*** Keywords ***
Initialization Phase
    [Documentation]    Starts mininet and verify if topology is in operational datastore.
    ${mininet_conn_id}=    MininetKeywords.Start Mininet Single Controller
    BuiltIn.Set Suite Variable    ${mininet_conn_id}
    RequestsLibrary.Create Session    session    http://${ODL_SYSTEM_IP}:${RESTCONFPORT}    auth=${AUTH}    headers=${HEADERS_XML}
    BuiltIn.Wait Until Keyword Succeeds    10s    1s    FlowLib.Check Switches In Topology    1

Final Phase
    [Documentation]    Stops mininet.
    BuiltIn.Run Keyword And Ignore Error    RequestsLibrary.Delete Request    session    ${CONFIG_NODES_API}
    MininetKeywords.Stop Mininet And Exit    ${mininet_conn_id}
    RequestsLibrary.Delete All Sessions

Check Master Connection
    [Documentation]    Execute OvsVsctl List Controllers Command and check for master connection.
