OGC compliance suites are examples of functional tests, they assume the
server has a given data set ready to be served, make requests, check the
results for a set of conditions that must be met.

However, all the tests suites rely on tests that are not visual, the WMS one
is the only one that has a few visual tests and it actually asks the human
running the test to compare the images.

If you have exemplars of how a map should look like you can use
pdiff (perceptual diff) to compare the expected image with the one actually
returned. I believe MapServer automated tests are done that way.
