Usage

To generate test data for eddsa-jcs-2022 tests, testers can specify the issuer name using the environment variable ISSUER_NAME_JCS.

If $ISSUER_NAME_JCS is not specified, bovine will be used.

ISSUER_NAME_JCS="IssuerNameJCS"  npm test

Wrapping Your Implementation

A simplified version of issuer and verifier endpoints from VC API are used by the test suite code to communicate with the underlying cryptosuite. The credentials MUST use the DataIntegrityProof proof type and implement the eddsa-rdfc-2022 and/or eddsa-jcs-2022 cryptosuites.

A community example implementation (written in Node.js/Express) is available at https://github.com/Wind4Greg/Server-for-VCs

The typical server will implement the following endpoints and methods:

POST /credentials/issue
Content-Type: application/ld+json

{
  "@context": [
    "https://www.w3.org/ns/credentials/v2",
    "https://w3id.org/security/data-integrity/v2"
  ],
  "credential": {},
  "options": {}
}

POST /credentials/verify
Content-Type: application/ld+json

{
  "@context": [
    "https://www.w3.org/ns/credentials/v2",
    "https://w3id.org/security/data-integrity/v2"
  ],
  "verifiableCredential": {
    "proof": {}
  }
}

POST /credentials/derive
Content-Type: application/ld+json

{
  "@context": [
    "https://www.w3.org/ns/credentials/v2",
    "https://w3id.org/security/data-integrity/v2"
  ],
  "verifiableCredential": {
    "proof": {}
  }
}

Testing Locally

If you want to test implementations or just endpoints running locally, you can copy localConfig.example.cjs to localConfig.cjs in the root directory of the test suite.

cp localConfig.example.cjs localConfig.cjs

Git is set to ignore localConfig.cjs by default.

This file must be a CommonJS module that exports an array of implementations:

// .localConfig.cjs defining local implementations
// you can specify a BASE_URL before running the tests such as:
// BASE_URL=http://localhost:40443/zDdfsdfs npm test
const baseUrl = process.env.BASE_URL || 'https://localhost:40443/id';
module.exports = {
  settings: {
    enableInteropTests: false, // default
    testAllImplementations: false // default
  },
  implementations: [{
    name: 'My Company',
    implementation: 'My Implementation Name',
    issuers: [{
      id: 'did:myMethod:implementation:issuer:id',
      endpoint: `${baseUrl}/credentials/issue`,
      supports: {
        vc: ['1.1', '2.0']
      },
      tags: ['eddsa-rdfc-2022', 'localhost']
    }],
    verifiers: [{
      id: 'did:myMethod:implementation:verifier:id',
      endpoint: `${baseUrl}/credentials/verify`,
      tags: ['eddsa-rdfc-2022', 'localhost']
    }]
  }];
}

To specifically test only the implementations in localConfig.cjs, change settings.testAllImplementations to false.

Running Specific Tests

This suite uses mocha.js as the test runner. Mocha has multiple options for filtering which tests run.

For example, the snippet below uses grep to filter tests by name and only runs one of the test suites.

mocha --grep '"specificProperty" test name' ./tests/10-specific-test-suite.js

Adding a Public Implementation

To add your implementation to the public list of tested implementations, you will need to add 2 endpoints to your implementation manifest:

A credential issuer endpoint (ex: /credentials/issue) in the issuers property.
A credential verifier endpoint (ex: /credentials/verify) in the verifiers property.

All endpoints will need the tags either eddsa-rdfc-2022 or eddsa-jcs-2022.

A simplified manifest would look like this:

{
  "name": "My Company",
  "implementation": "My implementation",
  "issuers": [{
    "id": "",
    "endpoint": "https://issuer.mycompany.com/credentials/issue",
    "method": "POST",
    "tags": ["eddsa-rdfc-2022"]
  }, {
    "id": "",
    "endpoint": "https://issuer.mycompany.com/credentials/issue",
    "method": "POST",
    "tags": ["eddsa-jcs-2022"]
  }],
  "verifiers": [{
    "id": "",
    "endpoint": "https://verifier.mycompany.com/credentials/verify",
    "method": "POST",
    "tags": ["eddsa-rdfc-2022", "eddsa-jcs-2022"]
  }]
}

The example above represents an unauthenticated endpoint. You may add ZCAP or OAuth2 authentication to your endpoints. You can find an example in the w3c/vc-test-suite-implementations README.

To run the tests, some implementations may require client secrets that can be passed as environment variables to the test script. To see which implementations require client secrets, please check the implementation manifest within the w3c/vc-test-suite-implementations repo.
