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