about: improving the cli unit tests

Is your feature request related to a problem? Please describe

The current CLI unit tests are not correctly named for what they are testing in some cases. Also the tests that call through the cli are calling to functions in different classes. This causes the unit tests to rely on outside tools (trivy and grype as examples).

Describe the solution you'd like

The cli unit to more accurately reflect what they are actually doing in the names and not call through to other functions when calling the cli.
