I would like to add a step to the PR workflow that runs some sort of integration tests so that we can identify any regressions before merging PRs. It would be nice if the tests where implemented right here in this repository. However, I think the integration tests in https://github.com/WebOfTrust/signify-ts are the most complete ones currently.

I will outline my simple proposal below. Any thoughts or alternative approaches?

Proposal - run signify-ts integration tests

I propose that we add a docker-compose environment similar to the one in signify-ts, it really only needs two small adjustments to run tests from here:

• The keria image would be built on the spot from the source code.
• We can build a "integration test image" also from the source code by cloning the signify-ts repo, I already have an example here: https://github.com/lenkan/signify-integration/blob/main/Dockerfile

Considerations

In case of planned breaking changes, such as changing a endpoint path or adding new required parameters, it would be obvious that the clients need updating ASAP in order to keep the builds healthy.

Another challenge is how to is the potential for false negatives. For example if a bad update to signify-ts causes tests to fail on PRs in keria. Could be solved by pinning the commit of the integration test suite, and only manually upgrade it when needed.
