redirect_to matcher

The redirect_to matcher is used to specify that a request redirects to a given template or action. It delegates to assert_redirected_to.

It is available in controller specs (spec/controllers) and request specs (spec/requests).

Using redirect_to with four possible options

Given a file named “spec/controllers/widgetscontrollerspec.rb” with:

require "rails_helper"

RSpec.describe WidgetsController , type: :controller do

  describe "#create" do
    subject { post :create, :params => { :widget => { :name => "Foo" } } }

    it "redirects to widget_url(@widget)" do
      expect(subject).to redirect_to(widget_url(assigns(:widget)))
    end

    it "redirects_to :action => :show" do
      expect(subject).to redirect_to :action => :show,
                                     :id => assigns(:widget).id
    end

    it "redirects_to(@widget)" do
      expect(subject).to redirect_to(assigns(:widget))
    end

    it "redirects_to /widgets/:id" do
      expect(subject).to redirect_to("/widgets/#{assigns(:widget).id}")
    end
  end
end

When I run rspec spec/controllers/widgets_controller_spec.rb

Then the examples should all pass.
