I did that because the test is about the bit after the move, not the move itself, so a failing move is closer to a setup failure. I thought it was better to stop there and let whoever runs it check their environment before running the rest. But having gone through the file's history, I see the direction has been to skip or fail just that one test and keep the rest running. I'll change it in v4. Thanks for the review! Donggeun
