Interview Questions Part 8

How to make arguments optional in a function?
This is not possible as default VBS doesn't support this. Instead you can pass a blank scring and have a default value if arguments r not required.
How to add a text checkpoint to your test to check whether 'welcome' is displayed in your welcome page.
1 Locate the page where you want to add a text checkpoint.

2 Create a text checkpoint.

In the Active Screen, under your page highlight the text welcome. Right-click the highlighted text and choose Insert Text Checkpoint. The Text Checkpoint Properties dialog box opens.When Checked Text appears in the list box, the Constant field displays the text string you highlighted. This is the text QuickTest looks for when running the test.Click OK to accept the default settings in this dialog box.QuickTest adds the text checkpoint to your test. It is displayed in the Keyword View as a checkpoint operation on your welcome page3 Save the test.

How to Running and Analyzing a Test with Checkpoints?
1 Expand the test and review your test.Choose View > Expand All or use the * shortcut key on your number keypad. 

2 Start running your test.Click Run or choose Test > Run. The Run dialog box opens. Ensure that New run results folder is selected. Accept the default results folder name. Click OK. When the test run is completed, the Test Results window opens. 

3 View the test results.When QuickTest finishes running the test, the Test Results window opens. The test result should be Passed, indicating that all checkpoints passed. If one or more checkpoints had failed, the test result would be Failed. 

4 View the results of the page checkpoint.In the Details pane, you can review the details of the page checkpoint, which lists the items checked. 

5 View the results of the table checkpoint.In the Details pane, you can review the details of the table checkpoint. You can also review the values of the table cells (cell values that were checked are displayed in black; cell values that were not checked are displayed in gray). 

6 View the results of the standard checkpoint.In the Details pane, you can review the details of the standard checkpoint, which lists the properties that were checked and their values. The checkpoint passed because the actual values of the checked properties match the expected values. 

7 View the results of the text checkpoint.In the Details pane, you can review the details of the text checkpoint. The checkpoint passed because the actual text matches the expected text. 

8 Close the Test Results window. Choose File > Exit.

How to Defining a Data Table Parameter for QTP?
1 Start QuickTest and open the Checkpoint test.

2 Save the test as Parameter.

 3 Confirm that the Active Screen option is enabled.

4 Confirm that the Data Table option is enabled.

5 Select the text to parameterize.6 Set the parameterization properties.

How to add a runtime parameter to a datasheet?
DataTable.LocalSheetThe following example uses the LocalSheet property to return the local sheet of the run-time Data Table in order to add a parameter (column) to it.MyParam=DataTable.LocalSheet.AddParameter("Time", "5:45")
How to change the run-time value of a property for an object?
SetTOProperty changes the property values used to identify an object during the test run. Only properties that are included in the test object description can be set

How to retrieve the property of an object?
using "GetRoProperty".

How to open any application during Scripting?
SystemUtil , object used to open and close applications and processes during a run session.(a) A SystemUtil.Run statement is automatically added to your test when you run an application from the Start menu or the Run dialog box while recording a testE.g : SystemUtil.Run "Notepad.exe" SystemUtil.CloseDescendentProcesses ( Closes all the processes opened by QTP )

How to convert a String to an integer?
CInt()---> a conversion function available.

Inserting a Call to Action is not Importing all columns in Datatable of globalsheet. Why?
Inserting a call to action will only Import the columns of the Action called

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 oject repositoy per action and shared. In shared repository only one centralised repository for all the tests. where as in per action.for each test a separate per action repostory is created.

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

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

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.

Interview Questions Part 5

Q. What are test objects?
Test objects are objects created and maintained by QTP in its object repository. Each test objecthas a name and a set of properties to uniquely identify the actual object in the application.
 

Q. how does QTP identifies the objects during the script run?
During script run QuickTest searches for a run-time object that has the similar description of thetest object in the object repository.
 

Q. How can i check the properties of an object in an application without using checkpoints? For Example how will you check whether a button is enabled?
Answer: GetROProperty method is used to retrieve the properties of the object in an application.It is very useful method and can be used to retrieve almost any of the property that can be seenwhile spying the object with object spy. For Example‘To get whether button is enabled or not.

Val = Browser("QA Friends").Page("QA Friends"). WebButton("Login"). GetROProperty("disabled")

‘To get whether a checkbox is on or off.

Val =Browser("QA Friends").Page("QA Friends").WebCheckBox("Test").GetROProperty("Value")
 

Q. How can I modify the properties values of test objects in Object Repository during runtime?
A. You can use SetTOProperty method of test object.Object(description).SetTOProperty Property, ValueThe values of test object properties are used to identify the objects. Sometimes the properties ofthe object in the application change dynamically. For example text of a link in a webpage is theusername used to login to that page.Text property is used by test object to identify the link. So in order to identify the actual object wecan manipulate the value of “text” property of link using SetTOProperty.
 

Q. How do you synchronize your scripts in QTP?
A. For waiting until navigation of web page completes we can use Sync method. For waiting until an object appears we can use Exist method. For waiting until a property of object changes we can use WaitProperty method. You can set browser navigation timeout in: Click Test > Settings menuSelect web tab in Test Settings window. Enter the timeout in Browser Navigation Timeout text box. You can set global object sychrozization timeout in: Click Test > Settings menu Select Run tab in Test Settings window. Enter the timeout in Object Synchronization Timeout text box.
 

Q Where can you write user defined functions that are accessible by all scripts?
A. We can write user defined function in .vbs file. This file can be loaded by adding the file asfollows: Click Test > Settings menuSelect Resources tab in Test Settings window and add the file. Alternatively you can also load the file through script usingExecuteFile “absolute or relative path of file” For Example: ExecuteFile “C:\Test.vbs”

Q What are regular expressions?
A. Regular expressions used for identifying objects and text strings with varying values. You can use regular expressions for defining the property values of an object, creating checkpoints with varying values etc. Example: For example if the caption on the button in an application changes dynamically and can be anything which starts with “Hello” (It can be Hello XYZ, Hello AB13 and so on) You can go object repository and change the value of name property of the button object to” Hello.*”Here “.” means any single character and “*” means 0 or more occurrences of preceding character. So.* means 0 or more occurrences of any character. There are many other regular expression characters: For Example: Regular expression test[0-9] matches test0, test1, test2…… to test9.Regular expression abc[789] matches abc7, abc8, abc9Q. Different ways to parameterize tests? A. Test, action or component parameters – for using values from other action in your test. Data Table parameters – for creating data driven test based on values in data table. Environment variable parameters – For using values of environment variable. Random number parameters – For using random numbers as values in our test or component.
Q. What can you do if values of object properties in an application are changing constantly?
A. We can try using alternatives like regular expressions, Changing description of test objects in object repository during run time, using descriptive programming and so on.
Q. What can you do if objects are not identified by QTP?
A. 1) For standard windows environment you can try object mapping user defined classes to standard classes.2)You can find whether any addins are available for given environment.3) check if any other reliable alternatives are available like using keyboard shortcuts, using automation object model of application if available and so on.
Q. What is descriptive programming?
A. Descriptive programming allows you to work with objects that are not stored in objectrepository. two types of programmatic descriptions.1) listing the set of properties and values that describe the object directly in a teststatement.2) Add collection of properties and values to a Description object, and then enter the Description object name in the statement.
 

Q. How will you access database from QTP?
A. You can use ActiveX Data Object for accessing the content of database. You cancreate connection object, recordset object and then execute query. And access the valuesof query in recordset.

Example Set objConn= CreateObject("ADODB.connection")

   Set objRecSet = CreateObject("ADODB.recordset")objConn.open strConString

'strConString is database connection string.objRecSet.open strQuery,objConn 'strQuery is SQL query to execute.
