I think you could probably write another small app if you really need to do testing right at the CLI that know what inputs and outputs to look for. A miniature "postman" for your app. I would submit that you should first make sure everything before the CLI is tested correctly. If you have internal tests for all logic/processing/CRUD in your application there is really very little to test at the CLI. What functionality or behavior are you wanting to test there that can't be tested internally?
