Hi Alex,

for this kind of message: "Failed CompareBitmap(body:step 3)  Baseline
image could not be read.  Created image file as a .bad.png."

I'm renaming the created image .bad.png to the expected image to pass. The
problem here is that there's no image, so I think the one created could be
valid.

If some of the things I post here is not right let me know...
