At present we're only returning Vary response headers when we get a B variant. We want to do this all the time or it's confusing for Fastly to know how to cache.
I've added a test that ensures (using the
with_variant
helper) that the header is being set correctly, and also checks for analytics set up.It's trickier to assert things about the template because slimmer's testing is harder to figure out right now, but it'd be useful to add these at some point too. :-)
