Seriously dude, quit thread jacking and post in the section related to open positions.

Hi Thanvi,
You can create a test suite for executing 10 test cases out of 100. I am assuming that you are using eclipse for wrinting test cases. You need to create a xml file. Let's say "test.xml" and add all the test cases (classes) in to it.
For example -

Code:

<!DOCTYPE suite SYSTEM "[url=http://testng.org/testng-1.0.dtd]http://testng.org/testng-1.0.dtd[/url]">
<suite
name="TestSuite">
<test verbose="2" name="com.companyname.sanitysuite"
annotations="JDK">
<classes>
<class
name="com.companyname.sanitysuite.SearchProduct"/>
<class
name="com.companyname.sanitysuite.EditProduct"/>
<class
name="com.companyname.sanitysuite.AddSupplier"/>
</classes>
</test>
</suite>

Once you will add your test cases in to it. click right mouse on file -> Run as -> Test Ng.
Hope this will help.
Thanks,
