I am testing an application with consists of a number virtual environments in several operating systems. One of the operating systems is Windows XPE. I am having image recognization problems due to the fact that “scaling” is turned on so that the screens will fit in a predefined format. This scaling caues the screens not to be displayed exactly the same every time. Sometimes an image is recognized, sometimes not, making the test script unreliable. Re-recording of failing images did not help solve the problem.
I have tried changing the tolerance from 45 to 70. This did not correct the problem. In my previous communications with Support, they said that the 45 setting was best setting and others may settng may give false positives or negatives.
The scaling was turned off to verify it as the source of the problem. It appears to be the source as scripts now would execute successfully.
Other than increasing the tolerance, is there another solution that I can try?
