Invalid command for delete contact not shown

[cx0810]

When user inputs an invalid command with valid commands in delete, no error message is displayed to indicate to users that certain fields are invalid. For instance, there are no contact with the name Jay, however there is no error message shown.

Team's Response

This was the intended behaviour we wanted as the end result is that there are no contacts with the name "Jay", contacts with the tag "friend" and contacts in the module "CS2103". This also does not affect any of the functionality of the application.

Team chose [response.Rejected]

• [x] I disagree

Reason for disagreement: The program shouldn't allow for invalid inputs to be entered together with valid inputs to give a valid result since it is a false positive. While it does not affect any functionality of the application, users are not allowed to delete an invalid input by itself, so they shoudn't be given the ability to attempt to delete an invalid input when put together with a valid input.
