This type of testing is not new. I used something like this 8 years ago. There are pros and cons to screenshot testing... the biggest downside is that it catches EVERYTHING.

If the developers change anything in these modules, all of your screenshots will break... and if the developers do this constantly, your tests are basically useless.
