Undefined method `add_assertion' for nil:NilClass

ruby-talk

I found my problem.

I added following two lines to my code in my include section, which is at
the begin of my main program:

    require 'test/unit/assertions'
    include Test::Unit::Assertions

This solved all my assert problems in my code.

I started with ruby about 6 weeks ago. So I am pretty new. The code I have
contains out of 4 files and works only with a specific underlying
application, which I manipulate through the code. Maybe I am misuderstanding
the use of assertions. I thought that assertions help raising errors. I
don't want to run a Unittest. So maybe my approach is wrong?
I removee < Test::Unit::TestCase

Now I get:
TEST FAILED.undefined method `assert' for #<WebAC::BPUtils:0x2c2e270>

My code:
  #Includes
    require 'test/unit/assertions'
    require 'test/unit'

  # more code
  $clsBPUtils = BPUtils.new
  # more code

  class BPUtils
    require 'test/unit/assertions'
    
    def initialize
        # empty
    end

    def bpVerifyPopupWindowOpen( ieCont, verify)
      begin
    assert( ieCont.contains_text( verify) )
    puts("TEST PASSED. Found test string 'Programming Ruby' ")
   rescue => e
         puts("TEST FAILED." + e.message + "\n" + e.backtrace.join("\n"))
   end
end

Hello,

I tried to use assertion's the first time in my code and had
absolutely now success. I always get following error:

TEST FAILED.undefined method `add_assertion' for nil:NilClass
c:/ruby/lib/ruby/1.8/test/unit/testcase.rb:115:in `add_assertion'
c:/ruby/lib/ruby/1.8/test/unit/assertions.rb:353:in `_wrap_assertion'
c:/ruby/lib/ruby/1.8/test/unit/assertions.rb:38:in `assert'
./utils.rb:1376:in `bpVerifyOnPage'

Here is a code snipe (verify is a string that is passed to a function):

The if statement works fine. The assert gives me trouble. Why? What is
wrong? What is the nil class?
I also tried assert(true), assert_equal("1234","1234") with the same
result

The code you're posted doesn't compile, so it can't be a real example of
what's not working. Can you provide a real example?
