Subject: [test-unit-users-en:00002] Question about assert_kind_of
Message-ID: <6037b70c0905261316j131be9bay52320295383cdeab@mail.gmail.com>

Hi,

Ruby 1.8.6 p368
test-unit 2.0.2

Why does this fail?

require 'rubygems'
gem 'test-unit'
require 'test/unit'

module Foo
   class BarError < StandardError; end
end

class TC_Test < Test::Unit::TestCase
   def test_class
      assert_kind_of(StandardError, Foo::BarError)
   end
end

Result:


  1) Failure:
test_class(TC_Test) [test_test.rb:11]:
<Foo::BarError>
expected to be kind_of?
<StandardError> but was
<Class>.

Regards,

Dan

Because Foo::BarError.kind_of?(StandardError) returns false.


  assert_kind_of(StandardError, Foo::BarError.new)

will be passed.
