Testing Rails Metal/Rack with RSpec?

Question

Say I have a Metal class named Preview. How do I test it with RSpec?

When I try:

require 'spec_helper'

describe Preview do

  it "should return the posted content" do
    post "/preview", :content => "*title*"
    response.body.should == "*title*"
  end

end

I get:

undefined method `post' for #<ActiveSupport::TestCase::Subclass_1:0x1058b3098>

It seems that RSpec doesn't load up the :post method if the test isn't explicitly for a Controller. I've tried specifying :type => :controller to no avail.

Answer 1

I think it's better to test with rack/test

Answer 2

Matt - rspec has integration specs that wrap rails integration tests (which go through rack). Just put that spec in ./spec/integration/preview_spec.rb.
