It probably would have been better for me to code this as an equals one ( == 1) and does not equal one ( != 1). It works as coded, but its not very user-friendly code. Thanks for pointing this out.<BR/><BR/>The potential bug that my daughter noticed does not show up in these results. You'd have to see the test execute or enable screen shot captures for every step to notice it. ... so maybe its not really a bug; or maybe it is a symptom of a bigger problem. Bug or not, it is an unexpected difference.<BR/><BR/>My daughter has not outwitted you. Instead she has demonstrated a sapient power of the human mind: she noticed unexpected behavior that was not part of the explicit model. She didn't even have any written requirements to use for her "testing". She noticed something she did not expect and asked me why it was doing what she saw.<BR/><BR/>Automation will only do what we tell it to do and will only report what we tell it to report. Model-based automation is able to better recover from errors than traditional scripted automation, but it is still limited by the explicit model. Automation can easily miss something that even a child notices.<BR/><BR/>Now that I've seen this potential bug, I can add a validation to my model to look for it. <BR/><BR/>BenBen Simohttp://www.blogger.com/profile/11448600123169359955noreply@blogger.comtag:blogger.com,1999:blog-414482498098790205.post-18319996397486239412007-06-18T09:33:00.000-06:002007-06-18T09:33:00.000-06:00Hi Ben - The initial postings are very helpful, and I'm especially happy to have a copy of the excel sheets that contains the modeling info. <BR/><BR/>Your daughter seems to have outwitted me, though, I don't see a bug in the calulator app from what the model shows me. Arg!<BR/><BR/>I am confused about the "if" statements guarding the detect transitions, they both seem to be able to be true at the same time, because one asks if the value is greater than 0 and the other asks if the value is less than 1, which are not mutually exclusive.<BR/><BR/>GeordieGeordiehttp://www.blogger.com/profile/03935788387957987772noreply@blogger.com
