Error Handling in UFT - Contd...

See the basic post if you didn't.

Now you wonder, is there a way to implement inside our code.
Here we go;

Browser("myapp").Page("myPage").WebEdit("mytext1").Set "someText1"
If Err.Number <> 0 Then
  Reporter.ReportEvent micFail, "some step", "some description"
  Err.Clear
End If
'after handling the error, continue to next step
Browser("myapp").Page("myPage").WebEdit("mytext2").Set "someText2"
If Err.Number <> 0 Then
  Reporter.ReportEvent micFail, "some step", "some description"
  Err.Clear
End If

So the complexity is, we need to add the error check block after each step which is not good.So what can we do better is;

Function CheckForError
  Environment.Value("IsError") = False

  If Err.Number <> 0 Then
    Reporter.ReportEvent micFail, "some step", "some description"
    Environment.Value("IsError") = True
  End If

  CheckError = Environment.Value("IsError")

End Function

'##########################################################
' ---------------- COMPONENTS ----------------------------
'##########################################################

Function COMPONENT_1
   Browser("myapp").Page("myPage").WebEdit("mytext1").Set "someText1"
   If CheckForError Then Exit Function

   Browser("myapp").Page("myPage").WebEdit("mytext2").Set "someText2"

   If CheckForError Then Exit Function
End Function

From your Driver Script, you can check for Environment.Value("IsError") after executing each keyword and take decision. What else we can do still to avoid even these calls but need this error handling.

Using Recovery Scenario:
You can create a Recovery Scenario with the event "Test Run Error" and add this CheckError function as part of recovery function. Now it should call and check for errors, do the recovery steps described as part of your function whenever an error happens.

Also you can write some common function to do all events with error handling like this and use.


Function Simulate(objUICtrl, strValue)
    On Error Resume Next

    Select UCase(objUICtrl.GetROProperty("micClass"))
           Case "WEBEDIT":
                     objUICtrl.Set Trim(strValue)
           Case "WEBLIST":
                     objUICtrl.Select Trim(strValue)
           Case "WEBELEMENT":
                     objUICtrl.Type Trim(strValue)
    End Select

   If Err.Number <> 0 Then
        'Your recovery steps...
   End If
   Err.Clear 'always safety
End Function
RegisterUserFunc "WebEdit", "Set", "Simulate", True
RegisterUserFunc "WebList", "Select", "Simulate", True
RegisterUserFunc "WebElement", "Type", "Simulate", True
Usage:
Browser("myApp").Page("myPage").WebEdit("someText").Simulate "someValue"
Browser("myApp").Page("myPage").WebList("someList").Simulate "someValue"

Change IE Browser ZOOM settings

Lot of UI automation testers could have faced this problem as we could change the zoom settings while operating manually for our convenience and forgot to reset to 100%.
But our QTP and some other related tools would operate the browser perfectly if browser zoom is 100%. So wee need to change the zoom before start to run the scripts. Its better to have a code snippet in our framework to change this zoom setting right?
Here we go...

1. We can simply change the Registry values before Invoking IE
Function ChangeRegistry Dim objShell Set objShell = CreateObject("WScript.Shell")  objShell.RegWrite "HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Zoom\ZoomFactor", "100000", "REG_DWORD" Set objShell = Nothing EndFunction This option is very useful. But in real time, lot of customers could have restricted write access to windows registry. So we can try other options.

2. Use IE COM object and Change Settings
Function ChangeIEZoom Dim intZoomLevel, objIE  intZoo…

QTP - Object Identification - Prerequesties

While starting a new project or proof of concept or after new QTP installation, we would face the issue in identifying objects as QTP built objects like WinList, WebEdit, etc.; instead everything will be identified as WinObject.

Here are some steps to ensure you did the environment setup RIGHT before start automating.
Did you enabled required Add-ins only while launchingDid you selected "Record >> Record and Run Settings" - This should be based on what type of application you are working with
Windows app - Windows >> Record and run test on any windows applications. Web app - Web >> Record and run test on any open browser.
Did you tried to launch UFT/QTP and then AUT.If its web, ensure browser zoom level set to 100%Try disabling the protected mode in IE for web.Launch UFT and AUT using RUN AS ADMINISTRATORAlso see the Object Identification Methods if you are interested.

Run JavaScript from QTP

Yeah, You can run your pure JavaScript from QTP using RunScript method. Lot of times, we are in need of firing events or simulating actions on web page which is not supported by QTP. At that time, you can use your direct DOM methods and directly execute your script on the web page from QTP like,
Dim MyPage, SearchBox Set MyPage = Browser("title:=Google").Page("title:=Google") Set SearchBox = MyPage.RunScript("document.getElementsByName('q')(0);") SearchBox.Value="testing"
'if objects available in frames, Set SearchBox = MyPage.RunScript("document.frames(4).document.getElementsByName('q')(0);")
'OR
Set objFrame = Browser("title:=Google").Page("title:=Google").Frame("title:=something")
objFrame.RunScript("document.getElementsByName('q')(0);") Also, you can execute by obtaining actual browser window object if you have IE app like, Dim IEApp Set IEApp = CreateObject("Internet…
