# ## Configuration
#
# You need to set your Firebase Project ID. Additionally you can set your Redis
# server instance in case you don't use Redis defaults.
#
# **WARNING:** Your `project_ids` must be a `Array`.
# ```
# FirebaseIdToken.configure do |config|
#   config.project_ids = ['my-project-id', 'another-project-id']
#   congig.redis = Redis.new(:host => "10.0.1.1", :port => 6380, :db => 15)
# end
# ```
#
# **Defaults**
# + `project_ids` => `[]`
# + `redis` => `Redis.new`
#

  # Method for starting test mode.
  # You can verify with a test certificate or you can use a test private key to verify the token.
  # When using, write it at the beginning of the test.

  #    setup do
  #      FirebaseIdToken.test!
  #    end
  #  end
