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

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?
