Ability to specify custom priority of MX record if it needed

Now is possible to define null or backup MX records. Please note, if you haven't specified a priority of MX record, it will be assigned automatically. MX records builder is assigning priority with step 10 from first item of defined MX records array.

records = {
  'example.com' => {
    mx: %w[.:0 mx1.domain.com:10 mx2.domain.com:10 mx3.domain.com] # .:0 - null MX record
  }
}

DnsMock.start_server(records: records)

dig @localhost -p 5300 MX example.com

; <<>> DiG 9.10.6 <<>> @localhost -p 5300 MX example.com

;; ANSWER SECTION:
example.com. 1 IN MX 0 .
example.com. 1 IN MX 10 mx1.domain.com.
example.com. 1 IN MX 10 mx2.domain.com.
example.com. 1 IN MX 40 mx3.domain.com.

RSpec native support. DnsMock helper help you to simplify integration with RSpec

# spec/support/config/dns_mock.rb
require 'dns_mock/test_framework/rspec'

RSpec.configure do |config|
  config.include DnsMock::TestFramework::RSpec::Helper
end

# your awesome first_a_record_spec.rb
RSpec.describe FirstARecord do
  subject(:service) do
    described_class.call(
      hostname,
      dns_gateway_host: 'localhost',
      dns_gateway_port: dns_mock_server.port
    )
  end

  let(:hostname) { 'example.com' }
  let(:first_a_record) { '1.2.3.4' }
  let(:records) { { hostname => { a: [first_a_record] } } }

  before { dns_mock_server.assign_mocks(records) }

  it { is_expected.to eq(first_a_record) }
end

[1.0.0] - 2021-01-29

Added

Configurable strategy for record not found case

By default it won't raise an exception when DNS record not found in mocked records dictionary:

DnsMock.start_server(port: 5300)

dig @localhost -p 5300 A example.com

; <<>> DiG 9.10.6 <<>> @localhost -p 5300 A example.com

DnsMock.start_server(exception_if_not_found: true)

Fixed

[0.2.0] - 2021-01-26

Added

PTR record support. Ability to mock PTR records

Please note, you can define host address without RDNS lookup prefix (.in-addr.arpa). DnsMock will do it for you.

  '1.2.3.4' => {
    ptr: %w[domain_1.com domain_2.com]
  }
}

DnsMock.start_server(records: records)

dig @localhost -p 5300 -x 1.2.3.4
