Sending notifications

[basvas-jkj]

As a teacher, I need to be able to send enrolled students notifications of subject description changes through communication channel because it might impact students decisions.

Use case

Starting situation

There are students who attend a subject, that subject has a description written by a teacher. The students also have a communication channel.

Normal

1) Teacher edits the description of a subject he administers. 2) Teacher is prompted if he wants to send a notification to the attendees. 3) If he chooses "yes", all students attending the lecture are send a message through the communication channel. 4) The edited description is saved into the database

What can go wrong

• Message doesnt go through because of some short term internet issue
• Teacher closes the site without choosing whether to notify students of the change

System state on completion

• Students inbox has one more message
• The subject description is changed.
