We do that for failures that actually relate to what's being tested, but
these lines are only setup, and each depends on the one before: if any
fail, all the ones after it are certain to.
I think I might change it to not do the actual tests if we can't do the
setup, though!
I'll give v8 a quick sanity check: more in about an hour.
