Agility

You are not working agile if you do not test your software

Agile working is about bringing people, processes, connectivity and technology, time and place together to find the most appropriate and effective way of working to carry out a particular task

One of those things is the tool selection.

Why may one way be so much better then the others? Various tools have different advantages and disadvantages, because having various advantages and disadvantages is a natural consequence of doing things differently and most of the time one advantage may not be important at all to achieve the goal, but is actually one of the main selling points of a tool.
