From af3df2842c22667edf903eb6b5e2e606538c850e Mon Sep 17 00:00:00 2001 From: baude Date: Wed, 10 Jan 2018 14:46:21 -0600 Subject: Test user input to spec Create a mocked CLI instance so we can test that user-input functions to run (create) end up in the spec correctly. It will also help protect against regression include type changes. We can decide if we want to test items one at a time or several at a time.
