perldb

[Doug MacEachern <do...@covalent.net>]

to help with debugging tests, you can run under the perldebugger
% t/TEST -v -d perl t/modules/cgi.t 

...
  DB<1> lwpd 1

will turn on debug mode so Apache::TestRequest prints the request method
and url, along with the response headers from the server.  'lwp 2' does
the same, but includes response body.  any non \d argument triggers a call
to LWP::Debug::import, "lwp '+'" for example, see 'perldoc LWP::Debug' for
more info on those options.

i find it handy to set a breakpoint at 'ok', so the debugger stops each
time a test happens:
  DB<2> b ok
  DB<3> c
then you'll see:
1..35

type 'c' at the prompt to continue on to the next test.

'perldoc perldebug' for more info on using the perl debugger.

that doesn't seem to work

% t/TEST -start
% t/TEST -v -d perl t/apache/read.t 
setting ulimit to allow core files
ulimit -c unlimited
 exec t/TEST -v -d perl t/apache/read.t

Editor support available.

Enter h or `h h' for help, or `man perldebug' for more help.

Apache::TestPerlDB added perldb commands:
   bok - Set breakpoint at test n
   lwpd - Set the LWP debug level for Apache::TestRequest
Debugged program terminated.  Use q to quit or R to restart,
  use O inhibit_exit to avoid stopping after program termination,
  h q, h R or h O to get additional info.
