Hello, everyone We now have automated test coverage for scikit-image: https://coveralls.io/r/scikit-image/scikit-image Most of the newer modules (those that went through rigorous PR review!) did pretty well, but we are still only at 82%. If ever you find yourself with a bit of spare time on your hands, please hunt down some of these corner cases and write tests for them so that we can start making our way towards 100%. Thanks! Stéfan
