Task 2: Push Notifications

Let's define three objects:

1. user
2. message
3. notify (boolean)

with user: user.status user.state user.push_tokens

with message: message.state message.content

with idle: 15 minutes

There are three possible conditions:

1. message.state = 'pending' if user.state == 'online' and user.status != 'idle'

Test: if user.state = active and user.status != idle assert message.state == 'pending' assert pre-message.content is equal to the post-message.content pushed. assert notify == false

2. message.state = 'pushed' if user.state == 'online' or user.status == 'idle'

Test: if user.state == 'online' or user.status == 'idle' assert message.state == 'pushed' assert notify == true assert pre-message.content is equal to post-message.content pushed. assert notify count == user.push_tokens count

3. message.state = 'pushed' if user.state == 'offline' or user.status == 'idle'

Test: if user.state == 'offline' or user.status == 'idle' assert message.state == 'pushed' assert notify == true assert pre-message.content is equal to post-message.content pushed. assert notify count == user.push_tokens count

Flow:

1. Send message
2. Save the message.content into a pre-message variable
3. api GET users/:id to get the user object
4. Run the assertions written above based on the user's state and status.
