Exploratory software testing is a powerful approach, yet widely misunderstood. In some situations, it can be orders of magnitude more productive than scripted testing. All testers practice some form of exploratory testing, unless they simply don’t create tests at all. Yet few of us study this approach, and it doesn't get much respect in our field. This attitude is beginning to change as companies seek ever more agile and cost effective methods of developing software.
