Next Level Virtual Machine Maneuver!
summary
Shows how Vagrant and Ruby test tooling get real integration coverage: author builds four mini-test extensions (mini_test_mark, mini_test_parallel, mini_test_speed), uses Vagrant to run OS-specific integration tests (about 50 integration tests that took ~4 hours), and moves slow suites to CI while keeping a fast sanity subset before each commit. Introduces test marking, function-arg style isolation to enable cheap parallel runs, and timed speed tests to track regressions against targets (example: 30 ms API latency).
