It's a bit hard to make sense of this commit: does it introduce new
tests? Does it refactor existing tests? Does it change the test setup?
It seems to be a mixture of all of these, which makes it hard to see
what the actual change is.

I'd propose to split up this commit into multiple ones: one that
introduces `restore_upstream()`, one that adapts the test data, and one
that introduces new tests.
