This is the command line that ctest executed to run this particular test.

This says the test failed because it produced an image that doesn't
look like it is supposed to.

These are where the images (correct, difference, and test result) are
stored (ie under Testing/Temporary/buildName). You could look at the
two images and decide if the problem is worth debugging further.

What other tests are failing?
