ruby - 如何在 Rack::Test 中发布数据

Question

我在理解如何使用 Rack::Test 时遇到问题，我遇到的问题是 POST。这是类和错误:

hellotesting.rb

require 'sinatra'

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

这是测试:

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

输出:

1) Error:
test_it_says_hello_to_you(HelloWorldTest):

您可能需要将 Rack::Test 混入包含到您的个人类中。我主要使用 RSpec，它不使用类，但使用 Ruby 的 include 的特殊变体来引入额外的功能。您可能想尝试将 include Rack::Test::Methods 放入您的 HelloWorldTest 案例类定义中。 Sinatra 的 testing有更多关于使用 Rack::Test 进行测试的信息。
