Testing the Multiverse
summary
A concrete workflow emerges: a small gem straw is built around Bales to collect a productivity metric, tests run against multiple gemfiles via the BUNDLE_GEMFILE trick and a rake Multiverse task, bundler install is optimized with a fast local check and fallback to full install, version quirks are handled with runtime feature checks and gated tests, failures aggregate exit codes, parallel runs use threads to avoid fork problems on JRuby, and a bundler with clean debug path lets single runs be inspected.
