Setting session variables in an RSpec Rails request spec

Setting session variables in an RSpec Rails request spec

You are writing a spec with type: :request, i.e. an integration spec instead of a controller spec. Integration specs are wrappers around Rails' ActionDispatch::IntegrationTest class.

### Enable Echo/Noise-Cancellation
load-module module-echo-cancel use_master_format=1 aec_method=webrtc aec_args="analog_gain_control=0\ digital_gain_control=1" source_name=echoCancel_source sink_name=echoCancel_sink
set-default-source echoCancel_source
set-default-sink echoCancel_sink

cipher.key = Digest::SHA1.hexdigest key
s = cipher.update(self) + cipher.final
s.unpack('H*')[0].upcase
