The free sample, or test drive, is a very powerful tool in the sales cycle. Until recently it simply was not practical for software. Now some companies have begun to offer thirty-day trials of their software. Codign has been offering a trial version of its code testing plug-in, CoView.
I will be interested in watching how this approach works. Much of the cost of software is associated with the installation and training requirements, so a free trial only solves part of the problem. Still, I think free trials will become part of almost every sales cycle.
Testing is important, automatically generating JUnit tests is magical
