Could the snapshot.check throw an exception if it fails?

Hi there, I have data I want to do a regression test on. And when the check fails I want to plot the data for visual inspection. I attempted this with a try/cath syntax and then realized that snapshot.check does not raise an exception. I believe this may be because it only registers the data and checks it later after the test has run. It would be nice if I could somehow handle the case of failure to provide a visual way to inspect the data.
