# == Test adapter for Action Cable
#
# The test adapter should be used only in testing. Along with
# <tt>ActionCable::TestHelper</tt> it makes a great tool to test your Rails application.
#
# To use the test adapter set +adapter+ value to +test+ in your +config/cable.yml+ file.
#
# NOTE: Test adapter extends the <tt>ActionCable::SubscriptionsAdapter::Async</tt> adapter,
# so it could be used in system tests too.
