# Add Rules Mid-Cycle

This tests for the following behavior when a notification rule is added during a policy.

1. Rules do not retro-actively trigger mid-cycle.
1. New rules take effect, if they occur in the future (mid-cycle).

## Procedure

1. Create 2 rules, 1 immediate, one after 2 minutes.
1. Check the immediate fired.
1. After 2 minutes, check the 2 minute rule fired.
1. Add a rule for 1 minute, and one for 3 minutes.
1. Check that the 1 minute didn't fire.
1. After another minute (3+ total) ensure the 3 minute rule fired.
1. Escalate the alert
1. Ensure the immediate fired.
1. After 1 minute, ensure the 1 minute rule fired.
