QTP 8.2 Tips & Tricks

Well this post is about tips on various topics. I will try to cover as many as i have in mind and would try to

summarize the tips that people have given on the forum

Data Table

Two Types of data tables

Global data sheet: Accessible to all the actionsLocal data sheet: Accessible to the associated action only

Usage:

DataTable("Column Name",dtGlobalSheet) for Global data sheet

DataTable("Column Name",dtLocalSheet) for Local data sheet

If we change any thing in the Data Table at Run-Time the data is changed only in the run-time data table.

The run-time data table is accessible only through then test result. The run-time data table can also be

exported using DataTable.Export or DataTable.ExportSheet

How can I save the changes to my DataTable in the test itself?Well QTP does not allow anything for saving the run time changes to the actual data sheet. The only work

around is to share the spreadsheet and then access it using the Excel COM Api's.

How can I check if a parameter exists in DataTable or not?

The best way would be to use the below code:code:

on error resume next

val=DataTable("ParamName",dtGlobalSheet)if err.number 0 then

'Parameter does not exist

else'Parameter existsend if

How can I make some rows colored in the data table?

Well you can't do it normally but you can use Excel COM API's do the same. Below code will explain

some expects of Excel COM APIs

code:

Set xlApp=Createobject("Excel.Application")set xlWorkBook=xlApp.workbooks.add

set xlWorkSheet=xlWorkbook.worksheet.addxlWorkSheet.Range("A1:B10").interior.colorindex = 34 'Change the color of the cells

xlWorkSheet.Range("A1:A10").value="text" 'Will set values of all 10 rows to "text"

xlWorkSheet.Cells(1,1).value="Text" 'Will set the value of first row and first col

rowsCount=xlWorkSheet.Evaluate("COUNTA(A:A)") 'Will count the # of rows which have non blank

value in the column A

colsCount=xlWorkSheet.Evaluate("COUNTA(1:1)") 'Will count the # of non blank columns in 1st row

to next step etc....

When to use a Recovery Scenario and when to us on error resume next?

Recovery scenarios are used when you cannot predict at what step the error can occur or when you knowthat error won't occur in your

QTP script but could occur in the world outside QTP, again the example would be "out of paper", as this

error is caused by printer device driver. "On

error resume next" should be used when you know if an error is expected and dont want to raise it, you

may want to have different actions

depending upon the error that occurred. Use err.number & err.description to get more details about the

error.

Library Files or VBScript Files

How do we associate a library file with a test ?

Library files are files containing normal VBScript code. The file can contain function, sub procedure,classes etc.... You can also use executefile

function to include a file at run-time also. To associate a library file with your script go to Test->Settings...

and add your library file to resources

tab.

When to associate a library file with a test and when to use execute file?

When we associate a library file with the test, then all the functions within that library are available to all

the actions present in the test. But

when we use Executefile function to load a library file, then the function are available in the action thatcalled executefile. By associated a library to

a test we share variables across action (global variables basically), using association also makes it possibleto execute code as soon as the script

runs because while loading the script on startup QTP executes all the code on the global scope. We can useexecutefile in a library file associated

with the test to load dynamic files and they will be available to all the actions in the test.

Add-ins

Test and Run-time Object

What is the difference between Test Objects and Run Time Objects ?

Test objects are basic and generic objects that QTP recognize. Run time object means the actual object to

which a test object maps.

Can i change properties of a test object

Yes. You can use SetTOProperty to change the test object properties. It is recommended that you switch


4/5

off the Smart Identification for the

object on which you use SetTOProperty function.

Can i change properties of a run time object?

No (but Yes also). You can use GetROProperty("outerText") to get the outerText of a object but there is nofunction like SetROProperty to

change this property. But you can use WebElement().object.outerText="Something" to change the

property.

Action & Functions

What is the difference between an Action and a function?

Action is a thing specific to QTP while functions are a generic thing which is a feature of VB Scripting.

Action can have a object repository

associated with it while a function can't. A function is just lines of code with some/none parameters and a

single return value while an action can

have more than one output parameters.

Where to use function or action?

Well answer depends on the scenario. If you want to use the OR feature then you have to go for Actiononly. If the functionality is not about any

automation script i.e. a function like getting a string between to specific characters, now this is somethingnot specific to QTP and can be done on

pure VB Script, so this should be done in a function and not an action. Code specific to QTP can also beput into an function using DP. Decision of

using function/action depends on what any one would be comfortable using in a given situation.

Checkpoint & Output value

What is checkpoint?

Checkpoint is basically a point in the test which validates for truthfulness of a specific things in the AUT.

There are different types of

checkpoints depending on the type of data that needs to be tested in the AUT. It can be text, image/bitmap,

attributes, XML etc....

What's the difference between a checkpoint and output value?

Checkpoint only checks for the specific attribute of an object in AUT while Output value can output thoseattributes value to a column in data

table.

How can i check if a checkpoint passes or not?

code:

chk_PassFail = Browser(...).Page(...).WebEdit(...).Check (Checkpoint("Check1"))if chk_PassFail then

MsgBox "Check Point passed"

elseMsgBox "Check Point failed"


5/5

end if

My test fails due to checkpoint failing, Can i validate a checkpoint without my test failing due to

checpoint failure?

code:Reporter.Filter = rfDisableAll 'Disables all the reporting stuff

chk_PassFail = Browser(...).Page(...).WebEdit(...).Check (Checkpoint("Check1"))

Reporter.Filter = rfEnableAll 'Enable all the reporting stuff

if chk_PassFail thenMsgBox "Check Point passed"

else

MsgBox "Check Point failed"end if

Environment

How can i import environment from a file on disk

Environment.LoadFromFile "C:\Env.xml"

How can i check if a environment variable exist or not?

When we use Environment("Param1").value then QTP expects the environment variable to be already

defined. But when we use

Environment.value("Param1") then QTP will create a new internal environment variable if it does notexists already. So to be sure that variable exist

in the environment try using Environment("Param1").value.

How to connect to a database?

code:

Const adOpenStatic = 3

Const adLockOptimistic = 3Const adUseClient = 3Set objConnection = CreateObject("ADODB.Connection")

Set objRecordset = CreateObject("ADODB.Recordset")

objConnection.Open "DRIVER={Microsoft ODBC for Oracle};UID=;PWD="

objRecordset.CursorLocation = adUseClient

objRecordset.CursorType = adopenstaticobjRecordset.LockType = adlockoptimistic

ObjRecordset.Source="select field1,field2 from testTable"

ObjRecordset.ActiveConnection=ObjConnection

ObjRecordset.Open 'This will execute your QueryIf ObjRecordset.recordcount>0 then

Field1 = ObjRecordset("Field1").Value

Field2 = ObjRecordset("Field2").ValueEnd if
