test suite design with erlang

Are you talking about generating the test cases, i.e. the code
or input to the testing or are you talking about investigating
the test result from a test run?

In other words, what is the "ptl-summary"? A specification for a test
run or the result from one?

Maybe your question is to someone that know rational rose, I don't
know what "bt(basic test tool)" or "PROCESS in bt-toolbox" is all
about.

If the parsing is a problem is to be done off-line and a lot more
complicated than in the small example you sent, why not use Perl for
parsing (if you know Perl) and let it output the summary in a more
easy to read format for Erlang. The summary lines you gave above can
be parsed and tranform to the text representation of a term with

  print "[\n";
  while (<DATA>) {
      chomp;
      # You got to looove Perl ;-)
      print "  [",join(",",map {"\"$_\""} split(/\s*COL\d+:/)),"]";
      print eof(DATA) ? "\n" : ",\n";
  }
  print "].\n";
  
  __DATA__
  ConnectionNoParam COL2:off_hook( ) COL3:Phone1 COL4:Port1 COL5:0
  ConnectionNoParam COL2:dial_tone( ) COL3:Port1 COL4:Phone1 COL5:1

and the output can be read with 

  1> file:consult("r.term").
  {ok,[[["ConnectionNoParam","off_hook( )","Phone1","Port1","0"],
        ["ConnectionNoParam","dial_tone( )","Port1","Phone1","1"]]]}

This will of cause not work if the summary files are huge and you can't
have it all in memory.

A solution in Erlang could be to read line by line, something like the
attached file below. Problem is that parsing code like this often gets
messy. A better solution might be to use the regexp:split() function
and split each line on " COL[0-9]+:".
