tdd - Rails test post content

Question

Rails 6

how to post header AND body in rails test?

considering tipps like this

Rails test/integration

require 'test_helper'

class DataTest < ActionDispatch::IntegrationTest

  test "Post Profiles" do
    post "/candy/user/profiles", {headers: {:authorization => @session[:authorization]}}, {'RAW_POST_DATA' => 'something'}
  end

end

Result

DataTest#test_Post_Profiles:
ArgumentError: wrong number of arguments (given 3, expected 1)
    test/integration/candy/data_test.rb:31:in `block in <class:DataTest>'

that too didnt help could not see any sent body in controller by request.raw_post or request.body.read

def raw_post(action, params, body)
    @request.env['RAW_POST_DATA'] = body
    response = post(action, params)
    @request.env.delete('RAW_POST_DATA')
    response
end

Answer 1

Raw post is request body, in modern rails you can pass a string for params parameter:

  post "/candy/user/profiles", headers: {authorization: @session[:authorization]}, params: 'something'
