Today we are excited to announce additions to the Alexa Skills Kit (ASK) Skill Management API (SMAPI) and the ASK Command-Line Interface (CLI) that provide programmatic access to the full set of skill beta testing functionality available in the ASK developer console. Now you access beta functions from the command line, or build them into your development tools. With skill beta testing, you can get customer feedback on your skill throughout the testing cycle, and make improvements before you release a skill to production.
