You can also mark them NeedsRebaseline.

[chrishtr, 2016/10/06 17:11:08]

I can't do that without breaking SPv1 expectations or adding them to
virtual/spv2, no?

[Xianzhu, 2016/10/06 17:26:19]

The NeedsRebaseline won't cause real rebaseline until the expectations are
merged into the main TestExpectations. It seems better than Failure because it
states the actual result is valid, while Failure states we need to fix it.

Good point. Done.
