Rails - Sep 2005 - Re: Rails Digest, Vol 12, Issue 343

I asked myself this question today while debugging a test. How the
heck do I connect to a breakpointer session from a unit test?

Stephen''s suggestion is a good workaround (type successive lines), but
I haven''t heard anyone address the question: how do you get a REAL
Ruby debugging session going in a Rails test!  Breakpoint during a
test drops you into an IRB session -- not a DRB debugger session!!!
The breakpointer session just sits there.

Don''t get me wrong, I''ve been finding IRB incredibly useful in
my unit
tests when I can''t figure out a failure just by looking at the code,
but the question remains, how to debug?

I agree that the documentation on Rails debugging is *dodgy*.

Add this to environment/test.rb :

# The breakpoint server port that script/breakpointer connects to.
BREAKPOINT_SERVER_PORT = 42531

I wonder why the heck do you need to connect to a remote breakpointer, 
when you can have an IRB session right there in the console? :)

You don''t want to do that. The breakpointer is just a more cumbersome
approach to be dropped right into the IRB session. You only want to
use the breakpointer when interacting with the application through the
browser, or elsewhere, in development mode.
