As a system administrator
I need the ability to update a counter to a new value
So that user reported errors in counting can be adjusted

Details and Assumptions

-Use the action POST /counters/{name}/setValue/{value}

Given the counter is set to 4
When I call setValue to 7 on the service
And I request the current counter
Then I should see 7 returned from the service
