view and edit their tests in the Expert View, which reveals the underlying industry-standard VBScript that Quick Test Professional automatically generates. Any changes made in the Expert View are automatically synchronized with the Keyword View.
- Explain about the Test Fusion Report of QTP? – Once a tester has run a test, a Test Fusion report displays all aspects of the test run: a high-level results overview, an expandable Tree View of the test specifying exactly where application failures occurred, the test data used, application screen shots for every step that highlight any discrepancies, and detailed explanations of each checkpoint pass and failure. By combining Test Fusion reports with Quick Test Professional, you can share reports across an entire QA and development team.
- Which environments does QTP support? – Quick Test Professional supports functional testing of all enterprise environments, including Windows, Web,..NET, Java/J2EE, SAP, Siebel, Oracle, PeopleSoft, Visual Basic, ActiveX, mainframe terminal emulators, and Web services.
- What is QTP? – Quick Test is a graphical interface record-playback automation tool. It is able to work with any web, java or windows client application. Quick Test enables you to test standard web objects and ActiveX controls. In addition to these environments, Quick Test Professional also enables you to test Java applets and applications and multimedia objects on Applications as well as standard Windows applications, Visual Basic 6 applications and.NET framework applications
- Explain QTP Testing process? – Quick Test testing process consists of 6 main phases:
Create your test plan – Prior to automating there should be a detailed description of the test including the exact steps to follow, data to be input, and all items to be verified by the test. The verification information should include both data validations and existence or state verifications of objects in the application.
Recording a […]
- Create your test plan – Prior to automating there should be a detailed description of the test including the exact steps to follow, data to be input, and all items to be verified by the test. The verification information should include both data validations and existence or state verifications of objects in the application.
- Recording a session on your application – As you navigate through your application, Quick Test graphically displays each step you perform in the form of a collapsible icon-based test tree. A step is any user action that causes or makes a change in your site, such as clicking a link or image, or entering data in a form.
- Enhancing your test – Inserting checkpoints into your test lets you search for a specific value of a page, object or text string, which helps you identify whether or not your application is functioning correctly. NOTE: Checkpoints can be added to a test as you record it or after the fact via the Active Screen. It is much easier and faster to add the checkpoints during the recording process. Broadening the scope of your test by replacing fixed values with parameters lets you check how your application performs the same operations with multiple sets of data. Adding logic and conditional statements to your test enables you to add sophisticated checks to your test.
- Debugging your test – If changes were made to the script, you need to debug it to check that it operates smoothly and without interruption.
- Running your test on a new version of your application – You run a test to check the behavior of your application. While running, Quick Test connects to your application and performs each step in your test.
- Analyzing the test results – You examine the test results to pinpoint defects in your application.
- Reporting defects – As you encounter failures in the application when analyzing test results, you will create defect reports in Defect Reporting Tool.
- Explain the QTP Tool interface. – 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
- How does QTP recognize Objects in AUT? – Quick Test stores the definitions for application objects in a file called the Object Repository. As you record your test, Quick Test will add an entry for each item you interact with. Each Object Repository entry will be identified by a logical name (determined automatically by Quick Test), and will contain a set of properties (type, name, etc) that uniquely identify each object. Each line in the Quick Test script will contain a reference to the object that you interacted with, a call to the appropriate method (set, click, check) and any parameters for that method (such as the value for a call to the set method). The references to objects in the script will all be identified by the logical name, rather than any physical, descriptive properties.
- What are the types of Object Repositories in QTP? – Quick Test has two types of object repositories for storing object information: shared object repositories and action object repositories. You can choose which type of object repository you want to use as the default type for new tests, and you can change the default as necessary for each new test. The object repository per-action mode is the default setting. In this mode, Quick Test automatically creates an object repository file for each action in your test so that you can create and run tests without creating, choosing, or modifying object repository files. However, if you do modify values in an action object repository, your changes do not have any effect on other actions. Therefore, if the same test object exists in more than one action and you modify an object’s property values in one action, you may need to make the same change in every action (and any test) containing the object.
