What are the languages used in software testing tools?
Well, software testing doesn't needs any language! Languages are used only while software engineering!
As I've said, no language is used for any testing purpose bro! I must ask : Who said you this? These languages are used in building any executable set of codes as per ones needs/desire!
Usually you do the testing in the language you have written the code in. For gui tests there is special software like Test Complete or others.
I want to ask that perl, python are used mostly in testing of software or any other like that?
