Documentation     ODL controller clustering test case using the gherkin syntax.
...
...               This test has a workflow similar to the keyword-driven
...               examples. The difference is that the keywords use higher
...               abstraction level and their arguments are embedded into
...               the keyword names.
...
...               This kind of _gherkin_ syntax has been made popular by
...               [http://cukes.info|Cucumber]. It works well especially when
...               tests act as examples that need to be easily understood also
...               by the business people.

The installed flow remains in the bridge after the controller failure
    Given C1 a controller in cluster of two controllers
    And C2 a controller in cluster of two controllers
    And both controllers get provisioned on all OVS bridges
    And a flow is installed in a bridge
    And C1 see the flow
    And C2 see the flow
    And C1 goes down
    When C1 recovers
    Then C1 see the flow
