10# Accept Friend Request

[ttomkk]

User story

As a student I want to be able accept friend request from another student, so that another student can have access to my specific, otherwise private, information and I can have access to their specific, otherwise private, information (to synchronize our study process).

(Student can see timetable, planned exams ... of his friends because they can synchronize their exams and see when the friend has free time or a lecture.)

Use case

Starting situation (Initial assumption)

• Student B received a friend request from student A. Student B was notified by email about new friend request.

  Normal

  1. Student B clicks on Personal information module.
  2. System loads menu with options for student B.
  3. Student B clicks on "my Friends" sub-module.
  4. System loads "my Friends" sub-module and options for student B.
  5. Student B clicks on "Friends Requests".
  6. System shows friends requests that were send to student B with options "Accept" and "Decline"
  7. Student B finds friend request from student A and clicks on "Accept".
  8. System updates list of friend requests of student B (deletes friend request from student A), updates list of friend requests of student A (deletes friend request to student B), updates list of friends of student B (adds new friend - student A), updates list of friends of student A (adds new friend - student B).
