Background

Implementations added to this package are tested against various test suites in order to demonstrate interoperability.

Security

Please do not commit any sensitive materials such as oauth2 client secret or client secrets used for signing zcaps or HTTP Signature Headers.

Install

• Node.js 18+ is required.

NPM

To install via NPM:

npm install w3c-ccg/vc-test-suite-implementations

Development

To install locally (for development):

git clone https://github.com/w3c-ccg/vc-test-suite-implementations.git
cd vc-test-suite-implementations
npm install

Usage

Adding a new implementation

Please add implementations to the ./implementations directory. Implementation configuration files are expressed in JSON and use roughly the following form:

{
  "name": "My Company",
  "implementation": "My Implementation Name",
  "oauth2": {
     "clientId": "bar",
     "clientSecret": "CLIENT_SECRET_MY_COMPANY",
     "tokenAudience": "https://product.example.com",
     "tokenEndpoint": "https://product.example.com/oauth/token"
  },
  "issuers": [{
    "id": "urn:uuid:my:implementation:issuer:id",
    "endpoint": "https://product.example.com/issuers/foo/credentials/issue",
    "zcap": {
      "capability": "{\"@context\":[\"https://w3id.org/zcap/v1\",\"https://w3id.org/security/suites/ed25519-2020/v1\"],\"id\":\"urn:uuid:4d44084c-334e-46dc-ac23-5e26f75262b6\",\"controller\":\"did:key:zFoo\",\"parentCapability\":\"urn:zcap:root:https%3A%2F%2Fmy.implementation.net%2Fissuers%2Fz19wCeJafpsTzvA6hZksz7TYF\",\"invocationTarget\":\"https://my.implementation.net/issuers/z19wCeJafpsTzvA6hZksz7TYF/credentials/issue\",\"expires\":\"2022-05-29T17:26:30Z\",\"proof\":{\"type\":\"Ed25519Signature2020\",\"created\":\"2022-02-28T17:26:30Z\",\"verificationMethod\":\"did:key:z6Mkk2x1J4jCmaHDyYRRW1NB7CzeKYbjo3boGfRiefPzZjLQ#z6Mkk2x1J4jCmaHDyYRRW1NB7CzeKYbjo3boGfRiefPzZjLQ\",\"proofPurpose\":\"capabilityDelegation\",\"capabilityChain\":[\"urn:zcap:root:https%3A%2F%2Fmy.implementation.net%2Fissuers%2Fz19wCeJafpsTzvA6hZksz7TYF\"],\"proofValue\":\"zBar\"}}",
      "keySeed": "KEY_SEED_DB"
    },
    "tags": ["vc-api"]
  }],
  "verifiers": [{

    "endpoint": "https://product.example.com/verifiers/z19uokPn3b1Z4XDbQSHo7VhFR/credentials/verify",

      "keySeed": "KEY_SEED_DB"
    },
    "tags": ["vc-api"]
  }]
}

Please note: implementations may have security using oauth2 or zcaps, but not both. Implementations may also contain no security (do not add a OAUTH2 or ZCAP section in that case).

Testing locally

If you need to test implementations for endpoints running locally, create a config file in the root dir of the test suite:

.localImplementationsConfig.cjs

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

// file .localImplementationsConfig.cjs
module.exports = [{
  "name": "My Company",
  "implementation": "My Implementation Name",
  "issuers": [{
    "id": "urn:uuid:my:implementation:issuer:id",
    "endpoint": "https://localhost:40443/issuers/foo/credentials/issue",
    "tags": ["vc-api", "localhost"]
  }],
  "verifiers": [{
    "id": "https://localhost:40443/verifiers/z19uokPn3b1Z4XDbQSHo7VhFR",
    "endpoint": "https://localhost:40443/verifiers/z19uokPn3b1Z4XDbQSHo7VhFR/credentials/verify",
    "tags": ["vc-api", "localhost"]
  }]
}];

To run the tests only against the localhost implementation, update the test suite to filter implementations using the specified tag in your config file.

For instance, if your .localImplementationsConfig.cjs looks like above in the vc-api-issuer-test-suite, you can adjust the tag to filter the implementation by localhost rather than vc-api and then run the tests.

Opting into a Test Suite

Please Note:

1. Tags serve as identifiers to determine which test suites to run on your issuers and verifiers. The first issuer/verifier found with a specific tag from your list will be run against the test suite, while subsequent issuers and verifiers bearing the same tag won't. This applies to most of the test suites associated with this implementations repository listed below.

For instance, if you have added the tag vc-api to all your issuers and verifiers to run them with vc api issuer and verifier test suites, only the first match will be used in the test suites. In the sample configuration below, only the issuer and verifier with the IDs https://product.example.com/issuers/z1AEwLo7tZ3TrsPgRcgLJqQvR and https://product.example.com/verifiers/z1AEwLo7tZ3TrsPgRcgLJqQvR will be selected. Therefore, please avoid adding duplicate tags.

Example

// Only the first match https://product.example.com/issuers/z1AEwLo7tZ3TrsPgRcgLJqQvR
// and https://product.example.com/verifiers/z1AEwLo7tZ3TrsPgRcgLJqQvR will be
// run against the VC API issuer and verifier test suites.
{
  "issuers": [{
    "id": "https://product.example.com/issuers/z1AEwLo7tZ3TrsPgRcgLJqQvR",
    "endpoint": "https://product.example.com/issuers/z1AEwLo7tZ3TrsPgRcgLJqQvR/credentials/issue",
    "tags": ["vc-api"]
  }, {
    "id": "https://product.example.com/issuers/z4Rq7N1lT6zVwFgXk8JYdCcKpU",
    "endpoint": "https://product.example.com/issuers/z4Rq7N1lT6zVwFgXk8JYdCcKpU/credentials/issue",
    "tags": ["vc-api"]
  }],
  "verifiers": [{
    "id": "https://product.example.com/verifiers/z1AEwLo7tZ3TrsPgRcgLJqQvR",
    "endpoint": "https://product.example.com/verifiers/z1AEwLo7tZ3TrsPgRcgLJqQvR/credentials/verify",
    "tags": ["vc-api"]
  }, {
    "id": "https://product.example.com/verifiers/z4Rq7N1lT6zVwFgXk8JYdCcKpU",
    "endpoint": "https://product.example.com/verifiers/z4Rq7N1lT6zVwFgXk8JYdCcKpU/credentials/verify",
    "tags": ["vc-api"]
  }]
}

2. If you want your issuer or verifier to run against multiple test suites, you can assign multiple tags to them, eliminating the need for redundant entries. For instance, if an issuer with the ID https://product.example.com/issuers/z1AEwLo7tZ3TrsPgRcgLJqQvR can be run with both the Status List 2021 and VC API test suites, a single entry with multiple tags can be used. This consolidated entry, containing tags for both VC API and Status List 2021 test suites, ensures that the issuer and the verifier will be run against both test suites. Here is an example of how to structure the entry:

For Example:

{
  "issuers": [{
    "id": "https://product.example.com/issuers/z4Rq7N1lT6zVwFgXk8JYdCcKpU",
    "endpoint": "https://product.example.com/issuers/z4Rq7N1lT6zVwFgXk8JYdCcKpU/credentials/issue",
    "tags": ["vc-api", "StatusList2021", "Suspension"]
  }],
  "verifiers": [{
    "id": "https://product.example.com/verifiers/z4Rq7N1lT6zVwFgXk8JYdCcKpU",
    "endpoint": "https://product.example.com/verifiers/z4Rq7N1lT6zVwFgXk8JYdCcKpU/credentials/verify",
    "tags": ["vc-api"]
  }]
}

VC API Issuer and Verifier Test Suites

• vc-api - This tag will run the vc-api-issuer tests on your issuer and the vc-api-verifier tests on your verifier.

NOTE: Currently the vc api verifier test suite uses Ed25519Signature2020 as the default signature for the mock VCs that are sent to the verifiers since it is most widely implemented. So, the verifier you add for vc-api must support verification of VCs with Ed25519Signature2020 signature to pass verification tests.

As of 2023, Ed25519Signature2018 is no longer supported, so please update your existing implementations to use Ed25519Signature2020 if you were previously using Ed25519Signature2018.

Status List 2021 Test Suite

• StatusList2021 and Revocation/Suspension- Combining the StatusList2021 tag with Revocation or Suspension tags will run the Status List 2021 tests on your issuer and/or verifier.
  • Adding the Revocation tag alongside StatusList2021 runs tests for issuers or verifiers issuing/verifying VCs with the revocation status purpose.
  • Adding the Suspension tag alongside StatusList2021 runs tests for issuers or verifiers issuing/verifying VCs with the suspension status purpose.
  • Note: To update the status of VCs and publish the updated status, additional endpoints setStatusLists - /credentials/status and publishStatusLists
  • /credentials/publish may also need to be specified.

DID Key Test Suite

• did-key - This tag will run the DID Key Test Suite on your DID resolver endpoint.
