Machinepack Test Runner

test-machinepack provides a raw command-line test runner specifically designed for `node-machine` 'machinepacks'. Its current stable version is 3.0.1, though the last known development activity dates back to 2017, suggesting it is in maintenance mode rather than active development. While it includes a basic, generic test driver, the documentation explicitly recommends against using it for production testing, instead pointing to more robust, community-maintained drivers like `test-machinepack-mocha`. The primary function of this package is to expose a consistent interface for running tests defined in JSON or JSON5 format within a machinepack's `tests` directory, thereby enabling custom test drivers to integrate seamlessly with the `node-machine` ecosystem.
