Aries VCX Diaries

Status Live @ [Week 0-1]

[2023-06-13 13:40.30 +0200]

homework: @ Slack

Status:

  • [x] checkout repo
  • [x] run unit tests
  • [ ] run integration tests:
    • [?] run locally instance of Indy blockchain in docker
    • [x] install some runtime dependencies like libzmq, libsodium, libopenssl
    • [?] run instance of our legacy aries mediator service

Updates:

  1. I've summarised my steps for above in a blog post on setting up aries-vcx (build, test)
    steps-to-get-started-developing-with-aries-vcx
  2. Read about and looked into some of the information about Aries. A blog post with summary of last session and some additional content.
    aries-mediator-service-intro-and-motivation

Questions:

  1. I have found some scripts to run indy testnet here.
    https://github.com/hyperledger/indy-node/tree/main/environment/docker/pool
    Is that what needs done? How will that then integrate with the test. (As in how to inform test to use that testnet?)

Immediate Todo:

  1. Run instance of legacy aries mediator service.
    [?? facing some yarn install errors, see status here]
  2. Read through DIDComm, mediator/relay rfc and pickup protocol.

Some Noted Observations:

I did get the unit tests to run, and they do succeed.
However I am also seeing some dynamic errors: Sometimes there's error, sometimes not.

Success

test result: ok. 65 passed; 0 failed; 23 ignored; 0 measured; 0 filtered out; finished in 0.02s

Failure

failures:
    common::proofs::prover::prover_internal::unit_tests::test_find_credential_def_fails
    common::proofs::prover::prover_internal::unit_tests::test_find_schemas_fails

test result: FAILED. 63 passed; 2 failed; 23 ignored; 0 measured; 0 filtered out; finished in 0.01s

Alternate Failures

failures:
    common::proofs::prover::prover_internal::unit_tests::test_find_schemas_fails

test result: FAILED. 64 passed; 1 failed; 23 ignored; 0 measured; 0 filtered out; finished in 0.02s

failures:
    common::proofs::prover::prover_internal::unit_tests::test_find_credential_def_fails

test result: FAILED. 64 passed; 1 failed; 23 ignored; 0 measured; 0 filtered out; finished in 0.02s

Resolution: I have been informed that these tests are no longer required, including for completely different reasons, and can be safely removed.
