Test2::Harness::Runner::DepTracer - Tool for tracing module dependancies as they are loaded.
This tool is used by Test2::Harness to build a graph of dependancies which can then be used to blacklist modified modules (and anything thatuses them) when they change under a preloaded runner.
use Test2::Harness::Runner::DepTracer; my $dt = Test2::Harness::Runner::DepTracer->new(); $dt->start(); require Some::Thing; $dt->stop(); my $dep_map = $dt->dep_map; my $loaded_by = $dep_map->{'Some/Thing.pm'}; print "Some::Thing was directly or indirectly loaded by:\n" . join("\n" => @$loaded_by) . "\n";
These can be specified at construction, and will be populated during use.
A hashref of files/modules to exclude from dep tracking. By default strict and warnings are excluded.
strict
warnings
Every file which is loaded while the tool is started will have an entry in this hash, each value is an array of all files which loaded the key file directly or indirectly.
How many times each file was directly loaded.
Start tracking modules which are loaded.
Stop tracking moduels that are loaded.
