QTP tips

上一篇 / 下一篇 2008-04-17 21:26:59 / 个人分类：QTP

1) How to add a constant number in a datatable?
yE5y5N.Tx.k8~0This is more to do with MS excel then QTP!! but useful to know because at times it becomes frustrating to the novices.
Just append ' to the number
Ex: if you wish to enter 1234567 in datatable then write it as '1234567

2) How can i check if a parameter exists in DataTable or not?
The best way would be to use the below code:
on error resume next
val=DataTable("ParamName",dtGlobalSheet)
if err.number<> 0 then
'Parameter does not exist
else
'Parameter exists
end if

3) How can i check if a checkpoint passes or not?
chk_PassFail = Browser(...).Page(...).WebEdit(...).Check (Checkpoint("Check1"))
if chk_PassFail then
MsgBox "Check Point passed"
else MsgBox "Check Point failed"
end if

4) My test fails due to checkpoint failing, Can i validate a checkpoint without my test failing due to checpoint failure?
l#D!zaLx0Reporter.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 then
MsgBox "Check Point passed"
else
MsgBox "Check Point failed"
end if

5) 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 scrīpting. 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.

6) 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 Action only. If the functionality is not about any automation scrīpt i.e. a function like getting a string between to specific characters, now this is something not specific to QTP and can be done on pure VB scrīpt, so this should be done in a function and not an action. Code specific to QTP can also be put into an function using DP. Decision of using function/action depends on what any one would be comfortable using in a given situation.

7) When to use a Recovery Scenario and when to us on error resume next?51Testing软件测试网 O.gj9_+Co
Recovery scenarios are used when you cannot predict at what step the error can occur or when you know that error won't occur in your QTP scrīpt 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.descrīption to get more details about the error.

8) How to use environment variable?
A simple defintion could be... it is a variable which can be used across the reusable actions and is not limited to one reusable action.
There are two types of environment variables:
1. User-defined
2. Built-in
We can retrieve the value of any environment variable. But we can set the value of onlyuser-definedenvironment variables.

To set the value of a user-defined environment variable:
Environment (VariableName) = NewValue

To retrieve the value of a loaded environment variable:
CurrValue = Environment (VariableName)

Example51Testing软件测试网&}I:zq;\ y7}
The following example creates a new internal user-defined variable named MyVariable with a value of 10, and then retrieves the variable value and stores it in the MyValue variable.

Environment.Value("MyVariable")=10
MyValue=Environment.Value("MyVariable")

9) What are the files and subfolders of a QuickTest Professional test?51Testing软件测试网LW:\$o@F
The files and folders hold binary and text data that are required for the test to run successfully.
Y4\tm8I0The following table provides a descrīption, the type, and comments regarding the files that make up a QuickTest Professional test.

10) How to rename a checkpoint (QTP 9.0)?
,]&hWCKg0Example:
WKihK?^G0Window("Notepad").WinEditor("Edit").Check CheckPoint("Edit")
In the above example, the user would like to change the name of the CheckPoint object from "Edit" to something more meaningful.
[%g"P$dXi{/|5udK0Note:51Testing软件测试网K(kQ{:I,G/|
This functionality is new to QuickTest Professional 9.0.This is not available for QTP 8.2 and below.51Testing软件测试网$si,g8Wjq[
1. Right-click on the Checkpoint step in the Keyword View or on the Checkpoint object in Expert View.51Testing软件测试网%K_)IJ'_}
2. Select "Checkpoint Properties" from the pop-up menu.
3. In the Name field, enter the new checkpoint name.
TE:fO&z!fxW04. Click. The name of the checkpoint object will be updated within the scrīpt.
-{{O"V@NG0W1d0Example:51Testing软件测试网`#?z._x:t4I
Window("Notepad").WinEditor("Edit").Check CheckPoint("NewCheckPointName")
Note:
C[H:N.na~vjZ0{0You must use the QuickTest Professional user interface to change the name of the checkpoint. If you manually change the name of the checkpoint in the scrīpt, QuickTest Professional will generate an error during replay. The error message will be similar to the following:

"The "" CheckPoint object was not found in the Object Repository. Check the Object Repository to confirm that the object exists or to find the correct name for the object."

The CheckPoint object is not a visible object within the object repository, so if you manually modify the name, you may need to recreate the checkpoint to resolve the error.

16) The follow situation need to use Parentheses.

When programming in VBscrīpt, it is important that you follow the rules for using or not using parentheses () in your statements.

You must use parentheses around method arguments if you are calling a method that returns a value and you are using the return value. For example, use parentheses around method arguments if you are returning a value to a variable, if you are using the method in anIfstatement, or if you are using theCallkeyword to call an action. You also need to add parentheses around the name of a checkpoint if you want to retrieve its return value.51Testing软件测试网1A?3[5K2FRam

Tip: If you receive anExpected end of statementerror message when running a step in your test, it may indicate that you need to add parentheses around the arguments of the step's method.

Following are several examples showing when to use or not use parentheses.

The following example requires parentheses around method arguments, since it returns a value to a variable.

Set WebEditObj = Browser("Mercury Tours").Page("Method of Payment").WebTable("FirstName").ChildItem (8, 2, "WebEdit", 0)

WebEditObj.Set "Example"

The following example requires parentheses around method arguments, sinceCallis being used.

Call RunAction("BookFlight", oneIteration)

The following example requires parentheses around method arguments, since the method is used in anIfstatement.51Testing软件测试网 M mRR?0{

If Browser("index").Page("index").Link("All kind of").WaitProperty("attribute/readyState", "complete", 4) Then Browser("index").Page("index").Link("All kind of").Click

The following example requires parentheses around method arguments, since it returns the value of the checkpoint.

a = Browser("MyBrowser").Page("MyPage").Check (CheckPoint("MyProperty"))

The following example does not require parentheses around theClickmethod arguments, since it does not return a value.

Browser("Mercury Tours").Page("Method of Payment").WebTable("FirstName").Click 3,451Testing软件测试网X"zv;zq~

17) Encrypts a string.51Testing软件测试网,XeYJ(e"g#e

In the following example, a password is taken from a database and encrypted using theEncryptmethod, and then placed in the password edit box using theSetSecuremethod.51Testing软件测试网 zu z7^TA&M

pwd = "GetPasswordfromSomewhere"

e_pwd = Crypt.Encrypt(pwd)

Browser("dfgd").Dialog("pass").WinEdit("pwd").SetSecure e_pwd51Testing软件测试网?5Y7f!}:hliR

18) Environment object example:51Testing软件测试网m'U;pIjR

The following example uses the ExternalFileName property to check whether an environment variable file is loaded, and if not, loads a specific file and then displays one of the values from the file.51Testing软件测试网f!kv#X Ya8T

'Check if an External Environment file is loaded and if not, load it.

fileName = Environment.ExternalFileName51Testing软件测试网 |V3w*?:ci s

If (fileName = "") Then

Environment.LoadFromFile("C:\Environment.xml")

End If51Testing软件测试网 H9RP2@ T3n

'display value of one of the Environment variables from the External file

msgbox Environment("MyVarName")
