*** Test Cases ***
Add Service Functions To First Node
    [Documentation]    Add service functions from JSON file
    Create Session    session    http://${ODL_SYSTEM_IP}:${RESTCONFPORT}    auth=${AUTH}    headers=${HEADERS}
    ${jsonbody}    Read JSON From File    ${SFC_FUNCTIONS_FILE}
    Add Elements To URI From File    ${SFC_API}    ${SFC_FUNCTIONS_FILE}    ${HEADERS_YANG_JSON}
    ${resp}    RequestsLibrary.Get Request    session    ${SFC_API}
    Should Be Equal As Strings    ${resp.status_code}    200
    ${result}    To JSON    ${resp.content}
    Lists Should be Equal    ${result}    ${jsonbody}

Read Service Functions From Second Node
    Create Session    session    http://${ODL_SYSTEM_2_IP}:${RESTCONFPORT}    auth=${AUTH}    headers=${HEADERS}
    ${jsonbody}    Read JSON From File    ${SFC_FUNCTIONS_FILE}
    ${resp}    RequestsLibrary.Get Request    session    ${SFC_API}
    Should Be Equal As Strings    ${resp.status_code}    200
    ${result}    To JSON    ${resp.content}
    Lists Should be Equal    ${result}    ${jsonbody}

Read Service Functions From Third Node
    Create Session    session    http://${ODL_SYSTEM_3_IP}:${RESTCONFPORT}    auth=${AUTH}    headers=${HEADERS}
    ${jsonbody}    Read JSON From File    ${SFC_FUNCTIONS_FILE}
    ${resp}    RequestsLibrary.Get Request    session    ${SFC_API}
    Should Be Equal As Strings    ${resp.status_code}    200
    ${result}    To JSON    ${resp.content}
    Lists Should be Equal    ${result}    ${jsonbody}

*** Keywords ***
Read JSON From File
    [Arguments]    ${filepath}
    ${body}    OperatingSystem.Get File    ${filepath}
    ${jsonbody}    To Json    ${body}
    [Return]    ${jsonbody}

Init Variables
    [Documentation]    Initialize ODL version specific variables
    log    ${ODL_VERSION}
    Run Keyword If    '${ODL_VERSION}' == 'stable-lithium'    Init Variables Lithium
    ...    ELSE    Init Variables Master

Init Variables Master
    [Documentation]    Sets variables specific to latest(master) version
    Set Suite Variable    ${SFC_API}    /restconf/config/service-function:service-functions
    Set Suite Variable    ${SFC_FUNCTIONS_FILE} ${CURDIR}/../../../variables/sfc/master/service-functions.json

Init Variables Lithium
    [Documentation]    Sets variables specific to Lithium version
    Set Suite Variable    ${SFC_API}    /restconf/config/service-function:service-functions
    Set Suite Variable    ${SFC_FUNCTIONS_FILE} ${CURDIR}/../../../variables/sfc/lithium/service-functions.json
