...               Query netconf-connector and see if it works. Some testsuites
...               expect netconf-connector to be ready as soon as possible and
...               will fail if it is not. We want to see a failure if this is
...               the cause of the failure.
...
...               If the netconf-connector is not ready upon startup (as seen by
...               the first test case failing), the second case starts to repeat
...               the query for a minute to see whether it is going "to fix itself"
...               within the minute. If yes, then the testcase will pass, which
...               indicates that the "ODL cooldown" of 1 minute is not long enough
...               to allow for netconf-connector to initialize properly.
...
...               If the first test case passed, then the second test case does
...               nothing.

    # TODO: Do not include slash in ${OPERATIONAL_TOPO_API}, having it typed here is more readable.
    # TODO: Alternatively, create variable in Variables which starts with http.
    # Both TODOs would probably need to update every suite relying on current Variables.

Teardown_Everything
    [Documentation]    Destroy all sessions in the requests library.

Check_Netconf_Connector
