HI  
I am having a list. I want to select a number in random from that list?  
which command I can use it for doing this?

For example :

$ie.row(:class =\>“bgTableAltColors”,:index  
=\>“4”).cell(:class,“padTableRightBorder”).select\_list(:class,“Formelement”).option(:text,“Test  
Automation - Scripting”).select

here instead of “Test automation -scripting” I want to select a option  
in random.  
How can i do it ?

Please help.  
Thanks in advance.

You can do it like this:

list.sort\_by{rand}.first

To get a random element from an array

some\_array[rand(some\_array.size)]
