last_env.rb

# Should be used with CapybaraInterceptor, see capybara_interceptor.rb in this directory.
#
# Gives access to last_session, last_env in feature specs. Handy for debugging intermittent
# failures. Reading last_session, last_env etc. in a feature spec isn't usually needed however,
# so consider aiming for minimal usage of this.
