* json resource (et. al.): allow inspec check to succeed when using command When using the `json` resource (or any of the resources that subclass JsonConfig), `inspec check` would fail if the content was supplied with the `command` option. This is because the `command` resource is mocked and an empty string would be returned for `stdout`. That content would be blindly passed to the `parse` method would which raise an exception and cause `inspec check` to fail. This change refactors JsonConfig to be a bit cleaner and use some helper methods. Additionally, we use the new Exceptions to properly raise errors which are naturally caught by Inspec::Profile, etc. Signed-off-by: Adam Leff <adam@leff.co> * Make `resource_base_name` method private Signed-off-by: Adam Leff <adam@leff.co>
