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：

您可能需要将Rack :: Test mixins包含在各个类中。我主要使用RSpec，它不使用类，但使用Ruby的include的专用变体来提取额外的功能。您可能想尝试在include Rack::Test::Methods案例类定义中加入HelloWorldTest。 Sinatra的testing提供了更多有关使用Rack::Test进行测试的信息。
