Free tools are great, because they are always in budget, right? Well, not always, because your time is valuable. You can waste a lot of time if you misuse free tools. However, with commercial tool vendors pounding down your doors, trying to convince you to buy their gee-whiz test tool (often with a gee-whiz price tag to match), you might forget to look at the open-source test tool options available to you. In this talk, drawn from three decades of industry experience including recent consulting work with many clients, Rex will provide some case studies—and the lessons we can learn from them—in successful use of free tools. He’ll also give some cautionary tales of free tool usage gone astray.
