tl;dr/Executive Summary ----------------------- Harvest the internal improvements from Test::Builder2 for Test::Builder creating a backwards compatible Test::Builder 1.5 which accomplishes the lion's share of the grant deliverables. Have a feature complete alpha release before the end of November.
Background ---------- The TPF Grant for Test::Builder2 is due to be shut down at the end of November along with all the other "old style" grants which do not have reporting requirements. They've been far more than patient. I have a final crack at submitting a last report before the end of November to determine some level of success. Details ------- After thinking about it some, at this point the most speculative and least developed part of Test::Builder2 is, ironically, Test::Builder2. That is, the backwards incompatible class which replaces Test::Builder as the interface for test authors. All the rest: the formatter, results, events, etc... are solid improvements which can be used by Test::Builder. This will still introduce alternative formatters and event hooks (except "assert failed"). This gives us things like a safer Test::NoWarnings. It also remains possible to write additional builders which work in coordination. The critical thing Test::Builder2 brought in was stacked asserts. Those eliminate the need to play around with $Level and also provide a reliable "assert fail" event. So we don't get that with Test::Builder 1.5... but we weren't getting that usefully until test modules switched over to TB2 anyway. The Test::Builder2 branch already has an operational Test::Builder which is using the new TB2 pieces. Test::Builder 1.5 would focus on finishing the conversion of a backwards compatible, improved Test::Builder, rather than designing Test::Builder2. The primary hurdles remain the same: supporting threads and subtests in the new formatter/event model. It's not hard, it's just work I have to do. I've set up a milestone with the outstanding 1.5 issues. https://github.com/schwern/test-more/issues/milestones -- I have a date with some giant cartoon robots and booze.
