Here goes a good online companion for testing. Its worth using it.
The product, named TestersDesk, is the world's first online tooling companion from ValueMinds (www.valueminds.com). It delivers widely needed tester-centric features such as generation of test data files, test input helpers that aid in driving input data during testing, security testing aids, web data generators.
No, I am not associated with this company. (I wish I could :-)). The good thing I found in here is that, we can easily create and maintain the test data files and drive test inputs. Apart from this it features lot many other useful tools which are readily available for the test engineer to use.
