Description
What for is that MR?
Consul-service robot tests we have alert by name "ConsulIsDownAlarm" to make this alert activated we need the test case "Consul Is Down Alert" as it was failing we modified it and wrote tin below mentioned 2 ways.

Implementation details
Consul-service robot tests we have alert by name "ConsulIsDownAlarm" to make this alert activated we were deleting all the pods but it was not activating the alert. To make that alert active we need have used 2 approches 'changing memory to very low values' and 'changing the readiness probe unhealty'. In this tests we first capture the existing details and change to make pods unhealty and once alert is activated revert it back to orginal values.
Finally we were asked to use memory approach, keeping that removing the other changes.

Test cases
"Consul Is Down Alert" we had now re-wrote it into 2 ways "Consul Is Down Alert Using Memory Changes" and "Consul Is Down Alert Using Readiness Probe"
