Help with Ruby Koans #6 - What exception has been caught?

I had to put the assert_equal statement into parens to get this one to pass. Must be a bug.

  def test_you_dont_get_null_pointer_errors_when_calling_methods_on_nil
    # What happens when you call a method that doesn't exist.  The
    # following begin/rescue/end code block captures the exception and
    # make some assertions about it.
    begin
      nil.some_method_nil_doesnt_know_about
    rescue Exception => ex
      # What exception has been caught?
      assert_equal(NoMethodError, ex.class)

      # What message was attached to the exception?
      # (HINT: replace __ with part of the error message.)
      assert_match("undefined method", ex.message)
    end
  end

You need to substitute __ with the actual

assert_equal NoMethodError, ex.class 

The answer here is "NoMethodError"

you need the items on either side of the , to be equal, therefore making them both ex.class will do that.

Then you'll need to go on to /__/ Below.
