Wie man Daten in Rack::Test POSTet

Question

Ich habe Probleme zu verstehen, wie man mit Rack::Test arbeitet, das Problem, das ich habe, ist mit POST. Dies sind die Klassen und der Fehler:

hellotesting.rb

require 'sinatra'

post '/foo' do 
    "Hello #{params[:name]}."
end 

Das ist der Test:

require 'hellotesting'
require 'test/unit'
require 'rack/test'

set :environment, :test

class HelloWorldTest < Test::Unit::TestCase
    def test_it_says_hello_to_you
        browser = Rack::Test::Session.new(Rack::MockSession.new(Sinatra::Application))
    post "/foo", "name" => "Bryan"
        assert browser.last_response.ok?
        assert_equal 'Hello Bryan', browser.last_response.body
   end
end

Und die Ausgabe:

1) Error:
test_it_says_hello_to_you(HelloWorldTest):
ArgumentError: wrong number of arguments (1 for 0)
