Fluent Interface Design Pattern in Automation Testing

Recently, I was going through some of the design patterns in Java by reading the book Head First Design Patterns by Eric Freeman, Elisabeth Robson, Bert Bates, and Kathy Sierra.

Putting Together a Testing Team

As part of one of my consulting efforts, I worked with a mid-sized company that was looking to move toward a more agile manner of developing software. As with any shift in work style, there is some bewilderment and, for some, considerable anxiety.
