Definition of Done

• Integrate slack with the HRIS.
• Users must receive notifications twice, one before their shift, and the other one on or after their shift start time.
• In the same message there should be and action button that allows user to log in.
• Once the login button is clicked, the time in functionality in the HRIS will be triggered automatically, and the user will be reverted with feedback of success or fail.

Notes

• Once set for actual deployment, we'll have to coordinate with the admin of Sun*'s slack for additional setup.
• Checkers for notification sending are set every twenty minutes, while being equipped with caching to ensure efficient performance.
• Slack's rate limiting tiers have been taken into considered into crafting the api integrations.

Pre-condition

• Create a new user with an email of "[email protected]". This is a must.
• Slack app must be configured.
• Once for staging deployment, the nestjs and redis servers must be up

Expected Output

• All items marked as complete in the definition of done section must be working.

Screenshots/Recordings

Notes

• The screen recording is a bit long since i was waiting for the notification sending to be triggered (time based)
• The starting time elapsed at the end seems to be a local environment issue since it does not occur in staging. I would like to it get tested in staging as well.
