Test Helper

Camille ships an optional response.data helper for Rails integration / request tests. It looks up the endpoint from the current request, validates response.parsed_body against the endpoint's response type, and returns the snake_case body as a HashWithIndifferentAccess so you can use either string or symbol keys in assertions.

In your rails_helper.rb (RSpec) or test_helper.rb (Minitest):

require 'camille/testing'

Then in a test:

get '/products/data'
expect(response.data[:product][:available_stock]).to eq(1)

Since Camille::Controller#render only type checks and converts keys for 200 responses, response.data returns non-200 bodies as-is without validation.

Errors

Situation	Raised
A 200 response body fails the type check	Camille::Testing::ResponseTypeError
The route has no Camille endpoint	Camille::Testing::MissingEndpointError
