I have a dns server running on the host in a virtual machine with the IP 192.168.99.169
If I run the dns queries I get these responses
dig:
dig @192.168.99.169 hello-john.test
result:

Everything works correctly for the dns server. If I update the dns servers on the mac so that the only dns server is 192.168.99.169 then things also work the same way but I don't have to specify the dns server. For example:
Update the dns servers
networksetup -setdnsservers Wi-Fi 192.168.99.169
dig:
dig hello-john.test

Completely overriding the dns servers does not work for me since need to have multiple ip addresses that are searched.
I reset the dns servers to a normal dns server.
networksetup -setdnsservers Wi-Fi 8.8.8.8
I create a file /etc/resolver/test
with the contents:
domain test
nameserver 192.168.99.169
search_order 1
timeout 5
I can test that the resolver was loaded correctly with scutil:
scutil --dns
result:
DNS configuration
resolver #1
nameserver[0] : 8.8.8.8
flags : Request A records
reach : 0x00000002 (Reachable)

However when I run dig or nslookup it is not using the resolver. I am guessing this has something to do with the order that the resolver configs are used.
dig:
dig hello-john.test
result:

If I turn off my Wi-Fi I just see that resolver #1 from scutil --dns
just shows as
DNS configuration
resolver #1
flags :
reach : 0x00000000 (Not Reachable)
I believe I am missing some configuration in /etc/resolver/test
but I cannot find a way to make sure it gets used.
Thanks for your help!
Even though nslookup and dig do not return a correct response it seems that I can still ping the host
ping:
ping hello-john.test
result:
PING hello-john.test (192.168.99.169): 56 data bytes
64 bytes from 192.168.99.169: icmp_seq=0 ttl=64 time=0.259 ms
64 bytes from 192.168.99.169: icmp_seq=1 ttl=64 time=0.390 ms
This works good enough for my purposes
