EphemeralResponse monkey patch. This patches ephemeralResponse so that request are saved with an associated request number and replayed in order afterwards. The usecase is to support that requests to the same endpoint return different values in different moments.

ephemeral_response_monkey.rb

# Standard ephemeralResponse, although very simple idea, does not respond to our needs
# because it expects that an endpoint will always return the same data
# whether our endpoints return different data because the data is modified in the tests

# We monkey patch fixtures so that data is saved and loaded with a request number
# attached. This allows us to store data for every request
