Q. What about the poor people who need guidance on how to test?
My (free) offerings to those poor people include those just above. Those poor people are welcome to use these suggestions and to investigate the alternatives that anyone else offers. That may be harder than referring to an ISO standard and appealing to its authority. (It may be considerably easier, too.) But my first piece of guidance on how to test is this: learn about testing, and learn how to test, through study and practice. I argue that ISO 29119 will not help you with that.
Really, really good write up on what ISO 29119 is all about, and more importantly, why you should be against it. I encourage everyone to head over and check out Michael’s page, and then go sign the petition.
