Subject: Re: REG: How can we debug a ruby script in unit test classes

Hi,
Using the below method mention the below mail, I was successfully able to run and debug the script.
But when I run unittest class, the flow goes into testcase case class as below.

Testscript 
require "test/unit"
 
class TestSimpleNumber < Test::Unit::TestCase
 
  def test_simple
    assert_equal("abc", "abc" )
    
  end
 
  def test_typecheck
    assert_equal("abc", "abc" )
  end
 
  def test_failure
    assert_equal("abc", "abc" )
  end
 
End



Execution:


C:\ruby>ruby  -rubygems -rdebug  unittest.rb
Debug.rb
Emacs support available.

unittest.rb:1:require "test/unit"
(rdb:1) b 6
Set breakpoint 1 at unittest.rb:6
(rdb:1) cont
Loaded suite unittest
Started
.Breakpoint 1, test_simple at unittest.rb:6
unittest.rb:6:    assert_equal("abc", "abc" )
(rdb:1) n
c:/ruby/lib/ruby/1.8/test/unit/testcase.rb:85:          begin
(rdb:1) n
c:/ruby/lib/ruby/1.8/test/unit/testcase.rb:86:            teardown
(rdb:1) n
c:/ruby/lib/ruby/1.8/test/unit/testcase.rb:94:        result.add_run
(rdb:1) n
c:/ruby/lib/ruby/1.8/test/unit/testcase.rb:95:        yield(FINISHED, name)
(rdb:1) n
c:/ruby/lib/ruby/1.8/test/unit/ui/testrunnermediator.rb:47:            notify_listeners(channel, value)
(rdb:1)


Please help me in this regard.

Thanks,
Anil kumar.
