[Borges-users] a unit test?

[wilkes joiner]

After playing around with Borges for the past week, and having played
with Seaside a year or so ago, it would be shame for it to not be as
rock solid as possible.  As a HUGE fan of unit test, it is encouraging
to see this issue being addressed.

Here is a similiar test of the of Controller#call.  It checks each of
the 3 conditional branches of the method.

==BEGIN==
<pre>
require 'test/unit'
require 'Borges'

module Borges; end

class Borges::StateHolder # mock

  attr_accessor :contents
  
  def initialize(*args)
  end
  
end

class Borges::Controller
  attr_reader :continuation
end

class ControllerTest < Test::Unit::TestCase

  def test_PassesControl
    c1 = Borges::Controller.new
    c2 = Borges::Controller.new
    
    class << c2
      def call(c = nil)
        true
      end
    end

    assert c1.call(c2)
  end

  def test_CallSelfSaveContinuation
    c1 = Borges::Controller.new
    assert c1.continuation.nil?
    assert_raises(Borges::RenderNotification) { c1.call }
    assert !c1.continuation.nil?, "continuation should be saved"
  end

  def test_CallSelfDoNotSaveContinuation
    c1 = Borges::Controller.new
    class << c1
      def will_answer?
        false
      end
    end

    assert c1.continuation.nil?
    assert_raises(Borges::RenderNotification) { c1.call }
    assert c1.continuation.nil?, "continuation should not be saved"
  end

end
</pre>
==END==
