# Puffing Billy caches external requests made by JS calls

# in spec/support/request/cache.
#
# Makes test faster since we hit Google fonts and some Stripe
# calls via the DOM.
#
# Specs that hit the Stripe checkout form are tagged as
# :stripe_checkout_form so they can be ignored in CI and
# only run as needed. These requests have numerous chained calls
# with cache-busting JSONP and slow down the build significantly.
# Let's assume Stripe tests their forms - we don't need to do that
# for them.
