This is an amazing module which speeds up your test suite enormously especially if you are testing a heavy catalyst app with a big DBIC schema.
One test which uses Test::MockTime failed though. Loading Test::MockTime before Test::Aggregate::Nested fixed it and MockTime did what it was supposed to.
The slower a test suite runs, the less likely folk will run it - so Test::Aggregate is a useful addition to my tool set when I've got a traditional set of *.t Perl tests that need to be run more quickly.
When I applied T::A to one $work project I cut 30% off the wall clock time for the core test suite. Useful.
