Rupert‑Grunt is a development toolchain and library that plugs into a project’s Gruntfile to automate the common tasks needed for building Rupert‑based applications. It provides ready‑made Grunt tasks for running client and server unit tests, generating distributable bundles, and executing end‑to‑end tests with Cucumber and Protractor, making it useful for developers who use the Rupert JavaScript framework and want a streamlined build and test workflow.
