As we'll be would be running this time test anyway, we could also confirm the effect of creating the temporary dir for the OfflineItem generator as not all task tests actually need to save a file there. We this proves too expensive (whatever that means) we can reconsider having that initialization on SetUp.

Personally, I think this class works out well as a local variable. It's one extra line in the test, and it gives you more control of when you want the UMA snapshotted.

I agree with that even though I have yet to encounter a case where that is actually needed for a test.

But as this didn't get much traction at all, marking as won't fix.
