Feature: IXFR out
    Tests for IXFR-out, specific for BIND 10 behaviour.
    These are (part of) the tests as described on
    http://bind10.isc.org/wiki/IxfrSystemTests

    # A lot of these tests test specific UDP behaviour.
    #
    # Where possible, we use the TCP equivalent. Some of the behaviour
    # tested is UDP-specific though. In either case, a comment above
    # the test shows how and why it differs from the test specification,
    # or why it is commented out for now.
    # When we do implement UDP IXFR, we should probably keep the TCP
    # tests, and add them to the test specification, so we still have a
    # 1-to-1 mapping between these tests and the specification document.
    #
    # These tests use a zone with just a few records, the first serial
    # is 2, and it is incremented in steps of 2, up to serial 22.
    # Each updates either deletes or adds the www.example.com A record.
    # Version 2 has the record, then the update to version 4 deletes it,
    # the update to 6 adds it again, and so on, until version 22 (where
    # the last update has added it again)
    #
    # Some of the tests (scenario 1 tests 3 and 4, and scenario 2 tests 1 and
    # 2 may still not work if we replicate BIND 9's behaviour; it always
    # responds to UDP IXFR requests with just the SOA, and it does not do
    # AXFR-style IXFR if the number of changes exceeds the size of the zone)
    #
    # So in effect, there is only one test that is currently active (scenario
    # 1 test 7)


    Scenario: Test Set 1
        Given I have bind10 running with configuration ixfr-out/testset1-config.db

        And wait for bind10 stderr message BIND10_STARTED_CC
        And wait for bind10 stderr message CMDCTL_STARTED
        And wait for bind10 stderr message AUTH_SERVER_STARTED
        And wait for bind10 stderr message XFROUT_STARTED
        And wait for bind10 stderr message XFRIN_STARTED
        And wait for bind10 stderr message ZONEMGR_STARTED

        The SOA serial for example.com should be 22
