Rspec tests for custom rails_admin controller actions?

Question

I defined a custom action as a subclass of ailsAdmin::Config::Actions::Base . Under the action I defined a custom controller - register_instance_option :controller

The controller goes through and deletes certain corrupted records and seemed to work fine from my tests. If this was a normal controller I would have written a controller spec for this controller , but I don't know how to write specs for custom rails_admin actions like this.

I took a look at the spec in the rails_admin repository but it doesn't seem to help me much: https://github.com/sferik/rails_admin/blob/master/spec/rails_admin/config/actions/base_spec.rb

I would like to do a normal controller spec where I test posting to the endpoint and then see if a method is called on an object , which the link isn't seeming to do. I couldn't seem to find any useful posts online about using Rspec with custom rails_admin actions .

Answer 1

Here is my setup:

RSpec.describe RailsAdmin::MainController, type: :controller do
 routes { RailsAdmin::Engine.routes }

 describe '#my_custom' do
   subject { get :my_custom, { model_name: 'my_model', id: my_model.id } }

   it "should respond with 302" do
     expect(response.code).to eq("302")
   end
 end
end

Answer 2

I got someone to help me with this. The controller can be tested like so:

describe RailsAdmin::MainController, :type => :controller do

but alone I was having routing issues, even when I added Rails Admin URL helpers to spec_helper.rb. The trick is that when hitting the controller you have to do it like so:

post :custom_rails_admin_route, { :use_route  => :rails_admin }

Tada!
