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

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
