DESCRIPTION

This debugger plugin extends the debugger's b command - used to set breakpoints - with the ability to stop at a specific test number. Andy Armstrong had the idea and wrote the original code, see http://use.perl.org/~AndyArmstrong/journal/35792.

METHODS

initialize

Sets up the command handler that checks whether the command is of the form b #12 or b #12, 34, .... If so, it sets breakpoints to break as soon as the given test has finished. If test-based breakpoints have been found, the standard DB::cmd_b() function that handles the b command is short-circuited.

If it handles the command, it enables the watchfunction().

This plugin overwrites Test::Builder::lock() to be able to detect that a test is about to be finished - see the source code of Test::Builder for details. Yes, this is nasty. It also means that this plugin will break Test::Builder when using threads.

watchfunction

Checks the current test number from Test::Builder and instructs the debugger to stop if an appropriate test number has been reached.
