Feature: patroni api
We should check that patroni correctly responds to valid and not-valid API requests.
Scenario: check API requests on a stand-alone server
Given I start postgres0
And postgres0 is a leader after 10 seconds
When I issue a GET request to http://127.0.0.1:8008/
Then I receive a response code 200
And I receive a response state running
And I receive a response role master
When I issue a GET request to http://127.0.0.1:8008/replica
Then I receive a response code 503
When I issue an empty POST request to http://127.0.0.1:8008/reinitialize
Then I receive a response code 503
And I receive a response text "I am the leader, can not reinitialize"
When I issue a POST request to http://127.0.0.1:8008/failover with leader=postgres0
Then I receive a response code 503
And I receive a response text "failover is not possible: cluster does not have members except leader"
When I issue an empty POST request to http://127.0.0.1:8008/failover
Then I receive a response code 503
And I receive a response text "No values given for required parameters leader and member"
Scenario: check API requests for the primary-replica pair
Given I start postgres1
And replication works after 10 seconds
When I issue a GET request to http://127.0.0.1:8009/replica
Then I receive a response code 200
And I receive a response state running
And I receive a response role replica
When I issue an empty POST request to http://127.0.0.1:8009/reinitialize
Then I receive a response code 200
Given replication works after 10 seconds
When I issue an empty POST request to http://127.0.0.1:8008/restart
Then I receive a response code 200
And postgres0 is a leader after 5 seconds
Scenario: check promotion via the API
Given I issue a POST request to http://127.0.0.1:8008/failover with leader=postgres0,candidate=postgres1
Then I receive a response code 200
And postgres1 is a leader after 10 seconds
