  rrset "xxx.info.winebarrel.jp.", "A" do
    dns_name "elb-dns-name.elb.amazonaws.com"
  end

  rrset "zzz.info.winebarrel.jp", "A" do
    set_identifier "Primary"
    failover "PRIMARY"
    health_check "http://192.0.43.10:80/path", :host => "example.com"
    ttl 456
    resource_records(
      "127.0.0.1",
      "127.0.0.2"
    )
  end

  rrset "zzz.info.winebarrel.jp", "A" do
    set_identifier "Secondary"
    failover "SECONDARY"
    health_check "tcp://192.0.43.10:3306"
    ttl 456
    resource_records(
      "127.0.0.3",
      "127.0.0.4"
    )
  end
end

Test

Routefile compares the results of a query to the DNS and DSL in the test mode.

shell> roadwork -t
..F..
info.winebarrel.jp. A:
  expected=127.0.0.1(300),127.0.0.3(300)
  actual=127.0.0.1(300),127.0.0.2(300)
5 examples, 1 failure

(Please note test of A(Alias) is not possible to perfection...)
