Resolve

A Node JS testing application to test DNS records against pre-defined expected results. It can be useful to automate testing when changing NS or other DNS Records.

Resolve uses native Node JS APIs and has no dependencies.

Installing

Make sure you have Node JS installed before you proceed. Once installed, set your working directory to where you have cloned the repository.

Then run:

npm install

Configuration

There are sample test cases in tests.sample.json. Rename this file to tests.json and configure to your needs.

Test cases will need to be configured as an Array of Objects. The format for an individual object is:

  {
    "type": "[RECORD TYPE]",
    "host": "[HOSTNAME]",
    "expected_value": [
      "[MULTIPLE]",
      "[STRING]",
      "[VALUES]",
      "[ALLOWED]"
    ],
    "hard_fail": true | false
  },

For example, to check Google's NS Records:

  {
    "type": "NS",
    "host": "google.com",
    "expected_value": [
      "ns1.google.com",
      "ns2.google.com",
      "ns3.google.com",
      "ns4.google.com"
    ],
    "hard_fail": true
  },

The hard_fail value determines if a warning (false) or an error (true) is thrown for the test case. We can be used to easily distinguish essential and non-essential records in the output.

Resolve supports the following types of DNS records:

• A
• AAAA
• CNAME
• CAA
• MX
• NAPTR
• NS
• PTR
• SOA
• SVR
• TXT

Running the Application

After you have completed setup use npm run start to run the tests.
