Requirements and acceptance tests – an example

Requirement id: REQ1 Title: Group chat management – adding users to a group Text: A user can add new users to the group. The addition of a new user must be first approved by the admin. The admin can modify personal data and the status of a user. Test id: AT1 Title: Test for REQ1 (Group chat management – adding users to a group) Prerequisites: Internet connection is needed. Steps: Expected results:

1. Log-in as user

Login is successful

2. Open the page

The page is opened and the list with users’ groups

f groups is visible
3. Click on the button The group members are listed

"Manage group” next and there is a button “Add users” to the Group 1. in the upper, right corner. … …

State of the art

Keep software documentation aligned using Information Retrieval and Natural Language Processing methods for identifying impacted documents.

SLIDE 18

State of the art

Gaps in the current methods:

Less applied between requirements and acceptance

tests

Only identify which documents are impacted by a

change, but not suggest how to manage the change

7

SLIDE 19

The goals of our approach (GuideGen)

1. Support test engineers in making decisions on

how to modify impacted acceptance tests,

2. Ensure on-time and smooth communication of

changes between requirements and test engineers.

When requirements evolve:

An example of requirement changes and generated suggestions

A user can add new users to the group. The addition of a new user must be first approved by the admin. The admin and the user can modify personal data and the status of that a

user. Only user can modify

its status. The admin must be logged-in in order to modify personal data of a user.
