You have confused "domain" with "zone".

You have a zone named 'cloudns.tk.'. A zone is also a domain. Within that domain, you have the following subdomains (that you have mentioned):

test.cloudns.tk.
s1.test.cloudns.tk.
*.cloudns.tk.

All of these domain names are the apexes of domains. None of those domains are broken out (delegated) as zones (with SOA records).

What everyone so far has been trying to tell you is, even though you have no records named 'test.cloudns.tk.', its existence as a domain name is implied by the existence the child, 's1.test.cloudns.tk.'. Therefore, the wildcard will not match queries for those two domain names. Nor will it match any other domain names within those two domains -- you would need A records for the following names to cover all of the names other than s1.test:

test.cloudns.tk.
*.test.cloudns.tk.
*.s1.test.cloudns.tk.
