How to send raw post data in a Rails functional test?

Question

I\'m looking to send raw post data (e.g. unparamaterized JSON) to one of my controllers for testing:

class LegacyOrderUpdateControllerTest < ActionControl

Version for Rails 5:

post :create, body: '{"foo": "bar", "bool": true}'

See here - body string parameter is treated as raw request body.
