@austb thanks for the PR. Do you know a bit about the int vs core+ext test suites? I tried to understand the original matrix that Perforce used, but it's all a bit confusing. Should we add pg18 to int as well?

Do you know a bit about the int vs core+ext test suites? I tried to understand the original matrix that Perforce used, but it's all a bit confusing.

core tests reference the basic lein tests of OpenVoxDB, so just testing the Clojure code.

ext reference these tests which actually build a JAR and test the behavior of that JAR. Typically, you'd find these types of tests written as Beaker acceptance tests, but for various reasons (mostly someone didn't want to be on the VPN...) it was done in these tests instead.

integration tests are just that. Testing the integration of the DB, Server, and Agent. They clone the repos of those other two projects and run a "full system" using these integration/ tests. There it makes sense to vary the Ruby version because the agent is run via bundle exec.

Should we add pg18 to int as well?

Yeah probably good to add it there too. Will do.

The test matrix looks reasonable to me now.

I had one question about the integration test set, but probably best to handle that separately so I opened #84

Looks reasonable to me. Nothing crazy stands out and any other concerns I may have had were already answered in existing threads
