 ## Automated Testing

 To run the tests locally run

 ```bash
 $ make test
 ```
 
 This will first clear out any leases in the local database. We run `perfdhcp` to emulate a number of clients and multiple [DORA](https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol#Operation) cycles. We then check how many leases have been created to ensure the server is operating as expected. The `dhcp_test.sh` will exit with a non zero exit code if all of the leases have not been created.
 
 ## Container Health Checks
-To ensure that an invalid task does not get into the production ecs cluster, a boostrap script has been writen. This uses ```perfdhcp``` to ensure that an IP can be leased. If this fails, a notification will be sent to the critical notifcation topic and forwarded to developers. This check is not done locally.
