Selenium Grid with TestNG


Hi all,
Here I want to share some information on "How to run selenium tests in parallel using Grid".

Steps:

1.     Keep ready the tests and TestNG.xml file by including tests to be run.
2.     Launch the Grid using "ant launch-hub"
3.     Then, launch how many RC instances you want to run on different environments like,  "ant launch-remote-control"
1.     You should use parameter -DhubURL=yourHubURL. Here yourHubURL is the machine address in which you launched Grid Hub.
2.     then you can use parameters -Dport, -Denvironment, -Dhost to launch different RCs.
4.     So now, Hub and RC instances are running. To see the running instances, goto http://localhost:4444/console
5.     After this, you have to make test multiplication for the purpose of making each instance to run a test.Because all instances will not share a single test.
So make the testng.xml file as below. I have a test

<suite name="Suite1"  parallel="tests" thread-count="2">
<test name="TestPlans1" preserve-order="false" > 
<parameter name="Browser" value="*firefox">
    <classes> 
      <class name="TestPlans.TestPlan_1"> 
        <methods> 
        </methods> 
      </class> 
      <class name="TestPlans.TestPlan_2"> 
        <methods> 
          <include name="TestCase_1"/> 
          <include name="TestCase_2"/>
        </methods> 
      </class> 
    </classes> 
  </test> 

This is my actual XML file. But I created this copy with another test name inside only my browser is changed. So it will run separately on different specified browsers.

<test name="TestPlans2" preserve-order="false" > 
<parameter name="Browser" value="*iehta">
    <classes> 
      <class name="TestPlans.TestPlan_1"> 
        <methods>
        </methods> 
      </class> 
      <class name="TestPlans.TestPlan_2"> 
        <methods> 
          <include name="TestCase_1"/> 
          <include name="TestCase_2"/>
        </methods> 
      </class> 
    </classes> 
  </test> 

6. Now go and Run the TestNG test from Eclipse. Thats all.

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…
