I'm playing with this lib and got an unexpected error 6BCE in my test code. I get an DnssecValidationFailedException for non existing domain "github.xxx".
Here is my test code:
class DnsTest {
enum class AddressStatus {
valid,
notRegistered,
noMxRecord,
unknown
}
@Test
fun evaluating() {
val cases = mapOf(
"github.com" to AddressStatus.valid,
"github.io" to AddressStatus.noMxRecord,
"github.xxx" to AddressStatus.notRegistered,
)
cases.forEach { (domain, expected) ->
val result = checkDomain(domain)
assertEquals("Unexpected result for $domain", expected, result)
}
}
private fun checkDomain(domain: String) : AddressStatus {
return try {
val result = DnssecResolverApi.INSTANCE.resolve<MX>(Question(domain, Record.TYPE.MX))
when {
result.wasSuccessful() && result.answersOrEmptySet.isEmpty() -> AddressStatus.noMxRecord
result.wasSuccessful() && result.answersOrEmptySet.isNotEmpty() -> AddressStatus.valid
result.responseCode == RESPONSE_CODE.NX_DOMAIN -> AddressStatus.notRegistered
else -> AddressStatus.unknown
}
} catch (err: DnssecValidationFailedException) {
println("Error: ${err.message}")
AddressStatus.unknown
} catch (t: IOException) {
AddressStatus.unknown
}
}
}I get the exception: Unexpected result for github.xxx expected:<notRegistered> but was:<unknown>
When I run dig github.xxx +dnssec I get the expected NXDOMAIN status:
; <<>> DiG 9.10.6 <<>> github.xxx +dnssec
;; global options: +cmd
;; Got answer:
