What do you verify with the database checkpoint default and what command it generates, explain syntax? ( WinRunner Question )

What do you verify with the database checkpoint default and what command it generates, explain syntax? ( WinRunner Question )


What do you verify with the database checkpoint default and what command it generates, explain syntax?

• By adding runtime database record checkpoints you can compare the information in your application during a test run with the corresponding record in your database. By adding standard database checkpoints to your test scripts, you can check the contents of databases in different versions of your application.


• When you create database checkpoints, you define a query on your database, and your database checkpoint checks the values contained in the result set. The result set is set of values retrieved from the results of the query.


• You can create runtime database record checkpoints in order to compare the values displayed in your application during the test run with the corresponding values in the database. If the comparison does not meet the success criteria you


• Specify for the checkpoint, the checkpoint fails. You can define a successful runtime database record checkpoint as one where one or more matching records were found, exactly one matching record was found, or where no matching records are found.


• You can create standard database checkpoints to compare the current values of the properties of the result set during the test run to the expected values captured during recording or otherwise set before the test run. If the expected results and the current results do not match, the database checkpoint fails. Standard database checkpoints are useful when the expected results can be established before the test run.

Syntax: db_check(, );

• You can add a runtime database record checkpoint to your test in order to compare information that appears in your application during a test run with the current value(s) in the corresponding record(s) in your database. You add runtime database record checkpoints by running the Runtime Record Checkpoint wizard. When you are finished, the wizard inserts the appropriate db_record_check statement into your script.

Syntax:
db_record_check(ChecklistFileName,SuccessConditions,RecordNumber );

ChecklistFileName A file created by WinRunner and saved in the test's checklist folder. The file contains information about the data to be captured during the test run and its corresponding field in the database. The file is created based on the information entered in the Runtime Record Verification wizard.
SuccessConditions Contains one of the following values:

1. DVR_ONE_OR_MORE_MATCH - The checkpoint passes if one or more matching database records are found.


2. DVR_ONE_MATCH - The checkpoint passes if exactly one matching database record is found.


3. DVR_NO_MATCH - The checkpoint passes if no matching database records are found.

RecordNumber An out parameter returning the number of records in the database.

What do you verify with the bitmap checkpoint for screen area and what command it generates, explain syntax? ( WinRunner Question )

What do you verify with the bitmap checkpoint for screen area and what command it generates, explain syntax? ( WinRunner Question )


What do you verify with the bitmap checkpoint for screen area and what command it generates, explain syntax?

• You can define any rectangular area of the screen and capture it as a bitmap for comparison. The area can be any size: it can be part of a single window, or it can intersect several windows. The rectangle is identified by the coordinates of its upper left and lower right corners, relative to the upper left corner of the window in which the area is located. If the area intersects several windows or is part of a window with no title (for example, a popup window), its coordinates are relative to the entire screen (the root window).

• To capture an area of the screen as a bitmap:

• Choose Create > Bitmap Checkpoint > For Screen Area or click the Bitmap Checkpoint for Screen Area button. Alternatively, if you are recording in Analog mode, press the CHECK BITMAP OF SCREEN AREA softkey. The WinRunner window is minimized, the mouse pointer becomes a crosshairs pointer, and a help window opens.


• Mark the area to be captured: press the left mouse button and drag the mouse pointer until a rectangle encloses the area; then release the mouse button.


• Press the right mouse button to complete the operation. WinRunner captures the area and generates a win_check_bitmap statement in your script.


• The win_check_bitmap statement for an area of the screen has the following syntax:

win_check_bitmap ( window, bitmap, time, x, y, width, height );

What do you verify with the bitmap check point for object/window and what command it generates, explain syntax? ( WinRunner Question )

What do you verify with the bitmap check point for object/window and what command it generates, explain syntax? ( WinRunner Question )


What do you verify with the bitmap check point for object/window and what command it generates, explain syntax?

• You can check an object, a window, or an area of a screen in your application as a bitmap. While creating a test, you indicate what you want to check. WinRunner captures the specified bitmap, stores it in the expected results folder (exp) of the test, and inserts a checkpoint in the test script. When you run the test, WinRunner compares the bitmap currently displayed in the application being tested with the expected bitmap stored earlier. In the event of a mismatch, WinRunner captures the current actual bitmap and generates a difference bitmap. By comparing the three bitmaps (expected, actual, and difference), you can identify the nature of the discrepancy.


• When working in Context Sensitive mode, you can capture a bitmap of a window, object, or of a specified area of a screen. WinRunner inserts a checkpoint in the test script in the form of either a win_check_bitmap or obj_check_bitmap statement.


• Note that when you record a test in Analog mode, you should press the CHECK BITMAP OF WINDOW softkey or the CHECK BITMAP OF SCREEN AREA softkey to create a bitmap checkpoint. This prevents WinRunner from recording extraneous mouse movements. If you are programming a test, you can also use the Analog function check_window to check a bitmap.

• To capture a window or object as a bitmap:

• Choose Create > Bitmap Checkpoint > For Object/Window or click the Bitmap Checkpoint for Object/Window button on the User toolbar. Alternatively, if you are recording in Analog mode, press the CHECK BITMAP OF OBJECT/WINDOW softkey. The WinRunner window is minimized, the mouse pointer becomes a pointing hand, and a help window opens.


• Point to the object or window and click it. WinRunner captures the bitmap and generates a win_check_bitmap or obj_check_bitmap statement in the script. The TSL statement generated for a window bitmap has the following syntax:

win_check_bitmap ( object, bitmap, time );

• For an object bitmap, the syntax is:

obj_check_bitmap ( object, bitmap, time );

• For example, when you click the title bar of the main window of the Flight Reservation application, the resulting statement might be:

win_check_bitmap ("Flight Reservation", "Img2", 1);

• However, if you click the Date of Flight box in the same window, the statement might be:

obj_check_bitmap ("Date of Flight:", "Img1", 1);

Syntax: obj_check_bitmap ( object, bitmap, time [, x, y, width, height] );

What do you verify with the GUI checkpoint for multiple objects and what command it generates, explain syntax? ( WinRunner Question )

What do you verify with the GUI checkpoint for multiple objects and what command it generates, explain syntax? ( WinRunner Question )


To create a GUI checkpoint for two or more objects:

• Choose Create > GUI Checkpoint > For Multiple Objects or click the GUI Checkpoint for Multiple Objects button on the User toolbar. If you are recording in Analog mode, press the CHECK GUI FOR MULTIPLE OBJECTS softkey in order to avoid extraneous mouse movements. The Create GUI Checkpoint dialog box opens.


• Click the Add button. The mouse pointer becomes a pointing hand and a help window opens.


• To add an object, click it once. If you click a window title bar or menu bar, a help window prompts you to check all the objects in the window.


• The pointing hand remains active. You can continue to choose objects by repeating step 3 above for each object you want to check.


• Click the right mouse button to stop the selection process and to restore the mouse pointer to its original shape. The Create GUI Checkpoint dialog box reopens.

• To edit the expected value of a property, first select it. Next, either click the Edit Expected Value button, or double-click the value in the Expected Value column to edit it.


• To add a check in which you specify arguments, first select the property for which you want to specify arguments. Next, either click the Specify Arguments button, or double-click in the Arguments column. Note that if an ellipsis appears in the Arguments column, then you must specify arguments for a check on this property. (You do not need to specify arguments if a default argument is specified.) When checking standard objects, you only specify arguments for certain properties of edit and static text objects. You also specify arguments for checks on certain properties of nonstandard objects.


• To change the viewing options for the properties of an object, use the Show Properties buttons.


• To save the checklist and close the Create GUI Checkpoint dialog box, click OK. WinRunner captures the current property values of the selected GUI objects and stores it in the expected results folder. A win_check_gui statement is inserted in the test script.

Syntax: win_check_gui ( window, checklist, expected_results_file, time );
obj_check_gui ( object, checklist, expected results file, time );

What information is contained in the checklist file and in which file expected results are stored? ( WinRunner Question )

What information is contained in the checklist file and in which file expected results are stored? ( WinRunner Question )


Winrunner Question 55: What information is contained in the checklist file and in which file expected results are stored?

• The checklist file contains information about the objects and the properties of the object we are verifying.


• The gui*.chk file contains the expected results which is stored in the exp folder

What do you verify with the GUI checkpoint for object/window and what command it generates, explain syntax? ( WinRunner question )

What do you verify with the GUI checkpoint for object/window and what command it generates, explain syntax? ( WinRunner question )

• You can create a GUI checkpoint to check a single object in the application being tested. You can either check the object with its default properties or you can specify which properties to check.


• Creating a GUI Checkpoint using the Default Checks


• You can create a GUI checkpoint that performs a default check on the property recommended by WinRunner. For example, if you create a GUI checkpoint that checks a push button, the default check verifies that the push button is enabled.


• To create a GUI checkpoint using default checks:


• Choose Create > GUI Checkpoint > For Object/Window, or click the GUI Checkpoint for Object/Window button on the User toolbar. If you are recording in Analog mode, press the CHECK GUI FOR OBJECT/WINDOW softkey in order to avoid extraneous mouse movements.

What do you verify with the GUI checkpoint for single property and what command it generates, explain syntax? ( WinRunner Question )

What do you verify with the GUI checkpoint for single property and what command it generates, explain syntax? ( WinRunner Question )


You can check a single property of a GUI object. For example, you can check whether a button is enabled or disabled or whether an item in a list is selected. To create a GUI checkpoint for a property value, use the Check Property dialog box to add one of the following functions to the test script:

• button_check_info


• scroll_check_info


• edit_check_info


• static_check_info


• list_check_info


• win_check_info


• obj_check_info

Syntax:
button_check_info (button, property, property_value );
edit_check_info ( edit, property, property_value );

How do you maintain the document information of the test scripts? ( WinRunner Question )

How do you maintain the document information of the test scripts? ( WinRunner Question )

Before creating a test, you can document information about the test in the General and Description tabs of the Test Properties dialog box. You can enter the name of the test author, the type of functionality tested, a detailed description of the test, and a reference to the relevant functional specifications document.

What is parameterizing? (WinRunner Question )

What is parameterizing? (WinRunner Question )

In order for WinRunner to use data to drive the test, you must link the data to the test script which it drives. This is called parameterizing your test. The data is stored in a data table.

What are the synchronization points?( WinRunner Question )

What are the synchronization points?( WinRunner Question )

• Synchronization points enable you to solve anticipated timing problems between the test and your application. For example, if you create a test that opens a database application, you can add a synchronization point that causes the test to wait until the database records are loaded on the screen.


• For Analog testing, you can also use a synchronization point to ensure that WinRunner repositions a window at a specific location. When you run a test, the mouse cursor travels along exact coordinates. Repositioning the window enables the mouse pointer to make contact with the correct elements in the window.

What are data driven tests? ( WinRunner Question )

What are data driven tests? ( WinRunner Question )


When you test your application, you may want to check how it performs the same operations with multiple sets of data. You can create a data-driven test with a loop that runs ten times: each time the loop runs, it is driven by a different set of data. In order for WinRunner to use data to drive the test, you must link the data to the test script which it drives. This is called parameterizing your test. The data is stored in a data table. You can perform these operations manually, or you can use the DataDriver Wizard to parameterize your test and store the data in a data table.

What is a checkpoint and what are different types of checkpoints? ( WinRunner Question )

What is a checkpoint and what are different types of checkpoints? ( WinRunner Question )

Checkpoints allow you to compare the current behavior of the application being tested to its behavior in an earlier version.

You can add four types of checkpoints to your test scripts:

• GUI checkpoints verify information about GUI objects. For example, you can check that a button is enabled or see which item is selected in a list.


• Bitmap checkpoints take a “snapshot” of a window or area of your application and compare this to an image captured in an earlier version.


• Text checkpoints read text in GUI objects and in bitmaps and enable you to verify their contents.


• Database checkpoints check the contents and the number of rows and columns of a result set, which is based on a query you create on your database.

What are the two modes of recording? ( WinRunner Question )

What are the two modes of recording? ( WinRunner Question )

There are 2 modes of recording in WinRunner

• Context Sensitive recording records the operations you perform on your application by identifying Graphical User Interface (GUI) objects.


• Analog recording records keyboard input, mouse clicks, and the precise x- and y-coordinates traveled by the mouse pointer across the screen

What are the virtual objects and how do you learn them? ( WinRunner Question )

What are the virtual objects and how do you learn them? ( WinRunner Question )


What are the virtual objects and how do you learn them?

• Applications may contain bitmaps that look and behave like GUI objects. WinRunner records operations on these bitmaps using win_mouse_click statements. By defining a bitmap as a virtual object, you can instruct WinRunner to treat it like a GUI object such as a push button, when you record and run tests.


• Using the Virtual Object wizard, you can assign a bitmap to a standard object class, define the coordinates of that object, and assign it a logical name.

To define a virtual object using the Virtual Object wizard:

• Choose Tools > Virtual Object Wizard. The Virtual Object wizard opens. Click Next.


• In the Class list, select a class for the new virtual object. If rows that are displayed in the window. For a table class, select the number of visible rows and columns. Click Next.


• Click Mark Object. Use the crosshairs pointer to select the area of the virtual object. You can use the arrow keys to make precise adjustments to the area you define with the crosshairs. Press Enter or click the right mouse button to display the virtual object’s coordinates in the wizard. If the object marked is visible on the screen, you can click the Highlight button to view it. Click Next.


• Assign a logical name to the virtual object. This is the name that appears in the test script when you record on the virtual object. If the object contains text that WinRunner can read, the wizard suggests using this text for the logical name. Otherwise, WinRunner suggests virtual_object, virtual_push_button, virtual_list, etc.

How do you find out which is the start up file in WinRunner? ( WinRunner Question )

How do you find out which is the start up file in WinRunner? ( WinRunner Question )


The test script name in the Startup Test box in the Environment tab in the General Options dialog box is the start up file in WinRunner.

What is the purpose of different record methods 1) Record 2) Pass up 3) As Object 4) Ignore.

What is the purpose of different record methods 1) Record 2) Pass up 3) As Object 4) Ignore. ( winRunner Question )

• Record instructs WinRunner to record all operations performed on a GUI object. This is the default record method for all classes. (The only exception is the static class (static text), for which the default is Pass Up.)


• Pass Up instructs WinRunner to record an operation performed on this class as an operation performed on the element containing the object. Usually this element is a window, and the operation is recorded as win_mouse_click.


• As Object instructs WinRunner to record all operations performed on a GUI object as though its class were “object” class.


• Ignore instructs WinRunner to disregard all operations performed on the class.

In a situation when obligatory and optional both the properties cannot uniquely identify an object what method WinRunner applies? WinRunner Question

In a situation when obligatory and optional both the properties cannot uniquely identify an object what method WinRunner applies? WinRunner Question


In a situation when obligatory and optional both the properties cannot uniquely identify an object what method WinRunner applies?
In cases where the obligatory and optional properties do not uniquely identify an object, WinRunner uses a selector to differentiate between them. Two types of selectors are available:

* A location selector uses the spatial position of objects.

* An index selector uses a unique number to identify the object in a window.

What is the name of custom class in WinRunner and what methods it applies on the custom objects? ( WinRunner Question )

What is the name of custom class in WinRunner and what methods it applies on the custom objects? ( WinRunner Question )


WinRunner learns custom class objects under the generic “object” class. WinRunner records operations on custom objects using obj_ statements.

How do you handle custom objects? ( WinRunner Question )

How do you handle custom objects? ( WinRunner Question )

A custom object is any GUI object not belonging to one of the standard classes used by WinRunner. WinRunner learns such objects under the generic “object” class. WinRunner records operations on custom objects using obj_mouse_ statements.
If a custom object is similar to a standard object, you can map it to one of the standard classes. You can also configure the properties WinRunner uses to identify a custom object during Context Sensitive testing.

What is the purpose of location indicator and index indicator in GUI map configuration? ( WinRunner Question )

What is the purpose of location indicator and index indicator in GUI map configuration? ( WinRunner Question )

In cases where the obligatory and optional properties do not uniquely identify an object, WinRunner uses a selector to differentiate between them. Two types of selectors are available:

• A location selector uses the spatial position of objects.

The location selector uses the spatial order of objects within the window, from the top left to the bottom right corners, to differentiate among objects with the same description.

• An index selector uses a unique number to identify the object in a window.

The index selector uses numbers assigned at the time of creation of objects to identify the object in a window. Use this selector if the location of objects with the same description may change within a window.

When the optional properties are learned? ( WinRunner Question )

When the optional properties are learned? ( WinRunner Question )

When the optional properties are learned?
An optional property is used only if the obligatory properties do not provide unique identification of an object.

What is the purpose of obligatory and optional properties of the objects? ( WinRunner Questions )

What is the purpose of obligatory and optional properties of the objects? ( WinRunner Questions )

For each class, WinRunner learns a set of default properties. Each default property is classified “obligatory” or “optional”.

• An obligatory property is always learned (if it exists).


• An optional property is used only if the obligatory properties do not provide unique identification of an object. These optional properties are stored in a list. WinRunner selects the minimum number of properties from this list that are necessary to identify the object. It begins with the first property in the list, and continues, if necessary, to add properties to the description until it obtains unique identification for the object.

What is the purpose of GUI spy? ( WinRunner Question)

What is the purpose of GUI spy? ( WinRunner Question)

Using the GUI Spy, you can view the properties of any GUI object on your desktop. You use the Spy pointer to point to an object, and the GUI Spy displays the properties and their values in the GUI Spy dialog box. You can choose to view all the properties of an object, or only the selected set of properties that WinRunner learns.

What is the purpose of GUI map configuration? How do you make the configuration and mappings permanent? ( WinRunner Question )

What is the purpose of GUI map configuration? How do you make the configuration and mappings permanent? ( WinRunner Question )

What is the purpose of GUI map configuration?
GUI Map configuration is used to map a custom object to a standard object.

How do you make the configuration and mappings permanent?
The mapping and the configuration you set are valid only for the current WinRunner session. To make the mapping and the configuration permanent, you must add configuration statements to your startup test script
