Debugging in Test::Unit::TestCases

ruby-talk
1

Hi,

This is no biggie but just wanted to points out
a difference between RUnit and Test::Unit that I find a bit annoying

In the latter I can’t seem to do

ruby -r debug test_case.rb

then set a breakpoint in a test method in a TestCase in test_case.rb and
the let it run up to the breakpoint. If I don’t remember incorrectly
RUnit had no troubles with this?

Or have I missed something?

Its no biggie but just wanted to point that out.

Thanks to Nathaniel and others working on unit testing frameworks,

Yeah, its somewhat old

$ ruby -v
ruby 1.8.0 (2003-02-22) [i386-mingw32]

and second to latest Test::Unit. Hmm, seems I draw some erroneous
conclusions there, seems I can’t set any breakpoints at all. I thought it
had something to do with Test::Unit.

I’ll update to latest versions and see if that’ll fix it.

Thanks,

Robert

Well, I've this in unit.rb

at_exit {
  # We can't debug tests run with at_exit unless we add the following:
  set_trace_func DEBUGGER__.context.method(:trace_func).to_proc if (defined? DEBUGGER__)

I don’t use at_exit in this one but it still doesn’t work

$ ruby -v

feldt@KLABADA /tmp/development/aardappel/trunk
$ ruby -r debug -Ilib test/test_tree.rb
Debug.rb
Emacs support available.

Test::Unit *use* at_exit
