# go-mockdns
[](https://godoc.org/github.com/foxcpp/go-mockdns)
Boilerplate for testing of code involving DNS lookups, including ~~unholy~~
hacks to redirect `net.Lookup*` calls.
## Example
Trivial mock resolver, for cases where tested code supports custom resolvers:
r := mockdns.Resolver{
Zones: map[string]mockdns.Zone{
"example.org.": {
A: []string{"1.2.3.4"},
},
},
}
addrs, err := r.LookupHost(context.Background(), "example.org")
fmt.Println(addrs, err)
// Output:
// [1.2.3.4]
~~Unholy~~ hack for cases where it doesn't:
srv, _ := mockdns.NewServer(map[string]mockdns.Zone{
"example.org.": {
A: []string{"1.2.3.4"},
},
}, false)
defer srv.Close()
srv.PatchNet(net.DefaultResolver)
defer mockdns.UnpatchNet(net.DefaultResolver)
addrs, err := net.LookupHost("example.org")
fmt.Println(addrs, err)
// Output:
// [1.2.3.4]
Note, if you need to replace net.Dial calls and tested code supports custom
net.Dial, patch the resolver object inside it instead of net.DefaultResolver.
If tested code supports Dialer-like objects - use Resolver itself, it
implements Dial and DialContext methods.
