更简单的方法来测试我的简单Rack应用程序？

Question

i have a Rack app like this:

app = Rack::Builder.new do

    map '/' do
        # ...
    end

    map '/edit' do
        # ...
    end

end.to_app

How would i test it without long-tail installation/setup/learn process.

RSpec and minitest are really great, but i do not really want to learn nor setup them.

Is there something i cat just plug in and write/run tests right away in plain Ruby?

I want to write tests as simple as i wrote the app above, without advanced techniques and gotchas.

In KISS I Trust!

Answer 1

Simplest? Use Rack::Test with Test::Unit . gem install rack-test and run with ruby filename.rb

require "test/unit"
require "rack/test"

class AppTest < Test::Unit::TestCase
  include Rack::Test::Methods

  def app
    Rack::Builder.new do
      map '/' do
        run Proc.new {|env| [200, {'Content-Type' => 'text/html'}, "foo"] }
      end

      map '/edit' do
        # ...
      end
    end.to_app
  end

  def test_index
    get "/"
    assert last_response.ok?
  end
end

Update : RSpec style requested - gem install rspec ; run with rspec filename.rb

require 'rspec'
require 'rack/test'

describe 'the app' do
  include Rack::Test::Methods

  def app
    Rack::Builder.new do
      map '/' do
        run Proc.new {|env| [200, {'Content-Type' => 'text/html'}, "foo"] }
      end

      map '/edit' do
        # ...
      end
    end.to_app
  end

  it 'says foo' do
    get '/'
    last_response.should be_ok
    last_response.body.should == 'foo'
  end
end

Answer 2

you can try Specular + Sonar bundle.

Specular is for writing tests anywhere you need them.

Sonar is a mock "browser" that communicate to your app, just like rack-test does, but with some unique features and simpler workflow.

Using them is as simple as:

...
app.to_app

Spec.new do
  include Sonar
  app(app)

  get
  check(last_response.status) == 200
  # etc...
end
puts Specular.run

so you put your specs right beside your app and write tests quickly in plain Ruby, without having to learn anything.

see the full example running at CIBox

(if it does not run automatically, click Run button)

PS: writing Rack apps this way is kinda a pain.

You can try a mapper, like Appetite one.

so your app may look like this:

class App < Appetite
  map :/

  def index
    'index'
  end

  def edit
    'edit'
  end
end

see the same example but with app built by Appetite here

您可以使用机架测试，但这又需要使用minitest / unit测试，但这是测试Rack应用程序的最常用方法。
