  • State changed from “new” to “open”
  • Importance changed from “” to “Low”

  I was able to reproduce this on Rails 3.0

  I also found the following two tests produce strange output.

  Two additional tests:

    def test_initialization_count_again
      assert_equal 1, initialized_count
    end
  
    def test_initialization_count_after_foo
      foo
      assert_equal 1, initialized_count
    end
  

  Output:

    1) Failure:
  test_initialization_count(NinjasHelperTest) [test/unit/helpers/ninjas_helper_test.rb:5]:
  <1> expected but was
  <nil>.
  
    2) Failure:
  test_initialization_count_after_foo(NinjasHelperTest) [test/unit/helpers/ninjas_helper_test.rb:14]:
  <1> expected but was
  <2>.
  
  3 tests, 3 assertions, 2 failures, 0 errors, 0 skips
  

  Note that the original test fails, however the same test repeated passes and also the method foo has access to @initialized_count (set to 1).

  Could this be the result of some kind of lazy loading? I haven't yet dug into the Rails source yet but I thought I should report my findings if somebody else finds them helpful.

  @rohit - I'm confused about the foo method in your example. Can you post it (and tell me where it lives)?

  Just for completeness...

  @David, sorry for not including the module code. The module with the additional foo method is as follows:

  module NinjasHelper
    attr_accessor   :initialized_count
    def initialize( *args, &block )
      super *args, &block
  
      @initialized_count    ||= 0
      @initialized_count    +=  1
    end
  
    def foo
      @initialized_count ||= 0
      @initialized_count += 1
    end
  end
  

  The tests and result of running tests was same as above.
