Hi Max,

Here is the solution to the problem, finally.


I looked into the source and it appears that the framework is setting up the
tests so that a prepared result and the result are observing each other.
These objects do not know about the class you are testing as needing
observing.  This is the override of setup_assert that runit TestCase uses
internally to notify the observers when an assert is run.


Instead of including RUNIT::Assert in the tested class, pass a reference to
the test class into the verify method and call it back to assert and the
asserts will be counted:

class MockNoteHandler
# do not include assert

def initialize
subscribeForNotes(self)
end

def onNewNote(sender, event, data)
@actual_sender = sender
@actual_data = data
end

def expectData(sender, data)
@sender = sender
@data = data
end

def verify(testCase)
testCase.assert(@actual_data == @data)
testCase.assert(@actual_sender == @sender)
end
end

class NotterTest < RUNIT::TestCase
include Notter

def setup
@mh = MockNoteHandler.new
end

def test_simple_note
assert_exception(RuntimeError) { note() }
@mh.expectData('NotterTest', 'greets')
note 'greets'
@mh.verify(self) # pass reference to self
end
end

if $0 == __FILE__
require 'runit/cui/testrunner'
RUNIT::CUI::TestRunner.run(NotterTest.suite)
end
