v1.1.0: Feature/RSpec integration

Added DnsMock helper which can 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. Added DnsMock::TestFramework::RSpec::Interface, tests
2. Added DnsMock::TestFramework::RSpec::Helper, tests
3. Added RSpec DnsMock config
4. Updated readme, changelog
5. Updated gem version to 1.1.0

v1.0.0: Feature/Configurable record not found behaviour

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 RDNS lookup representatin for IP address in PTR record feature.

1. Updated DnsMock::Server::RecordsDictionaryBuilder
2. Updated gem version to 0.2.1

v0.2.0: Feature/PTR record support

Added 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.

records = {
  '1.1.1.1' => {
    ptr: %w[domain_1.com domain_2.com]
  }
}

DnsMock.start_server(records: records)

dig @localhost -p 5300 -x 1.1.1.1
