simpler way to test my simple Rack app? - ruby

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

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

You could use rack-test but that again entails using minitest/unit test but is the most common way testing Rack apps.
