Team's Response

The module website tasking in week 7 only required us to "Give use cases (textual form) for a few representative user stories that need multiple steps to complete." https://nus-cs2103-ay2122s2.github.io/website/schedule/week7/project.html#5-update-the-dg-user-stories-glossary-nfrs-use-cases

The use cases mentioned in the issue have already been mentioned in our user stories.

Items for the Tester to Verify

:question: Issue response

Team chose [response.Rejected]

• [x] I disagree

Reason for disagreement: This states that DG bugs include missing use cases with multiple extensions.

Adding user can result in the following extensions:

• duplicate email/nric/phone number
• Invalid username (special characters)
• Invalid format of command

Searching user can result in the following extensions:

• No result with arguments
• invalid format of command

Searching user can result in the following "sub use case":

• Search with sort
• Search with find

Since these 2 features will be used most of the time and encountering the listed extensions are fairly likely, they should be included in the use case.

Also, these use cases are not found in your DG as you stated. You only have the following use case

• delete applicant
• mark applicant job as pending
• edit date
