MockResolver is a struct used to simulate resolver behavior for testing purposes.

func (*MockResolver) LookupAddr

func (m *MockResolver) LookupAddr(ip string) ([]string, error)

LookupAddr simulates reverse DNS lookup for testing.

func (*MockResolver) LookupCNAME

func (m *MockResolver) LookupCNAME(host string) (string, error)

LookupCNAME simulates DNS lookup for CNAME records for testing.

func (*MockResolver) LookupIP

func (m *MockResolver) LookupIP(host string) ([]net.IP, error)

LookupIP simulates DNS lookup for A or AAAA records for testing.

func (*MockResolver) LookupMX

func (m *MockResolver) LookupMX(host string) ([]*net.MX, error)

LookupMX simulates DNS lookup for MX records for testing.

func (*MockResolver) LookupNS

func (m *MockResolver) LookupNS(host string) ([]*net.NS, error)

LookupNS simulates DNS lookup for NS records for testing.

func (*MockResolver) LookupTXT

func (m *MockResolver) LookupTXT(host string) ([]string, error)
