The Scala SDK unit tests covered roughly 85% of the codebase, with another ~10+% coming from integration tests that talk directly to Test-Horizon. Whilst the coverage level was very good, relying on integration tests for coverage was problematic, as they can be flaky as a general rule.
Issue https://github.com/Synesso/scala-stellar-sdk/issues/15 & related PR https://github.com/Synesso/scala-stellar-sdk/pull/21 addressed this concern.
There is now 99.82% test coverage, with many of the tests using generative testing techniques (i.e. test data is randomly generated each run with a bias towards finding edge cases).
Side note:
There is about 2 weeks left for the current SBC round. Several items on the Scala SDK issues list are available for people to tackle and submit & I'm happy to work with devs who are curious but unfamiliar with Scala. Talk to me on slack (@Jem), here or directly on the issues list if you're interested.
